BACKGROUNDThe present disclosure relates generally to building security systems for assets (e.g., buildings, building sites, building spaces, people, cars, equipment, etc.). The present disclosure relates more particularly to security platforms for handling alarms for the building, risk analytics, and risk mitigation.
Many security platforms provide threat information to operators and analysts monitoring all the activities and data generated from building sensors, security cameras, access control systems, etc. The data may be, or may be indicative of alarms, i.e., events occurring in the building that indicate an intrusion, a fire, or any other dangerous event. Furthermore, the data may be external, e.g., data from data sources reporting potential threats e.g., violent crimes, weather and natural disaster reports, traffic incidents, robbery, protests, etc. However, due to the volume of data for the activities and the dynamic nature of the activities, a large amount of resources are required by the security platform to process the data. Since there may be many alarms, not only does the security platform require a large amount of resources, a high number of security operators and/or analysts are required to review and/or monitor the various different alarms or systems of the building.

Understanding the relationship between an asset and the set of threats is a complex task that require an infrastructure that can gather all the relevant data from different sources, analyze the data in multiple processing steps and generate rich yet easy to understand information to security operators and site monitors so that these personal can take appropriate actions. The analytics systems and methods as described herein can generate risk information for use in prioritization of alarms, presenting users with contextual threat and/or asset information, reducing the response time to threats by raising the situational awareness, and automating response actions. In case of mobile assets, another block to the analytics system can be included to identify the location of the mobile asset since the location of the mobile asset will be dynamically changing while the the rest of the pipeline of the analytics system may remain the same.
The analytics system as described herein can be configured to uses various components to provide scalability and reliable security solutions. The analytics system can be configured to ingest threat data from multiple disparate data sources. The threat data can be information indicating a particular threat incident, i.e., an event that may put the building or other asset at risk (e.g., a chance of personal injury, theft, asset damage, etc.). Based on the ingested threat data, the analytics system can identify which of a collection of stored assets are affected by the threat, e.g., by performing geofencing with geofences of the assets and reported locations of the threat data. Based on the indication of assets affecting threats, the analytics system can perform risk analytics via an analytics pipeline to perform operations such as risk calculation for the threat and asset, risk decay, and various other analytical operations.
Furthermore, based on the analyzed threat and asset data, the analytics system can present information to a user, e.g., a security officer, via user interface systems. The user interface system can facilitate alarm handling by providing contextual information together with risk scores for particular threats. Using the risk asset score for an alarm event, security personnel can filter and/or sort alarm events to show or highlight the highest risk alarms.

The network 104 can communicatively couple the devices and systems of system 100. In some embodiments, network 104 is at least one of and/or a combination of a Wi-Fi network, a wired Ethernet network, a ZigBee network, a Bluetooth network, and/or any other wireless network. Network 104 may be a local area network or a wide area network (e.g., the Internet, a building WAN, etc.) and may use a variety of communications protocols (e.g., BACnet, IP, LON, etc.). Network 104 may include routers, modems, servers, cell towers, satellites, and/or network switches. Network 104 may be a combination of wired and wireless networks.
Via the network 104, the risk analytics system 106 can be configured to ingest (receive, process, and/or standardize) data from data sources 102. The data sources 102 can be located locally within a building or outside a building and can report threats for multiple buildings, cities, states, countries, and/or continents. The data sources 102 can be local building systems, e.g., access control systems, camera security systems, occupancy sensing systems, and/or any other system located within a building. Furthermore, the data sources 102 can be government agency systems that report threats, e.g., a police report server providing the risk analytics system 106 with police reports.
The data sources can be analytics companies e.g., Dataminr, NC4, Lenel on Guard, and/or any other analytics system configured to collect and/or report threats. Dataminr is a service that monitors social media data and generates alarms on different topics. Dataminr can be configured to send alarms generated from twitter data to the risk analytics system 106. NC4 can be configured to generate incidents and/or advisory alerts and provide the incidents and/or alerts to the risk analytics system 106. NC4 can include local resources on different parts of the globe to collect data for generating the incidents and/or advisory alerts. Lenel is a system that manages the entrance, badge monitoring and etc. in a building.
The risk analytics system 106 can be configured to support any type of data source and is not limited to the data sources enumerated above. Any live feed of potential threats according to the vulnerabilities of the asset under protection can be used as a data source for the risk analytics system 106.
The threat data reported by the data sources 102 can include time information, location information, summary text, an indication of a threat category, and a severity indication.
Threat Data={Time Information, Location Information, Summary Text, Category, Severity}
In some embodiments, the data sources 102 are configured to provide time information, e.g., date and time information for reported threats to the risk analytics system 106. In some embodiments, the current time stamp can be attached to the incoming threats. However, this timing information may be different for different data sources, for example, some data sources may indicate that a current time of the data provided by the data source is the time of that threat occurring. In this regard, for data from data sources that indicate that the time of a threat is the time that the threat data is received, the risk analytics system 106 can add the time of threat occurrence as the time that the threat was received.
The data source can provide the location information on the incident. The location information could be the latitude and longitude of the incident. Both point and area information can be included. For example, some incidents like weather related threats affect a large area and they are not a specific point on the map but rather a particular geographic area. However, some other incidents like traffic incidents, bombing, or urban fires may be associated with a specific point on a map. The threat data can further include summary text or otherwise a text explanation of the incident should also be included in the threat reported.
Furthermore, the threat data can include an indication of a category of the incident. For example, each of the data sources 102 can define a category for the threat data, e.g., crime, fire, hurricane, tornado, etc. Each of the data sources 102 may have a unique category scheme. For example, one data source could define a shooting as a “Crime” category while another data source would define the same event as a “Violent Activity” category. If no category is reported by a data source, the risk analytics system 106 can be configured to determine a category from the text summary of the threat using Natural Language Processing (NLP).
The threat data can include severity information. Threats might be different in terms of severity. In order to understand the potential risk for that specific threat, the severity information can be included in the threat data. Different scales can be used for different data sources (e.g., 1-10, 1-5, A-F, etc.). The risk analytics system 106 can be configured to convert the severity levels to a standard format as part of ingesting data from the data sources 102.
The data sources 102 can provide real-time updates on potential and/or actual threats. Depending on the application, the data sources 102 may differ significantly in the formatting and/or reporting scheme of the data source. There should be some analysis done on the asset vulnerability before deciding on what data sources are suitable to report the potential threats. For example if the main vulnerability of the asset is towards natural disasters and extreme weather conditions then a proper channel that provides real-time updates on the weather conditions and forecast would be an appropriate data source for the risk analytics system 106.
Another example is social media information. If a reputation of a company is part of the asset the risk analytics system 106 is to protect or the way consumers share their feedback and thoughts on social media are a good indication of possible threats to hurt the company reputation. Then a data source that reports updates on social media topics and trends can be valuable for the risk analytics system 106. This can be extended to sensors and camera feeds that monitor a building or campus and generate alarms (threats) that need to be ingested and analyzed to deduce the best action possible. The data sources 102 can either be first party and/or third party, i.e., platforms and/or from equipment owned by an entity and/or generated by data sources subscribed to by an entity.
The risk analytics system 106 can be a computing system configured to perform threat ingesting, threat analysis, and user interfaces management. The risk analytics system 106 can be a server, multiple servers, a controller, a desktop computer, and/or any other computing system. In some embodiments, the risk analytics system 106 can be a cloud computing system e.g., Amazon Web Services (AWS) and/or MICROSOFT AZURE. The risk analytics system 106 can be an off-premises system located in the cloud or an on-premises system located within a building of the entity and/or on a campus.
Although the risk analytics system 106 can be implemented on a single system and/or distributed across multiple systems, the components of the risk analytics system 106 (the data ingestion service 116, the geofence service 118, the RAP 120, and the risk applications 126) are shown to include processor(s) 112 and memories 114. In some embodiments, the risk analytics system 106 is distributed, in whole or in part, across multiple different processing circuits. The components of the risk analytics system 106 can be implement on one, or across multiple of the memories 114 and/or the processors 112 such that, for example, each of the data ingestion service 116, the geofence service 118, the RAP 120, and/or the risk applications 126 could each be implemented on their own respective memories 114 and/or processors 112 or alternatively multiple of the components could be implemented on particular memories and/or processors (e.g., two of or more of the components could be stored on the same memory device and executed on the same processor).
The processor(s) 112 can be a general purpose or specific purpose processor, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a group of processing components, or other suitable processing components. The processor(s) 112 may be configured to execute computer code and/or instructions stored in the memories 114 or received from other computer readable media (e.g., CDROM, network storage, a remote server, etc.).
The memories 114 can include one or more devices (e.g., memory units, memory devices, storage devices, etc.) for storing data and/or computer code for completing and/or facilitating the various processes described in the present disclosure. The memories 114 can include random access memory (RAM), read-only memory (ROM), hard drive storage, temporary storage, non-volatile memory, flash memory, optical memory, or any other suitable memory for storing software objects and/or computer instructions. The memories 114 can include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described in the present disclosure. The memories 114 can be communicably connected to the processor(s) 112 and can include computer code for executing (e.g., by the processor(s) 112) one or more processes described herein. The memories 114 can include multiple components (e.g., software modules, computer code, etc.) that can be performed by the processor(s) 112 (e.g., executed by the processor(s) 112). The risk analytics system 106 is shown to include a data ingestion service 116. The data ingestion service 116 can be configured to receive, collect, and/or pull threat data from the data sources 102 via the network 104.
The data ingestion service 116 can be configured to bring all relevant information on potential threats and/or actual threats into the risk analytics system 106 (e.g., based on insights gained from historical threat data analysis or data received from data sources 102). The data ingestion service 116 can perform various transformations and/or enrichments to the incoming threats and forward the transformed and/or enriched threats to the next stages of the pipeline of the risk analytics system 106, e.g., geofence service 118, RAP 120, and/or risk applications 126. The data ingestion service 116 can be configured receive threats in a variety of different formats and standardize the threats into a standard threat schema.
The risk analytics system 106 is shown to include the geofence service 118. The geofence service 118 can be configured to receive the standard threats from the data ingestion service 116 and determine which of multiple assets are affected by the threats. For example, assets, e.g., buildings, cities, people, building equipment, etc. can each be associated with a particular geofence. If a location of the standard threat violates the geofence, i.e., is within the geofence, the geofence service 118 can generate a specific threat object for that asset. In this regard, a single threat can be duplicated multiple times based on the number of assets that the threat affects. The geofence service 118 can communicate with threat service 122. Threat service 122 can be configured to buffer the threats received from data ingestion service 116 in queue or database, e.g., the threat database 124.
The standard threats can be provided by the geofence service 118 to the RAP 120. The RAP 120 can be configured to determine various risk scores for different assets and threats based on the standard threats. For example, for an asset, the RAP 120 can be configured to determine a dynamic risk score which is based on one or multiple threats affecting the asset. Furthermore, the RAP 120 can be configured to determine a baseline risk score for the asset which indicates what a normal dynamic risk score for the asset would be. In some embodiments, the baseline risk score is determined for particular threat categories. For example, the baseline risk score for a building may be different for snow than for active shooters.
Risk analytics system 106 is shown to include the risk applications 126. The risk applications 126 can be configured to present risk information to a user. For example, the risk applications 126 can be configured to generate various risk interfaces and present the interfaces to a user via the user devices 108 via network 104. The risk applications 126 can be configured to receive the risk scores and/or other contextual information for assets and/or threats and populate the user interfaces based on the information from the RAP 120. The user interfaces as described with reference to
The risk applications 126 are shown to include a monitoring client 128 and a risk dashboard 130. The risk dashboard 130 can provide a user with a high level view of risk across multiple geographic locations, e.g., a geographic risk dashboard. An example of a risk dashboard that the risk dashboard 130 can be configured to generate and mange is shown in
The user devices 108 can include user interfaces configured to present a user with the interfaces generated by the risk applications 126 and provide input to the risk applications 126 via the user interfaces. User devices 108 can include smartphones, tablets, desktop computers, laptops, and/or any other computing device that includes a user interface, whether visual (screen), input (mouse, keyboard, touchscreen, microphone based voice command) or audio (speaker).

