Abstract

A security assessment tool can determine computer assets in a network and provide an overall security score for the network. The overall security score can represent an objective measure of the security of the network that considers potential security threats to the computer assets, counter measures deployed in the network to address the potential security threats, and the effectiveness of the counter measures. Based on the overall security assessment, the security assessment tool can provide recommendations for improving the security of the network.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is related to U.S. patent application Ser. No. ______ filed ______, entitled “SYSTEMS AND METHODS FOR DETERMINING AN OBJECTIVE SECURITY ASSESSMENT FOR A NETWORK OF ASSETS” by H D Moore, Roy Donald Hodgman, Dana Elizabeth Wolf, and Matthew Robert Hathaway, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

In today's distributed computing environments, security is of the utmost importance. Due to the rise of wide-area public networks, users have unlimited access to content, e.g. data, files, applications, programs, etc., from a variety of sources. Additionally, the users' connection to the public networks provides a window for malicious entities to attack the users' computing systems. Malicious entities utilize this ease of accessibility and anonymity to attack the users. For example, the malicious entities can plant viruses, Trojans, or other malicious agents in publicly available content in order to attack the users' computing systems and steal sensitive information from the users and can attack the users' system remotely across the public networks.

To identify security risks in computing systems and networks, users and administrators employ vulnerability assessment and security assessment tools. These tools can identify vulnerabilities in computing systems and networks but only provide discrete information about the vulnerabilities (i.e. that a vulnerability exists). Accordingly, the tools do not provide any assessment of the vulnerabilities within the context of the overall network security.

DETAILED DESCRIPTION

For simplicity and illustrative purposes, the principles of the present teachings are described by referring mainly to examples of various implementations thereof. However, one of ordinary skill in the art would readily recognize that the same principles are equally applicable to, and can be implemented in, all types of information and systems, and that any such variations do not depart from the true spirit and scope of the present teachings. Moreover, in the following detailed description, references are made to the accompanying figures, which illustrate specific examples of various implementations. Electrical, mechanical, logical and structural changes can be made to the examples of the various implementations without departing from the spirit and scope of the present teachings. The following detailed description is, therefore, not to be taken in a limiting sense and the scope of the present teachings is defined by the appended claims and their equivalents.

According to implementations, systems and methods are directed to providing an overall security assessment of a network of computer assets. In implementations, a security assessment tool can determine computer assets in a network and provide an overall security score for the network. The overall security score can represent an objective measure of the security of the network that considers potential security threats to the computer assets, counter measures deployed in the network to address the potential security threats, and the effectiveness of the counter measures. Based on the overall security assessment, the security assessment tool can provide recommendations for improving the security of the network.

FIGS. 1A and 1B illustrate an example of a network environment 100, in which a security assessment can be performed, according to various implementations. While FIGS. 1A and 1B illustrate various components contained in the network environment 100, FIGS. 1A and 1B illustrate one example of a network environment and additional components can be added and existing components can be removed.

As illustrated in FIG. 1A, the network environment 100 can represent the computer systems and network hardware of public or private entities, such as governmental agencies, individuals, businesses, partnerships, companies, corporations, etc., utilized to support the entities. The network environment 100 can include a number of computer assets 102. The computer assets 102 can be connected by one or more local area networks 104 and one or more wide area network 106. In implementations, a security assessment tool 108 can be configured to assess the security of the network environment 100 and provide an overall security score for the network environment 100.

The computer assets 102 can include any type of conventional computer systems that are operating with the network environment 100 or supporting the network environment 100. For example, the network environment 100 can include various types of servers, such as file servers, web servers, application servers, database servers, email servers and the like, that provide services within the network environment 100. Likewise, for example, the computer assets 102 can include laptop computers, desktop computers, tablet computers, mobile phones, and the like used by the personnel of the entities.

Additionally, for example, the computer assets 102 can include other hardware and computer systems that support the network environment 100. For example, the computer assets 102 can include gateways, routers, wireless access points, firewalls, and the like that support any type of communications networks, such as the local area network 104 and the wide area networks 106, to allow the computing systems in the network environment 100 to communicate. In any of the examples, the computer systems in the network environment 100 can include hardware resources, such as processors, memory, network hardware, storage devices, and the like, and software resources, such as operating systems (OS), application programs, and the like.