Each of the threats 206-210 is in different schema and the scale of metric (e.g., severity and threat category schema) of the threats 206-210 may be different. For example, the severity levels of the threats 206-210 can be on a 1-5 scale or on a 1-3 scale. Furthermore, the threats 206-210 can have different naming for the fields in their data schema even though they represent the same piece of information like different names for the same threat categories.
The ingestion operators 212 can be configured to perform processing operations on the threats 206-210 to generate standard threats and put the standard threats in scalable queue 222 before forwarding the threats 224-228 to other services (e.g., the geofence service 118). The ingestion operators 212 are shown to include a standardize operator 214, an expiry time predictor 216, an NLP engine 218, and a cross-correlator 220. The standardize operator 214 can be configured to convert the schema (e.g., severity scales, data storage formats, etc.) of the threats 206 to a standard schema and generate corresponding standard threats 224-228 (e.g., defined data objects with particular attributes).
Expiry time predictor 216 can be configured to generate, via various timing models, how long the threats 206-210 will last, i.e., when the threats 206-210 will expire. The expiry time may be added to the standard threats 224-228 as a data element. NLP engine 218 can be configured to categorize the threats 206-210. Since the category included in each of threats 206-210 may be for a different schema, the NLP engine 218 can perform natural language processing on a category and/or summary text of the threats 206-210 to assign the threats to a particular category. The assigned categories can be included in the threats 224-228. The cross-correlator 220 can be configured to group the threats 224-228. Since multiple sources 200-204 are generating the threats 206-210, it is possible that two sources are reporting the same incident. In this regard, the cross-correlator 220 can be configured to perform cross-correlation to group threats 224-228 that describe the same incident so as not to generate duplicate threats.
Where available, a threat expiration time can be extracted by the expiry time predictor 216 from a threat. If the expiration time cannot be extracted from the threat, the expiry time predictor 216 can be configured to use analytics performed on the historical threat data to determine the threat expiration time. For example, a traffic incident may be expected to take a particular amount of time to be responded and handled by the local authorities given the severity, type and location of the threat calculated periodically from similar historical incidents can be used to determine the threat expiration time. If the threat expiration time cannot be identified from the threat parameter database, a static or default threat expiration time can be used. The threat expiration time for the threat and/or asset can be stored in the active threats database 328.

In step 252, the data collector 230 can pull data from the data sources 102. Data collector 230 can implement multiple processes in parallel to pull data from the multiple data sources. In this regard, step 252 is shown to include steps 254, 256, and 258, each of the steps 254, 256, and 258 can include pulling data from a particular data source, e.g., a first data source, a second data source, and a third data source, the data sources 200-204.
In step 260, the standardize operator 214 can convert threats pulled from multiple data sources to standardized threats. More specifically, the standardize operator 214 can convert a first threat to the standard threat 224, a second threat to the standard threat 226, and a third threat to the standard threat 228. Each of the standard threats converted can be received from different data sources and/or the same data source.
Different formats and data schemas might be used by the different data sources and thus each threat may have a different schema. In step 260, the standardize operator 214 can perform multiple operations to convert all the incoming threats to a standard threat objects, the standard threats 224-228. The standardize operator 214 can perform one or multiple (e.g., a series) of static mappings. For example, the standardize operator 214 can adjusting the scales for severity levels of the threats using the same naming for the data fields that present in all the ingested threats like the summary, location info and category. The step 260 is shown to include multiple sub-steps, convert first threat 262, convert second threat 264, and convert third threat 266. The steps 262-266 indicate the steps that the standardize operator 214 can perform (e.g., either in parallel or in sequence) to convert the threats received in the steps 254-258 into the standard threats 224-228.
Part of the conversion of the step 260 into the standard threats 224-228 may include identifying a category for each of the incoming threats, the category being added and/or filled in the standard threats 224-228. The categories can be identified via the NLP engine 218. In this regard, the standardize operator 214 can perform a call to the NLP engine 218 to cause the NLP engine 218 to identify a category for each of the threats received in the step 252. In response to receiving the call to the step 268 (and/or the original threats themselves), the NLP engine 218 can identify a category for each of the incoming threats.
In step 270, expiry time predictor 216 can predict an expiry time for each of the standard threats 224-228. The expiry time may indicate how long it will take a particular threat to expire, e.g., how long it takes for the effects of an incident to be resolved and/or be eliminated. The step 270 can be made up of multiple processes (performed in parallel or performed in series), i.e., the steps 274, 276, and 278, each step including predicting an expiry time for each of the standard threats 224-228. The expiry time predictor 216 may call an expiry time model 280 (step 272) to determine the expiry time for each of the standard threats 224-228. The expiry time model 280 can generate an expiry time for each of the standard threats 224-228 based on the information of the standard threats 224-228 (e.g., the category of the threat, a description of the threat, a severity of the threat, etc.). The expiry time model 280 can be a component of the expiry time predictor 216 or otherwise a component of the data ingestion service 116.
The data ingestion service 116 can add the standard threats 224, 226, and 228 into the scalable queue 222. The scalable queue 222 could have different implementations like Apache Kafka or Azure Eventhubs in various embodiments. The queue 222 is designed in a way that it can ingest large volume of incoming messages and is able to scale horizontally. In step 282, the cross-correlator 220 can group related threats together so that threats that describe the same event are de-duplicated. The result of the cross-correlation by cross-correlator 220 can be grouped threats 284 which can include groups of multiple threats reported by different data sources each relating to the same event. The grouped threats 284 can be added back into the scalable queue 222 and/or forwarded on to the geofence service 118. The scalable queue 222 can be implemented via Apache Kafka and/or Azure Event-hubs and can buffer the incoming traffic until the running processes e.g., the steps 260, 270, 282) finish processing them.

The result of the enrichment by the asset information enricher 302 is the enriched threat 308. The enriched threat 308 can include an indication of a threat, an indication of an asset affected by the threat, and contextual information of the asset and/or threat. The RAP 120 includes risk engine 310 and risk score enricher 312. Risk engine 310 can be configured to generate a risk score (or scores) for the enriched threat 308. Risk engine 310 can be configured to generate a dynamic risk score for the enriched threat 308. The risk score enricher 312 can cause the dynamic risk can be included in the enriched threat 316 generated based on the enriched threat 308.
Bach process manager 318 can implement particular processes that are configured to generate dynamic risk 332 and baseline risk 334 for presentation in a user interface of risk applications 126. Batch process manager 318 is shown to include risk decay manager 320, threat expiration manager 322, and base risk updater 324. Each of the components of batch process manager 318 can be implemented as a batch process and executed by the batch process manager 318. Risk decay manager 320 can be configured to determine and/or decay a dynamic risk score of the enriched threat 316 based on a particular decay model (e.g., a linear decay model, an exponential decay model, a polynomial decay model, etc.). In this regard, the risk decay manager 320 can cause a value of the dynamic risk score to lower over time.
The batch process manager 318 is shown to communicate with databases, risk decay database 326, active threats database 328, and base risk database 330. The risk decay database 326 can store risk decay models and/or associations between particular threats and/or assets and particular decay models. The risk decay manager 320 can call the risk decay database 326 to retrieve particular decay models and/or decay parameters based on an asset and/or threat. The active threats database 328 can store an indication of an expiration time for the threat expiration manager 322. In some embodiments, the active threats database 328 stores models for determining a threat expiration time for a threat and/or asset. The base risk database 330 can store an indication of a base risk value for each of multiple different threat categories for particular assets that the base risk updater 324 can be configured to determine.
The threat expiration manager 322 can be configured to expire, e.g., delete, a threat based on an expiration time. The expiration time can be included within the enriched threat 316 and can be generated by the expiry time predictor 216 as described with reference to
The risk decay manager 320 can be a mechanism for dynamically changing a risk score of an asset over time to more accurately represent the actual significance of an alarm event associated with an asset. The risk decay manager 320 can be configured to apply a decay model that reduces risk score over time. The parameters of the models can be learned by the risk decay manager 320 from historical data making the model adaptive towards ever-changing nature of threats. The decaying asset risk score can be used by the risk applications 116 to sort and filter threats occurring in relation to that asset. The order of the threats displayed (e.g., in a list) can change based on the risk decay performed by the risk decay manager 320.
The risk decay manager 320 can determine a decay model based the type of threat. The risk decay manager 320 can be implemented in the RAP 120 and/or in the risk applications 126. Decay models define how the risk changes over time and can be tuned for specific applications. Examples of decay models can be exponential decay models, polynomial decay models, and linear decay models. Examples are shown in
Using the polynomial decay model facilitates a dynamic decay that can be adapted for particular situations. For example, the polynomial could incorporate a factor to account for the time of day that could change the decay curve for night time events. The polynomial model also captures the natural progress of the risk in most scenarios by a slow decay at the beginning of the curve then a fast decay when approaching the estimated threat expiration time for that threat. This behavior is observed in many threats that reflect how the situation is handled after first responders are at the scene. The slope of the curve is configurable for each type of threats to best match the natural dynamic of that threat in specific. The decay models can be automatically selected for different assets, asset types, and threat categories.
Using the decayed risk score and/or other risk scores for other assets, the risk applications 126 can sort and/or filter the threats for display on a user interface. In this regard, one threat may immediately rise to the top of a threat list but over time fall down the threat list due to the decay determined by the risk decay manager 320. An interface could include selectable monitoring zones and threat events. Each threat event may have a type, a date, a time, an identifier (ID) number, an alarm location, and a risk score. The risk score of the event is the risk score associated with the asset under threat. The threats can be sorted by multiple properties including risk scores.
The decay process performed by the risk decay manager 320 can continue until the risk score returns to the baseline asset risk score or the estimated duration is reached. Additionally, the risk of a specific threat can be eliminated if such a notification is received from the original event source. For example, a weather update notifying that the tornado has stopped. The risk score can also be updated by accessing data feeds from external sources. For example, the tornado severity classification is upgraded by another weather service (or multiple sources). The risk score will change and evolve to reflect the actual risk of the event. The result of a risk decay is a more realistic and reflective of how risk scores should evolve.

The type of threats might be very different from one asset to another. The master list 502 can act as a union of all the threats that might impact any of the assets of the building and/or the site. With reference to
Many data sources provide the category and sub-category information about the reported threats. In some cases there might be a static mapping between those threats and the master threat list 502. However, a direct static mapping might not exist for all the categories. In
It can be seen that there is a static mapping for some categories and sub-categories but for example for criminal activity there is no direct mapping to any of the sub-categories on the master list. To be able to accurately identify the sub-category of the crime discussed in the threat summary, the NLP engine 218 can be configured to process the textual summary of the threat to find the closest sub-category on the master list that will be a good representation of the topic for that threat.

The process 600 can be the operation performed by the standardize operator 214 and/or a message (an HTTP request) sent from the standardize operator 214 to the NLP engine 218 to get the threat category for the new incoming threats. The standardize operator 214 can talk to a high-performance web server, the web server 602, that can be configured to work as a reverse proxy relaying all the incoming requests to the underlying WSGI server 604.
It is the reverse proxy implemented via the web server 602 that exposes the NLP engine 218 to the outside world (e.g., the standardize operator 214). This provides solid security and scalability built-into the NLP engine 218. The web server 602 can be different in different embodiments but can be Nginx web servers and/or Apache web servers. The WSGI server 604 can be a scalable server that can process requests in parallel. There are many different options for WSGI servers. For example, the WSGI server 604 can be a Gunicorn server. The WSGI server 604 can be configured to communicate with the underlying WSGI application 606 in order to do the calculations and return the results of the classification. The classification model 608 can be a Machine Learning model that is used by the WSGI application 606 to do the categorization of the threats.

In step 702, the threats service 122 can store historical threats coming into the system 106 in the threat database 124. All the threats can be ingested and stored for analytics by the threats service 122. The ingested historical threat data stored in the threat database 124 can be utilized to develop a language model.
In step 704, the NLP engine 218 can perform pre-processing on the stored threats. Pre-processing can include the initial steps in the NLP pipeline. The text summary of the threats coming in might include a lot of noise, links, and characters that do not have any significant meaning for the purpose of risk modeling. In this step, the NLP engine 218 can remove the links, text words or phrases which are too short or too long, and/or the stop words along with the special characters (e.g., “&,” “!,” etc.)
In step 706, after filtering out some of the threats in the pre-processing step 704, the NLP engine 218 can label a small portion of the threats with the corresponding standard categories that the system supports, e.g., the categories as shown in the master list 502 of
The requirements can further include having good coverage on all the categories on the list of the threats that are picked from the historical threat store should be distributed among all the categories. For example, there may need to be example labelled threats in every category. A minimum 20 examples in each category may be required to cover all the categories in the model. Furthermore, considering the preceding requirement, the distribution of the threats that are picked up for labeling should not disturb the natural frequency of threats in categories drastically. This means that the ingested data by nature has more threats on crime category than weather incidents for example. The sampling strategy can respect this bias and have more samples in crime category picked for labeling.
In step 708, after the labeling is performed in the step 706, n-grams can be extracted from the raw text of the labeled threats by the NLP engine 218. Going beyond bigrams may have has little to no value added for the increased complexity of the model. In this regard, the n-grams may be limited to unigrams and bigrams. Examples of unigrams and bigrams may be specific highly occurring words for word groups. For example, bigrams (2-grams) could be “Police Shooting,” “Gas Fire,” and “Armed Robbery” while examples of unigrams (1-grams) can be “Police,” “Fire,” and “Robbery.”
In step 710, the NLP engine 218 can vectorize the extracted n-grams (e.g., the unigrams and bigrams). The extracted n-grams can be vectorized in a high-dimensional vector space. Vectorizing the n-grams enables the NLP engine 218 to work with numbers instead of words. The NLP engine 218 can be configured to utilize bag of words and/or count-vectorizer to vectorize the n-grams. Vectorizing may indicate the frequency at which particular words occur, in the example of bag-of words vectorization, a bag-of-words data structure could be,
BoW={“Fire”:40, “Shooting”:20, “Rain”:3, “Heavy Rain”:2};
which indicates that the unigrams “Fire,” “Shooting,” and “Rain” occurred 40, 20, and 3 times respectively and the bigram “Heavy Rain” occurred twice.
In some embodiments the class imbalance in the data might be too big to ignore. In response to detecting a class imbalance, the NLP engine 218 can perform, in step 712, over-sampling of the minority classes and/or under-sampling of majority classes. The NLP engine 218 can perform resampling (over-sampling and/or under-sampling) based on the Imbalanced-learn Python library.
In some cases, the number of features for the classifier is very large. Not all the features have the same level of importance in training a model. The features that are not strongly relevant to the classification can be removed by the NLP engine 218 with minimal impact on the accuracy of the classification model 608. For this reason, in step 714, the NLP engine 218 can select the most importance features for classification. The NLP engine 218 can be configured to perform a statistical relevance tests like χ2 (Chi-Squared) test can be used as a measure of importance of a feature. Scikit-learn library for Python can be implemented by the NLP engine 218 to perform the selection. In some embodiments, the NLP engine 218 can select a predefined number (e.g., the top 10 percent) of the most importance features. Selected features can be particular n-grams that are important.
In step 716, the NLP engine 218 can split the data set of the selected features of the step 714 into a test data set 720 and a training data set 718. The ratio between test and training data might be different in different applications. In some embodiments, the training data set 718 is larger than the testing data set 720. In some embodiments, the training data set includes 80% of the data set while the testing data set includes 20% of the data set.
The NLP engine 218 can train the classification model 608 using the training data set 718 in step 722. The classification model 608 can be one or multiple different classifiers. The classification model 608 can be a Naive Bayes and/or Random Forrest model. Naive Bayes may be not as accurate as Random Forest but it has the speed advantage compared to Random Forest. Depending on the size of the data and number of features, Naive Bayes can be much faster to train compared to Random Forest. However, if pure accuracy is the ultimate goal Random Forest may be the best choice.
In step 724, the testing data set 720 can be used by the NLP engine 218 to test the trained classification model 608 and make sure the classification model 608 provides satisfactory performance. Precision and Recall per class needs to be calculated to evaluate the model. If the trained classification model 608 is successfully tested (e.g., has an accuracy above a predefined accuracy level), the NLP engine 218 establishes the classification model 608 by deploying the classification model 608 on the WSGI application 606 within in the NLP engine 218 (step 726). If the classification model 608 is not good enough (has an accuracy below the predefined accuracy level), the training process needs to repeat with more data, different features and different model parameters until the satisfactory results are achieved (e.g., repeat the process 700 again any number of times).

The labeling tool can be a component connected to the threats service 122 and can be configured to load the threats stored in the threat database 124, apply the pre-processing to filter out the noisy threats and then provides the threats one by one to the user via the interface 800 to generate labels for each threat based on user input indicating the labels. In interface 800, a potential threat that has been reported from social media (e.g., TWITTER, FACEBOOK, etc.) has been loaded and the possible labels for that tweet are suggested as options to be picked for the user in element 802. The user selects all the labels of the element 802 that apply to that threat and then accepts the labels by pressing the checkmark button 808. This causes the selected labels to be moved from element 802 to a list in element 804. In case the threat loaded is not suitable for labeling (e.g., it does not have clear relevance to the threat categories) the user can skip that threat and go to the next threat by pressing the “x” button 806. The buttons 806 and 808 can be included in the interface 800 to satisfy the requirement that only threats that clearly fall into a category are labeled otherwise they are skipped.
The interface 800 is shown to include demo mode element 810 which can include text “Demo Mode” and “End Demo Mode.” The demo mode enables new users to get familiar with the labeling tool without generating inaccurate labels on the system. This feature helps the users to quickly interact with the tool and feel confident about what they will be doing with the tool before the actual labeling begins.

In step 1002, the threat service 122 stores received and ingested threats in the threat database 124, e.g., historical threats. The step 1002 may be the same as and/or similar to the step 702 as described with reference to
The stored threats, in step 1006, can be vectorized by the NLP engine 218. For example, the stored threats can be fed by the NLP engine 218 into the Word2Vec. The step 1006 can be the same and/or similar to the step 710 as described with reference to
The word vectors that result from perform the step 1006 can be used to obtain sentence embeddings by the NLP engine 218 in step 1010. There are multiple ways (e.g., calculating averages) to determine a sentence embedding. In some embodiments, the sentence embedding is determined according to the process described in Y. L. T. M. Sanjeev Arora, “A SIMPLE BUT TOUGH-TO-BEAT BASELINE FOR SENTENCE Embeddings,” in International Conference on Learning Representations (ICLR), Toulon, France, 2017.
In step 1011, a user can select one or multiple categories for a threat using the labeling tool. Based on the sentence embeddings of the step 1010 and the selected categories of the step 1018, the NLP engine 218 can, in step 1012 perform a similarity analysis (e.g., a cosine similarity analysis) to determine and assign (in step 1014) a score for each of the categories for each of the threats. For example, each threat can include a score for each of the categories.
In step 1018, the labeling tool can use the similarity score to filter which labels are recommended to a user for confirming which labels are appropriate for particular threats (e.g., suggest categories with a score above a predefined amount and/or select a predefined number of the highest scored categories). After the initial labels are put on some data that labeled data (the step 1011) that is used to calculate the similarity of those labels to the new coming threats. The most relevant labels are shown to the user and the rest of the categories are dropped from the list. This helps the user to be able to quickly identify the potential labels without getting inundated with all the possible labels. In step 1020, the NLP engine 218 can select the category and/or categories for a particular threat based on the scores (e.g., select the highest score). Using the similarity score to select the label for a threat can be used as an alternative and/or together with the classification model 608.

Many data sources send out updates about the threats as they develop. After the incident has been closed, the data sources set the status of that threat to closed. This information is sometimes sent out as updates (push model) and some other times, an explicit call is required to get the status updates is needed. Depending on the data source API the implementation of the process that pulls data can be different. However, in the threat database 124 of the system 106 the records of the times when an incident was first reported and the time that it was closed or updated. Using that historical data on the incidents that are monitored, the expiry time predictor 216 can build a machine learning model that can be used for predicting the expiry time of the incidents the moment they come into the pipeline. This predicted expiry time can be used by the risk decay manager 320 and can enable users to have forecasting capability on the incidents that come in by knowing approximately how long it will take to be closed or dealt with.
In step 1102, threats are stored as historical data in the threat database 124 by the threat service 122. In step 1104, the expiry time predictor 216 can prepare the stored threats. Cleaning the stored threats can include removing the data that has missing fields, removing the data that has zero or negative expiry time. The expiry time is calculated by subtracting the time the threat was reported and the time that the threat was closed/updated. In practical applications there are always cases in which the data provided includes some inaccuracies and mistakes. The expiry time predictor 216 can verify that those are removed before using that data for training.
Other than the data that include fields that are inaccurate, there are some extreme cases that are considered outliers and those usually do not represent the trends and insights about the data. So by removing those outliers in the step 1106 by the expiry time predictor 216 it can be ensured that high quality data is used in training. A simple example for this type of data can be a false incident report. If there was a bomb threat reported by mistake but after few seconds it was removed or closed by the analyst who posted it to avoid the confusion. Those types of threats will appear with a very short expiry time which is very unusual to the other valid incidents. Thus those threats are removed by the expiry time predictor 216 is removed from further processing. The techniques used can be Modified Z-Score and Inter Quartile Range (IQR).
Regarding expiry time, the output can range from very small positive values (minutes) to very large values e.g., days. This can correspond to a variety of factors for example the type of the threat. Minor traffic incidents might take only a few minutes to be cleared but a major wild fire might take days to be dealt with. In order to build a model that predicts the exact time of the expiration, there may need to be a limit on the possible classes that a threat can belong to. By defining a set of labels based on the percentile of the expiry time the expiry time predictor 216 can label the data in step 1108. This can create many (e.g., hundreds) different type of classes that each threat can belong to. In some applications there might be less and in some there might be more classes defined. For example, a 10 class labeling distribution (e.g., a histogram analysis of expiry time) is shown in
After applying the labels the data can be split in step 1110 by the expiry time predictor 216 between the training data set 1112 and the test dataset 1116. The training data set 1112 can be used to train the expiry time classifier model using supervised machine learning algorithms like Support Vector Machine, Random Forest and so on in step 1114. The test dataset 1116 can be used to test and validate the performance of the expiry time classifier model in step 1118. This process repeated until an expiry time model with satisfactory performance is determined (step 1120).

Threats are reported from multiple different data sources 200-204. Although the threats are reported from three different data sources, any number of data sources can be used. The threats reported by the data sources 200-204 can be buffered in the scalable queue 222a. The threats of the data sources 200-204 are shown as different shapes to represent different threats. The circle threats reported by the data sources 200-204 each represent the same incident. Similarly the start shaped threats reported by the data sources 200 and 202 represent the same threat and likewise the triangle threats reported by the data sources 202 and 204 represents the same threat.
The cross-correlator 220 is shown to include an event processor 1310. The event processor 1310 can be configured to read the threats from the scalable queue 222a and processes the incoming threats in real-time and store them in scalable queue 222b. The event processor 1310 can be configured to implement an instance of in-memory cache to store the most recent threats. The cache provides high speed lookups and read/write capability which is required to be able to processes thousands of incoming threats reported from all the data sources. The windows of time to keep the threats in the cache can be configurable. In some embodiments, the window can be six hours of time.
The event processor 1310 can be configured to group threats together based on information of each of the threats. For example, the event processor 1310 can be configured to analyze a time that each threat was reported, a location of each threat, and a category of each threat to determine whether to group threats together or not. If all the time, location, and/or category match any of the cached threats, those threats can be grouped with the cached threats.
For the time and location a certain amount of tolerance is defined (e.g., threats with a timestamp falling within a predefined length of time from each other can be considered occurring at the same time). The tolerances can be different for different data sources 200-204, different for different types of threats, and/or based on the particular implementation of the cross-correlator 220. The event processor 1310 can implement a threat-specific tolerance for time and location. For example weather related threats may have a higher tolerance than traffic incidents. An earthquake might be reported by multiple sources more than a mile difference in the location. However, an urban traffic incident should have much less than quarter of a mile in difference.

In step 1410, the connector 1402 can receive new threats from the data sources 200-204 and forward the new threats to an event hub 1404. The event hub 1404 can provide the new threats to the event processor 1310 in step 1412. The event processor 1310 can identify, in step 1414, a type of each of the threats. The threats received by the event processor 1310 may be standard threats that have been processed by the data ingestion service 116 and can include an indication of the identity of each of the threats.
In step 1416, the event processor 1310 can store the threats in the cache 1408. Particularly, the event processor 1310 can store a first threat of the first data source 200 in the cache 1408. In step 1418, the event processor 1310 can retrieve the first threat from the cache 1408. The step 1418 can be performed periodically and/or in response to receiving a second threat from the second data source 202. In step 1420, the event processor 1310 can compare the second threat with the first threat to determine if there is an association, i.e., both threats describe the same incident. The event processor 1310 can determine whether both threats describe the same threat type. The association can be determined by analyzing a time of occurrence of each threat. The event processor 1310 can determine whether the threats occur within a predefined length of time from each other. The length of the predefined time can be dependent on the type of threats of each of the threats.
Furthermore, the event processor 1310 can analyze the location of the threats. If the threats have a reported location that is within a predefined distance from each other, the threats can be considered to have occurred at the same location. For example, the predefined distance can be a half mile, a mile, ten miles, etc. The distance can be different for different types of threats. In response to determining that the type, time, and/or location of the first threat and the second threat are the same, the event processor 1310 can determine that the threats are the same threat and should be associated and grouped.
In step 1422, the event processor 1310 can group the threats together into a single threat. The grouped threats can be added back into the cache 1408 and/or forwarded on to other components of the system 106, e.g., the geofence service 118 in step 1426. The grouped threats can be again compared to new threats so that two or more threats can be grouped together. In step 1424, cached threats can be dropped after a set period of time occurs and the cache memory can be set to free memory. In some embodiments, each of the threats has an expiry time or otherwise there is a set expiry time for the cache 1408. In response to the time occurring, the threat can be dropped from the queue.

The geofence settings can be different for each asset for different threats. Some threats are considered “far” if the distance between the threat and the asset is more than 10 miles and some other threats to be considered “far” that setting might be 40 miles for example. Natural disasters usually have much larger range of impact than minor urban incidents. That is why the geo-fences defined for assets can be per threat type.
Referring now to
In step 1504, the geofence service 118 can retrieve a geofence for each of a collection of assets based on the threat. The geofence service 118 may store, or otherwise retrieve from a different data store, a particular geofence for each of multiple assets. The geofence may be particular to both the threat and the asset itself. For example, the geofence may be a particular size and/or geometric based on a severity of the threat, a type of the threat, a type of the asset, and/or a vulnerability of the asset to the particular threat. The geofence may be a particular geographic boundary surrounding each of the assets.
In step 1506, the geofence service 118 can determine whether a geofence of each of the assets is violated by a location of the threat. Since the threat can include an indication of location, the geofence service 118 can determine whether each of the geofences of the assets is violated by the location of the asset, i.e., whether the location of the threat is within the geofence of each of the assets. The result of step 1506, the determination whether each of the asset geofences are violated by the threat, can cause the geofence service 118 to perform steps 1508-1516 for each of the assets.
Considering a particular asset, if, in step 1508, there is a determination by the geofence service 118 (step 1506) that the threat violates the geofence of the particular asset, the process moves to step 1510. If the geofence of the particular asset is not violated by the threat, the process moves to step 1518. In step 1518, the geofence service 118 stores the threat. Storing the threat can include, causing, by the geofence service 118, the threats service 122 to store the threat in the threat database 124. The geofence service 118 may only perform the step 1518 if none of the assets have a geofence violated by the threat.
In step 1510, the geofence service 118 can determine the number of geofences of assets that are violated by the threat. If, more than one asset has a geofence violated by the threat, step 1512, the geofence service 118 can perform step 1415. If only one asset is associated with a geofence that has been violated, the process can proceed to the step 1516.
In step 1514, the geofence service 118 can generate separate threats for each of the assets that have a geofence violated by the threat. For example, each of the threats can be paired with a particular asset to form an asset-threat pairing. In step 1516, the geofence service 118 can send all the threats, either original or generated in the step 1514, to the RAP 120.

Threat 1612 is shown to violate the geofences 1618, 1620, and 1616. In this regard, the geofence service 118 can replicate the threat 1612 so that there is a corresponding threat for each of the assets 1602, 1604, and 1606. Furthermore, the threat 1610 is shown to violate a single geofence, the geofence 1614 but no other geofences. In this regard, the geofence service 118 does not need to replicate the threat 1610 but can pair the threat 1610 with the asset 1608.
In some embodiments, the threats 1612 and/or 1610 can be associated with their own geofences. The geofences can be included within the threats 1612 and/or 1610 and can be extracted by the geofence service 118. In some embodiments, the geofence service 118 can generate the geofences for the threats 1612 and/or 1610 based on a severity of the threat and/or a type of the threat. The geofence service 118 can determine what asset geofences intersect with the threat geofences. The area of intersection can be determine by the geofence service 118 and used to determine whether the asset is affected by the threat and/or whether the severity of the threat should be adjusted for the threat. In some embodiments, if the intersection area is greater than a predefined amount (e.g., zero), the threat can be considered to violate the geofence. However, based on the area of the intersection, the severity of the geofence can be adjusted. For example, particular areas can be associated with particular severity levels and/or particular adjustments to an existing severity level so that the severity level of a threat can be tailored specifically to each of the assets associated with geofences that the threat violates.

The risk engine 310 of the RAP 120 can be configured to generate risk scores for the threats via a model. The model used by the risk engine 310 can be based on Expected Utility Theory and formulated as an extended version of a Threat, Vulnerability and Cost (TVC) model. The risk engine 310 can be configured to determine the risk scores on a per asset basis. The threats can all be decoupled per asset in the processing pipeline as well as the calculation of the risk. For example, if a protest or weather condition is created alerts towards multiple buildings, separate alerts per building will be generated based on the geo-fences of the building and the detected alert. This will insure that the RAP 120 can horizontally scale as the threats are introduced to the system. The model used by the risk engine 310 can be,
where, Ti(t) is the probablity of threat or attack threati at time t, Si is the severity of the threati at time t, Vi(threati, Asset) is the vulnerability index of that Asset against threat_i, CAsset is the cost or consequence of losing that asset, p≥1 is a positive value associated with the p-norm, and Di is the weight corresponding on the geographical proximity (distance) of the threat i to the asset. ρ(t) is the decay factor for the risk score.
There can be two sets of parameters in the formula for risk calculation. The first set of parameters can be from the threat and the second is about the asset impacted by that threat. The list of the threat categories can be different in different applications. But some of the most popular categories are Weather, Terrorism, Life/Safety, Access/Intrusion, Theft/Loss, Cybersecurity, and Facility. The model is not limited to specific type of threats and can be updated as new sources of threats are introduced. There are certain threat parameters that play an important role on the level of risk they potentially impose on the assets.
Severity of the threat refers to the intensity of reported incidents independent of the impact on assets. Notice that other measures like geographical distance will play a role on the risk besides the severity. However, severity is focused on the intensity of the threat itself. For example in case of a hurricane its severity can be measured by the category level of the hurricane. It might not even be a major risk if it is too far from assets or if the assets are tightened with protective measures.
One of the parameters in the threat is the probability of actually threat occurring (Ti(t)). This topic brings us to the concept of predictive and reactive risk. If the time in the risk formulation refers to a future time, that risk is considered to be predictive. To be able to estimate or predict the risks in a future time, the system 106 should be configured to predict the parameters involved in the calculation specially the potential threats and their severity in a future time. Some data sources that report the threats include threats that are expected to happen in future. Threats like planned protests, threats of violence or attacks and so on fall under the category of predictive risk. Those predictive threats will be used to train ML models to estimate the validity of the threats. On the other hand, the threats that have already happened and reported fall under reactive risk.

The matrix will include all the threats that are supported in the system. VT matrix will be a n×m matrix for, m assets exposed to n different threats. The values can be between 0-1 showing no vulnerability to full vulnerability. In some embodiments this can be further simplified to a binary matrix considering only values of 0 and 1. But, in some other embodiments any range between [0, 1] can be applied.
Regardless of the imminent threat and its nature, the value of the asset is important in evaluating the risk to the owner. The asset value becomes more important when a company has multiple types of assets with different functionality and responsibilities. Some of them might be strategic and very valuable. But, others might be smaller and less valuable compared to the others. Asset assessment includes the asset cost estimation besides vulnerability assessment. The result of the asset value assessment is translated to a number between 1 to 10 in the risk model to represent the least to most valuable assets.
In any given point in time an asset might be exposed to multiple threats. There might be heavy rain and major traffic accidents at the same time. To be able to combine the effect of the threats the formulation includes a p-norm to combine the threats. p could be any positive integer in the formula. Here, 2 and infinity are considered as possible values. 2-norm might not be a good metric for analyzing the multiple sources of threats since it will decrease the impact of the highest threats. ∞-norm can be a good or the best option, since it focuses on the highest degree of the risk.
The calculated risk can corresponding to dynamic risk score. The risk score can gradually decay until the threats are expired. ρ(t) can be the decay factor that is multiplied to the risk score based on a decay model.

The risk engine 310 is shown to include a TVC model 1816. The TVC model 1816 can be the TVC model as shown and described above. The risk engine 310 can expose the TVC model 1816 to the outside world via an API. The API can be a REST API. The API can provide four endpoints; a risk score endpoint 1808, a threat list endpoint 1810, a VT matrix retrieve endpoint 1812, and a VT matrix update endpoint 1814.
The risk score endpoint 1808 can be an endpoint used to return the risk score for the incoming threats. At this stage of the pipeline the threats are identified to be at the vicinity of at least one of the assets and also they are enriched with the asset details. The threat list endpoint 1810 can retrieve the list of all the threats that are recognized by the risk engine. The list is the master list of all the threats from all the data sources that report threats to the system. The VT matrix endpoints can be two endpoints here to retrieve and modify the VT matrix settings. The risk engine 310 is shown to include a threat list 1818 and a VT matrix 1700. The threat list 1818 can be a list of all the threats that the risk engine 310 needs to processes. The VT matrix 1700 can be a matrix of the vulnerability parameters for specific threats, e.g., as shown in

Furthermore, the systems and methods discussed herein can be configured to analyze historical data to determine if there is a weather related condition occurring that would not normally occur. A facility or city may not be prepared to respond to an extreme weather related condition if the extreme weather related condition rarely occurs at the facility. The systems and methods could determine whether a weather condition is abnormal based on analyzing historical data (e.g., historic temperature ranges, snow fall amounts, etc.) for a predefined amount of time in the past (e.g., the past five years). If the weather condition is abnormal, a risk score can be generated based on the abnormal weather condition such that the value of the risk score is increased due to the abnormality of the weather condition. For example, if it has not snowed in Atlanta in the month of October in past 5 years, and suddenly for a particular year it does snow in Atlanta in October, the systems and methods described herein could generate an increased risk score for the snow fall since the city of Atlanta may not have the infrastructure (e.g., snow plows, response personnel, etc.) to handle the snow fall.
Furthermore, weather data can be enriched or cross-correlated with non-weather related events. For example, if there is a major event at a building (e.g., a party, a large meeting, etc.) and there is a high snow fall, a risk score for the building or and occupants of the event can be compounded to account for additional dangers which may occur due to the high population being subjected to the weather event.

The standard threats received from the geofence service 118 can be threats originally generated by the data sources data sources 102 and can be weather threats such as high or low temperature, a hurricane, a tornado, a snow storm, etc. and/or any other threat e.g., a riot, a protest, etc. The data sources 102 can be a weather service data source (e.g., Accuweather).
In some embodiments, the data received by the RAP 120 is not directly a threat event. In some embodiments, the weather threat generator 1822 can analyze weather data to generate weather threat event. For example, the weather threat generator 2208 can determine if a temperature of received weather data is above or below predefined amounts (e.g., above 130 degrees Fahrenheit or below 40 degrees Fahrenheit or 0 degrees Fahrenheit). This may be indicative of an extreme temperature condition and the weather threat generator 2208 can generate a weather threat event. Similarly, if wind speed is above or below predefined amounts, an extreme wind speed threat event can be generated by the weather threat generator 1822. For example, if wind speed is above 30 or 40 miles per hour, an extreme high wind speed threat event can be generated. Similarly, if an air quality metric (e.g., an AQI) for a city or area is worse than (e.g., above) a predefined amount, an extreme high air quality index threat event can be generated.
The weather threat generator 1822 can be configured to analyze the weather threat event data and update parameters of the parameters 1826 based on the received data via a weather parameter updater 1824. The weather parameter updater 1824 can be configured to analyze one or multiple weather related threats together to determine whether one threat event increases the severity of another threat event. For example, if one threat event indicates that there is heavy snow precipitation and another threat event indicates that there are extremely low temperatures, a particular building asset (e.g., a person, a building, etc.) may be at a high risk. Therefore, the weather service 1820 can increase a risk score of an asset by increasing the threat severity parameter 1834 so that the threat severity of the heavy precipitation increases to account for both heavy snow and extremely low temperatures.
The weather parameter updater 1824 can be configured to correlate various extreme weather related conditions together to determine whether the risk score should be compounded based on the presence of multiple extreme weather conditions. For example, if there is high temperature and/or high humidity in addition to poor air quality, a high temperature threat event may have an increased risk score since the high humidity and/or poor air quality can increase the danger of the high temperature. Based on combinations of extreme weather conditions, the parameters 1826, specifically the threat severity 1834 can be adjusted so that the risk score generated by the risk engine 310 is increased (e.g., compounded) based on the presence of multiple threat events indicating extreme weather conditions.
The risk engine 310 can, for each of multiple assets, be configured to generate a risk score with the TVC model 1816. The risk engine 310 can be configured to generate a risk score for the asset based on multiple simultaneously occurring threat events. For each threat event for the asset, the risk engine 310 can be configured to generate a set of risk scores. The risk score enricher 312 can be configured to select the risk score with the highest value from the set of risk scores and use the highest valued risk score as the asset risk score. The asset risk score can be provided to the risk applications 126 for presentation to an end user. Based on the TVC model 1816 and parameters 1826, a risk score for each threat event of a particular asset can be determined.
In some embodiments, the RAP 120 can be configured to analyze risk scores or other received data over a period of time (e.g., a year) to identify trends in the asset risk scores, identify anomalies in the trends, generate a new alarm (e.g., a synthetic event), determine risk scores averaging, and/or perform risk score forecasting (e.g., predictions). Examples of analyzed risk scores are shown in

One rule for the weather correlation rules 1838 may be that for a high temperature threat event associated with a score above a predefined amount and a poor air quality threat event with a risk score above a predefined amount, a final risk score should be generated as a function of both risk scores since high temperature and poor air quality may result in a dangerous situation. An example of a determination for a final risk score based on two threat events for poor air quality and high temperature may be,
Final Risk Score=θ1AssetRiskScoreHigh Temperature+θ2AssetRiskScorePoor Air Quality
where θ1 and θ2 may be multipliers for determining that risk score based on two separate risk scores. For example, if the high temperature risk score is 70 and the poor air quality risk score is 52 and the weighting parameters θ1 and θ2 are 0.8 and 0.6 respectively, a final risk score could be determined based on,
Final Risk Score=(0.8)(70)+(0.6)(52)=87.2
Each weighting parameter may be predefined such that combinations of weather threat events result in particular final risk score values. A generalized equation for weighting risk scores together may be,
In other embodiments, the risk score may be determined by applying a multiplier to a greatest of the component risk scores. For example, in the example above, where the high temperature risk score is 70 and the poor air quality risk score is 52, the overall risk score for the asset may be determined by applying a multiplier (e.g., 1.2) to the highest component score of 70, which may, for example, result in an overall risk score of 84.

The weather threat analyzer 1836 can be configured to store risk scores generated by the risk engine 310 in a historical weather database 1838. The historical weather database 1838 may store days, months, years, and/or decades of risk score data. The historical weather database 1838 can be configured to store historical data for generated risk scores for high temperature threat events, risk scores for low temperature threat events, risk scores for tornados, hurricanes, etc. The historical weather database 1838 may indicate the frequency at which particular weather related threat events occur and their severity (e.g., their risk score for particular assets). Furthermore, the historical weather database 1838 can be configured to store raw environmental data. For example, the historical weather database 1838 could store an indication of every snow fall in the past ten years and the amount of snow for each snow fall. Furthermore, the historical weather database 1838 can be configured to store temperature trends over the past two decades.
The weather threat analyzer 1836 can be configured to generate the normal weather rules 1840 based on the historical threat events and/or the raw environmental data stored by the historical weather database 1838. The weather threat analyzer 1836 can be configured to implement various forms of machine learning, e.g., neural networks, decision trees, regressions, Bayesian models, etc. to determine what a normal threat event risk score would be for a particular threat event (e.g., a risk score range), a normal environmental condition (e.g., an environmental condition range), or other rules for identify abnormal environmental conditions.
Based on the normal weather rules 1840, the weather threat analyzer 1836 can compare new risk scores for threat events to the normal weather rules 1840. For example, if a high temperature risk score is normally between 30-40 but a new risk score is at 70, this may indicate that a substantially higher temperature than usually encountered by an asset is present. In this regard, the weather threat analyzer 1836 can increase the final risk score to account for the fact that the asset may be experiencing a weather related threat event that it is not prepared to endure. For example, for an area where tornados are not usually present, a threat event for a tornado may be 170. However, if based on the frequency of tornado threat events and risk scores associated tornados the weather threat analyzer 1836 identifies a threat event risk score range of 100-150, the weather threat analyzer 1836 may multiply the tornado threat event risk score by a multiplier to increase the value for the tornado threat event.
As another example, a weather threat event may be for a temperature at a particular high value for a day, e.g., for 100 degrees Fahrenheit. The normal weather rules 2404 may indicate that normal temperatures for a city are between 30 degrees Fahrenheit and 70 degrees Fahrenheit. The threat event of 100 degrees Fahrenheit may be outside the range and, thus, may be an anomalous weather threat event.
In some embodiments, the multiplier may be selected based on a frequency or value of the threat event. For example, a threat event may occur at a rate of 0.1%. The lower that threat event rate, the higher the multiplier may be. Furthermore, if the threat event corresponds to a value range, for example, temperature between 80 and 100 degrees Fahrenheit is normal during summer months, a multiplier may be selected based on how high above the temperature range a current threat event is associated with.

In step 1844, the RAP 120 and/or the data ingestion service 116 can receive weather threat data from a data source. The RAP 120 can receive weather threat data from the local or third party data sources (e.g., 102) or can receive processed threats from the geofence service 118 originally received and processed by the data ingestion service 116 and/or the geofence service 118.
In step 1846, the RAP 120, the data ingestion service 116, and/or the geofence service 118 can generate multiple weather threat events based on the received data of the step 1846. In some embodiments, the received data is raw data, e.g., temperatures, wind speeds, etc. In some embodiments, the received data is a threat event. In some embodiments, the RAP 120, the data ingestion service 116, and/or the geofence service 118 can generate one or more weather threat events and one or more non-weather threat events based on the received data of the step 1844. For example, in some embodiments, the RAP 120, the data ingestion service 116, and/or the geofence service 118 can generate one threat event based on high temperatures and another threat event based on an unusually large population in or near a building or site, such as due to a conference or other gathering.
In the step 1848, the RAP 120 can generate risk scores for a particular building asset (e.g., a building, a geographic area, an occupant of the building, equipment within the building, etc.). The risk scores may be a risk score for a particular asset determined based on each of the threat events received in the step 1844 or determined in the step 1846. In this regard, if there is a high snowfall threat event and a low temperature threat event, two separate risk scores can be determined each for the two threat events. Similarly, if there is a high temperature threat event and large population threat event, two separate risk scores can be determined for those events.
In the step 1850, the RAP 120 can determine a final risk score for the building asset based on the risk scores determined in the step 1848 and based on weather threat correlation rules. The correlation rules may be the weather correlation rules 1838. The correlation rules 1838 may indicate that particular weather related threat events should have combined risk scores since both of the weather threat events together may indicate a situation more dangerous that the weather threat events on their own. The correlation rules may indicate a particular weighting factors such that a final risk score can be generated based on the values of the correlated weather related threats.
For example, in the step 2508, for multiple threat events, the analytics service 628 can use the Equation 6 to generate a final risk score. In some embodiments, the analytics service 628 can use the weather correlation rules 2304 to determine a final risk score based on one or more weather threat events and one or more non-weather threat events. For example, in some implementations, the analytics service 628 can determine a final risk score based on a first risk score for a high temperature threat event and a second risk score for a large population threat event, where the weather correlation rules 2304 may indicate that the final risk score should be higher than the individual risk scores due to the combination of the high temperature and the larger than normal population leading to a higher level of risk.
In step 1852, the RAP 120 can provide the final risk score to a user interface e.g., the risk applications 126. In some embodiments, the risk score can be provided and displayed in the user interface described with reference to

In step 1858, the RAP 120 can receive a first set of weather data. The received first set of weather data can be weather threat events, ambient temperatures, humidity values, air quality values, etc. In some embodiments, the stored data includes risk scores for various weather threat events that have occurred over a past decade. This first set of data can be stored in the historical weather database 1338 in step 2604. Over time, the analytics service 628 can collect and store the data in the historical weather database, i.e., perform the steps 2402 and 2604 iteratively for days, months, years, decades, etc.
In step 1862, based on the receive historical data, the RAP 120 can generate normal weather rules (e.g., the normal weather rules 1840). The normal weather rules may indicate the normal weather conditions of a particular area. The rules may be a temperature range, a snowfall amount range, etc. Furthermore, the ranges can be risk score ranges of the normal value of a risk score for a particular weather threat event. If a winter temperature is between 50 degrees Fahrenheit and 65 degrees Fahrenheit, a temperature of a threat event for 5 degrees Fahrenheit may indicate an abnormally cold threat event. Furthermore, the rules may indicate risk score ranges for various weather threat events. For example, air quality risk scores for air quality threat events may be risk scores between 30 and 40. An air quality risk score outside of the risk score range may indicate that an abnormal air quality condition is present.
In step 1864, the RAP 120 can receive a second set of weather threat data from the data source. The second set of weather threat data may be current threat data for the data source. In step 2610, the analytics service 628 can generate an asset risk score based on the received second set of data. The analytics service 628 can generate the risk score based on the building asset risk model 1812.
In step 1868, the RAP 120 can generate a final asset risk score based on comparing the value of the asset risk score determined in the step 1864 to the normal weather rules generated in the step 1862. If the rules indicate that the weather threat event is abnormal, e.g., outside a usual temperature range, is a threat event that rarely occurs, etc., the RAP 120 can increase the asset risk score. In some embodiments, a multiplier is chosen or retrieved for increasing the risk score. The multiplier can be multiplied with the risk score to generate the final risk score.
In some embodiments, the multiplier is dynamic, i.e., based on the threat event, a multiplier can be generated and utilized to increase the risk score. For example, the frequency at which a threat event occurs (e.g., of the threat event rules), can determine the multiplier. A threat event that occurs less than a predefined amount may be associated with a first multiplier. The process 1856 can proceed to 1870 and/or 1872, both of which are described with further reference to

The interface 1900 includes selections to update the VT matrix 1700 in bulk and/or for a single asset via selecting option 1910. The interface 1900 includes a select asset category dropdown 1902. The dropdown 1902 allows a user to select all assets of a particular category. “Tactical” is shown as the selected category but any other category “Human,” “HVAC Equipment,” and/or any other category can be included in the dropdown 1902.
If the user is operating in a “Single Update” mode, particular assets can be selected via dropdown 1904. The assets in the dropdown 1904 can be numbered with an identifier, e.g., “1,” “2,” etc. and/or with a name “Building Lobby,” “Grand Hotel,” and/or any other asset. Particular threat categories can be enabled for an asset and/or group of assets. For example, dropdown 1906 can provide a user with a list of threat categories that are enabled for asset and/or asset group. A “Disease Outbreak” threat category is shown but any other type of threat “Shooting,” “Rain,” “Flooding,” etc. can be included in the list. If the user interacts with the button 1912, the selected threat from the list can be disabled and removed from the list.
The dropdown 1908 can allow a user to view threat categories (threat categories not already in the dropdown 1906) to the dropdown 1908. If a user selects a particular threat category via the dropdown 1908 and interacts with the button 1914, the threat category can be added to the list of threats that the asset and/or assets are vulnerable to, e.g., the selected threat is added to the dropdown 1906.
The user can enter a particular value for a threat and/or asset vulnerability. In response to interacting with the button 1916, the group of assets selected via the interface 1900 can be updated with the entered value. If the user interacts with the button 1918, the particular singular asset selected by the user via the interface 1900 can be updated. Based on the selection via option 1910, the button 1916 and/or 1918 can be enabled and/or disabled to be interacted with (in bulk update mode the button 1916 can be enabled while in single update mode the button 1918 can be updated).

The stream processing steps can update risk score in real-time. After the threats are identified to be at the vicinity of an asset by the geofence service 118 they are enriched with the asset information. The RAP 120 can check to make sure the threat is not expired by checking the current time and the expected expiry time. If the event is expired it will be persisted to the database. If it is not expired then it will be sent to the risk engine along with all the other active threats for that specific asset to generate a risk score. The generated risk score will be pushed to the real-time risk score topic 2020 to be consumed by the monitoring client 128 and the risk dashboard 130. It will also be persisted to the database of historical risk scores.
The batch processing steps for risk decay and threat expiry can be handled by a set of batch processes. The batch processes may be a continuously running process that wakes up at a predefined interval (e.g., every 10 minutes) and retrieve all the assets from the database. Then for each asset all the active threats are queried. Active threats are the threats with status set to “open”. The database used within the risk analytics pipeline stores the threats after the threats have been enriched after the geofence service 118 and asset service 304 call. Therefore the threats are stored with asset information and also one threat per asset at a time. The current time will be compared with the expiry time predicted value. If the current time exceeds the predicted expiration time then the threat will be considered to be expired. The expired threat then can be pushed to the database for storage. If the threat is not expired the risk score from that threat can be decayed. This can be done by loading the right decay model (polynomial function for example) and calculating the decay factor from the equations as described with reference to
The risk score then can be multiplied by the decay factor. This will repeat for all the active threats for that specific asset and then the highest risk score will be selected as the risk score for that specific asset. This process can repeat for all the assets until all the risk scores are updated. The updated risk scores cab be pushed to a real-time risk score topic (e.g., a Kafka topic) from which the monitoring client 128 and the risk dashboard 130 fetch the risk score updates.
Baseline risk score is another batch processes that updates the baseline risk every particular interval (e.g., every ten minutes). The baseline risk score can be calculated by aggregating all the risk scores generated for that asset over the historical period (the longer the better). The aggregate scores will be grouped per category and those scores will be pushed to the historical/baseline topic to be consumed by the applications.

In step 2004, the RAP 120 can retrieve all assets from the asset database 306. The assets can be all assets currently stored in the asset database 306. In step 2006, based on the retrieved assets, threats for each of the retrieved assets can be retrieved by the RAP 120. For example, the threats may be stored in the risk database 314 and thus the RAP 120 can retrieve the threats for each asset from the risk database 314. In some embodiments, only threats marked as “active” are retrieved by the RAP 120.
In step 2008, the RAP 120 can determine whether each of the active threats retrieved in the step 2006 are expired. Each of the threats retrieved in the step 2006 may be marked as active or closed. If the threat is marked as active, the RAP 120 can determine if an expiry time associated with the threat has passed. In step 2010, if the expiry time has passed as determined in the step 2008, the process can continue to step 2022 but if the expiry time has not passed, the process can continue to step 2012.
In step 2012, the RAP 120 can load a decay model for the threats retrieved and determined to not be expired in the steps 2006-2010. The decay model can be specific to each of the threats and/or for each of the assets. In this regard, for a particular combination of a threat and an asset, a specific decay model can be selected. In this regard, the appropriate decay, modeling the response to an incident, for a particular threat affecting a particular asset can be modeled.
In step 2014, based on the loaded decay models, decay factors can be determined for the threats by the RAP 120. In step 2016, the decay factors can be multiplied by the RAP 120 against the risk score of the threats to generate a decayed risk score. In some embodiments, where a particular asset is associated with multiple different threats, a risk score can be determined and/or decayed for that asset. The RAP 120 can compare the multiple risk scores against each other for the asset and select the highest risk score in the step 2018. The highest risk score selected in the step 2018 can be set to the real-time risk score topic and the risk applications 126 (the monitoring client 128 and/or the risk dashboard 130) can read the real-time risk score topic 2020 to retrieve the highest risk score for a particular asset and cause the highest risk score to be displayed in a user interface.
If one or multiple threats have expired, determined in the steps 2008-2010, the RAP 120 can update the status of the threat to “closed” to indicate that the threat is no longer active in step 2022. In step 2024, the threat database 124 can be updated by a threat database (e.g., the threat database 124) to include the new “closed” statuses for the threats that have been determined to have been expired.
In step 2025, the RAP 120 can receive a new threat from one of the data sources 102. Since the threat may be new, the step 2026, 2028, and/or 2030 can be performed as stream processing, i.e., in response to receiving the new threat. Since the new threat may be associated with an expiration time, the RAP 120 can determine, based on the expiration time, whether the new threat has already expired. In response to determining that the new threat has already expired, the process can proceed to the step 2024. In response to determining that the new threat has not yet expired, the process can move to the step 2028.
In step 2028, the RAP 120 can retrieve all other active threats for the asset affected by the new threat. In step 2030, based on the new threat and/or all the other active threats retrieved in the step 2028, the RAP 120 can determine a risk score for the asset by calling the risk engine 310 to determine the risk score for the new threat (or the other active threats retrieve din the step 2028). The RAP 120 can compare the score of the new threat and the other threat scores and select the highest score to be the score for the asset.
In step 2032, the RAP 120 can update a historical database of risk scores for the asset. The historical database of risk scores can indicate risk scores for the asset for a particular time and/or for particular times over an interval (e.g., a window of time). In step 2034, the historical risk scores of the historical database can be used to calculate a baseline risk score. The baseline risk score can be generated by averaging risk scores over a particular time period, the risk scores retrieved from the historical database. The result of the calculation of the step 2034 may be the baseline risk 334. The baseline risk 334 can be saved as an endpoint that the risk applications 126 can query to retrieve the baseline risk 334 and present the baseline risk 334 to a user via the monitoring client 128 and/or the risk dashboard 130.

As shown in the chart 2100, the threat risk scores 2102-2106 have a beginning time and an expiration time. However, the value for each of the threat risk scores 2102-2106 ends suddenly; there is no decay of the score. In many instances, setting the risk score to zero for one of the threat risk scores 2102-2106 does not properly model an incident since the risk score associated with the incident may decrease over time. In this regard, the risk decay as described elsewhere herein can be applied to the risk scores to more accurately model how risk behaviors and incidents are responded to and resolved. Chart 2200 provides an example of risk decaying over time.
There is not information about the decay if focus is put on the two states of a threat “open” and “closed”. An analyst will have no expectation on how long a threat is going to last until suddenly the score goes down. But with risk decay, the score goes down gradually according to the expiry time predicted by a machine learning model developed on the historical data and thus the analyst has an idea of how long the risk is expected to last.
In chart 2200, three threat risk scores 2202-2206 are shown where a risk score is decayed over time. The threats are the same as the threat risk scores 2102-2106 of chart 2100 but the risk is decayed with a decay model. The threats 2202 and 2204 are decayed with a polynomial decay model while the threat 2206 is decayed with an exponential risk model. The different threats can be decayed with different models based on a combination of the particular asset and/or the particular threat. Since the threat risk scores 2202-2206 are decayed over time, the asset sum risk 2212, which is a summation of all risk scores, is shown to also be decayed while the asset peak risk score 2210, which is the highest current decayed risk, is also decayed since it is based on the decayed risk scores 2202-2206. The baseline 2208 is shown to be the same as the baseline 2110 since the baselines can be determined based on the raw risk values, not the decayed risk values. In some embodiments, the baseline risk score is based on the decayed risk values.

The polynomial decay function, as shown in
The polynomial decay function parameters can be determined from Theorem 1.
Theorem 1 (Polynomial Risk Decay Function)Given a quartic function with a degree-4 polynomial for the decay model,
f(x)=a4x4+a3x3+a2x2+a1x+a0
the polynomial coefficients for a quarterly interpolation points of [1, 0.95, 0.80, 0.60, 0.05] can be uniquely calculated as,
a0=1
a1=0.4167α−1
a2=−3.767α−2
a3=6.133α−3
a4=−3.73α−4
where α is a positive real number representing the expected expiry time of the threat in minutes.

Element 2506 of the interface 2500 provides information pertaining to the asset affected by the threat described in the element 2504. The asset affected by the threat in this example is a retail building. The retail building is shown on a map interface along with a distance of the building from the threat, a name of the building, and an address of the building. The map illustrates both the location of the threat and the location of the building. Furthermore, a navigation route from the building of the threat is provided.
In
Element 2602 provides a dynamic risk score for the building affected by the threat, an indication of a number of threats currently affecting the building, and an element to view additional details regarding the building. Element 2608 provides a floor plan indication of the building affected by the threat of element 2606. The user can view each of the floors of the building and view, on the floor plan map, where the threat is occurring within the building. The element 2604 provides an indication of a dynamic risk score for the building an a tabulation of each of the threats affecting the building, for example, if another threat is affecting the building outside of the “Foil Break Alarm,” an active shooter threat, the active shooter threat and/or the foil break alarm can be shown in the element 2604 along with an indication of the risk score value for the particular threat. Element 2610 provides an indication of security camera feeds associated with the building at a particular location associated with the location of the threat occurring within the building. For example, the monitoring client 128 can be configured to identify, based on equipment reporting the foil break alarm, what camera in the building views the equipment and/or space associated with the equipment. In this regard, a user can view a live stream and/or a historical video stream (associated with the time at which the threat was triggered) to review the threat.

The risk card 2502 includes the most critical information but in a concise and brief manner. The risk card 2502 includes the dynamic risk score which corresponds to the current risk score from real time active threats. Then it also includes baseline risk score which shows the risk score over an extended period of time. Combination of these two together makes it a meaningful insight. Neither of them alone may be enough. Considering a location such as Miami, the risk of Tornado is higher in Miami as compared to Milwaukee but if one looks into the dynamic risk score which comes from the active threats reflecting what is happening “right now” that might not even show any difference because tornados do not happen any minute. However, if one looks into base risk score which has been calculated over 50 years of data then one would see that there is a noticeable difference in those scores between those cities.
On the other hand dynamic risk score is beneficial for situational awareness to understand what threats are active at the moment and which one has the highest risk. So the risk card shows both base and dynamic risk score. It also shows the slope (rise or fall) on the last hour for dynamic risk to show where it's headed.
The risk card 2502 includes two categories for base risk score: Crime and Natural disaster. Those are the two main categories that many users care about according to some studies. The baseline risk scores for crime and natural disaster when combined might convey wrong information. In this regard, baseline risk scores can be determined for particular categories so that a user can compare a dynamic risk score for crime to the baseline for crime and a dynamic risk score for natural disasters to the baseline for natural disasters.
Other than the risk card, an “alarm details” page can be viewed in response to interacting with the element 2708 which shows the more detailed info on that alarm or threat. In that page, additional information on the risk score is provided as well for example the distance of the threat and also the details of the asset that was impacted. In the detailed information page one can also show the base risk score at the sub-category level. For example if risk score is shown to be high for natural disaster at the risk card level, the interface can specify which sub-category e.g. earthquake, tornado snow fall and etc. on the detailed page.

Existing solutions may prioritize events and alarms by adding “severity” metadata fields to the monitored data. These severity fields are usually configured by the site-monitoring devices themselves. One disadvantage of these methods is the severity data's lack of situational context. For example, two identical “glass break” events in two different buildings may have different actual priorities if one of the buildings is near a civil demonstration. Similarly, the same category of asset threat would have a different actual impact on buildings of greater value, or where a senior executive, or a known offender, is present. In current solutions, such events are likely to be given equal priority without further investigation, adding potential cost and delay to the incident management process. An automated, more richly contextualized risk analysis of threat data facilitates a more timely and accurate prioritization of asset threats.
As another example, a broken window in a building could trigger a break glass alarm event. The risk score for the building asset would be increased in response to the event occurring. The risk score for the building may not trigger any automated workflow (e.g., call the police). However, if there is an event in the vicinity of the building, e.g., an active shooter, the building asset risk score could be elevated. The break glass event risk score could be added to the already elevated risk score to reflect the larger potential significance of the break glass event occurring near the active shooter. This could cause an automated workflow to be triggered causing security personal to be contacted or access to specific areas of the building to be restricted.
For an increase in the risk reported from social media on an specific asset, the priority of the alarm related to that asset movies higher on the monitoring client interfaces 2800-2900 because of the increased risk. This provides dynamic alarm prioritization in real-time versus statically prioritizing alarms without including any signals on the incidents that happen in real time that leave a potential risk on assets.
The provided risk score can also be used to sort the alarms based on the risk score. The risk score can be dynamic risk score for the most important alarm at that particular time or it can be the baseline risk score to highlight the assets or neighborhoods that historically have shown higher exposer to threats like crime or natural disasters.

The implementation of the risk dashboard 130 can be different in different applications. The risk dashboard 130 allows a user to view dynamic risk history, threats and asset information interactively. As shown in the figure, the threats can be categorized and filtered interactively to enable analyzing the risk globally across all assets. The threats can be filtered by asset category, threat severity, threat type, geographic regions, etc. Furthermore, the risk dashboard 130 (or any other risk dashboard described herein) can display forecasted risk for multiple future points in time based on multiple past threat values (e.g., for a particular asset). Risk scores can be forecasted via timeseries forecasting techniques such as the techniques as described in U.S. patent application Ser. No. 14/717,593 filed May 20, 2015, the entirety of which is incorporated by reference herein.
Referring more particularly to interface 3000, interface 3000 is shown to include an element 3002. The element 3002 can provide an indication of the most recent risk score for a particular asset for all assets reported in the interface 3000. Element 3004 can show the value of the risk score, an identification of an asset, a location of the asset, and time that the threat occurred that is affecting the asset. The risk information shown in the element 3004 can be the information of the last risk score shown in the element 3002.
A counter 3006 is shown in the interface 3000. The counter 3006 can count the number of threats that have been recorded for all assets on a global scale. An indication of a time at which the risk dashboard 130 most recently updated the counter 3006 can be shown. In some embodiments, the total number of threats shown by the counter 3006 is an all-time count and/or for a particular period of time into the past. The element 3008 can show a count of threats by data source. In this regard, the risk dashboard 130 can record the number of threats reported by teach of the data sources 102 and display the indication in the element 3008.
Element 3010 illustrates threats by geographic area on an interactive map. The asset locations shown may correspond to important cities and/or cities where assets belonging to the entity and/or entities are located. The risk scores for the assets can be shown by different colors to indicate the level of risk of each city. For example, some cities may have more risk scores and/or higher level risk scores, therefore, these cities can be assigned a different risk level and/or risk level color.
In element 3016, risk scores are shown over time. The risk scores can illustrate a trend for a particular asset, city, and/or a maximum reported risk score for multiple points of time. Element 3012 provides an indication of assets and the number of threats reported for particular locations (e.g., cities, states, countries, continents, etc.). Element 3014 provides an indication of a number of threats per category. The categories can be the same and/or similar to the categories described with reference to

Interface 3200 is shown to include element 3204. Element 3204 includes an indication of a number of threats received from the data sources 102 for each of the number of categories determines for the threats by the risk analytics system 106. The threat categories can be ordered in a list so that the categories with the highest number of threats is at the top and the categories with the lowest number of threats is at the bottom. If a particular category has more than a first predefined number of threats, the category can be shown in red text. If the number of threats for a category is between a second and the first number of threats (a range less than the number of threats for the red text), the threats can be shown in yellow. If the number of threats are less than and/or equal to the second number of threats, the threats can be shown in white. For example, for threat numbers are equal to and/or between 0 and 5, the categories can be shown in white. For threats equal to and/or between 6 and 11, the threat categories can be shown in yellow. For threat numbers equal and/or more than 12, the categories can be shown in red.
Elements 3206 and 3208 illustrate two threats and the assets that they each affect. The elements 3206 and 3208 are ordered based on the level of the risk that each represents. The elements 3206 and 3208 can be the same as and/or similar to the element 2504 as described with reference to