In addition to physical computer systems, the computer assets 102 can include virtualized computer systems, such as virtual machines (VM). A VM can be a virtualized computer system, or a software implementation of a computer system layered on top of any of physical computer system. The VM's access to the underlying computer system can be controlled through a hypervisor or virtual machine monitor. The VMs can provide for multiple and/or different operating system environments to run concurrently on a single computer system.

While several examples of the computer assets 102 have been described above, the computer assets 102 can include any system, whether physical or virtual, that performs computing processes in the network environment 100. Additionally, the computer assets 102 in the network environment 100 can be located at any location, whether located at single geographic location or remotely located from each other. For example, the network environment 100 can represent the computer assets 102 of a company that is located in multiple geographic locations. As such, one or more of the computer assets 102 can be located at one location (e.g. one office of the company) and one or more of the computer assets 102 can be located at one or more different locations (e.g. satellite offices of the company).

In implementations, the security assessment tool 108 can be configured to assess the overall security of the network environment 100. The security assessment tool 108 can be configured to identify the computer assets 102 of the network environment 100. Once identified, the security assessment tool 108 can be configured to determine the security information of the network environment 100 and the computer assets 102. Based on the security information, the security assessment tool 108 can be configured to determine potential security threats to the network environment 100 and the computer assets 102. Likewise, based on the security information, the security assessment tool 108 can be configured to determine counter measures that are deployed in the network environment 100 and deployed on the computer assets 102 to address the potential security threats. Based on the effectiveness of the deployed counter measures, the security assessment tool 108 can be configured to provide an overall assessment of the security of the network environment 100. Based on the overall security assessment, the security assessment tool 108 can be configured to provide recommendations for improving the security of the network environment 100.

As described herein, a security threat can be any process, method, technique, algorithm, condition, software program, policy, and the like that can be utilized to compromise the security of the network environment 100. For example, a security threat can include known threat vectors for computer assets 102 and the network environment 100, such as known malware, known exploits, known viruses, and the like. A counter measure can include processes, techniques, methods, algorithms, conditions, policies, software programs and the like that can be implemented in the network environment 100 to address potential security threats.

Security information can include any information about the structure of the network environment 100 and any information about the computer assets 102. For example, the security information can include security details of the network environment 100, such as security polices of the network environment 100, details of computer assets 102 (e.g. firewalls) providing security in the network environment 100, and the like. Likewise, for example, the security information can include security details of the computer assets 102, such as the configuration of the computer assets 102, system setting of the computer assets 102, software programs including security software programs installed on the computer assets 102, security settings of the computer assets 102, configuration policies of the computer assets 102, security policies of the computer assets 102, access information for the computer assets 102, and details of software programs installed on the computer assets.

In implementation, the security assessment tool 108 can be configured as a software program that is capable of being stored on and executed by a computer system, whether part of the network environment 100 or external to the network environment 100. The security assessment tool 108 can be written in a variety of programming languages, such as JAVA, C++, Python code, Visual Basic, hypertext markup language (HTML), extensible markup language (XML), and the like to accommodate a variety of operating systems, computing system architectures, etc. FIG. 1B illustrates a more detailed view of the security assessment tool 108. As illustrated, the security assessment tool 108 can be configured as a stand-alone software program and can include a scanner 110, a threat model 112, a score module 114, and one or more interfaces 116. While FIG. 1B illustrates the components as being part of the security assessment tool 108, the components can be separate software programs that communicate with the security assessment tool 108. Likewise, the security assessment tool 108, itself, can be a component of another software program.

The scanner 110 can include one or more software modules or tools that can scan the network environment 100 and the computer assets 102. The scanner 110 can be configured to determine the structure of the network environment 100 and identify the computer assets 102. Likewise, the scanner 110 can be configured to determine the security information for the network environment 100. Accordingly, the scanner 110 can be configured to include the necessary logic, commands, algorithms, and code to scan the network environment 100 and to communicate computer assets 102. For example, the scanner 110 can include various types of network scanners and vulnerability scanners, such as NeXpose™ or Metasploit™ from Rapid7, LLC.

The threat model 112 can be a listing of known security threats to network environments. The threat model 112 can include the identification of the known security threats and details of the security threats. The details can include the types of the computer assets 102 that are vulnerable to the known security threats, the affect of the known security threats, one or more counter measures that address the known security threats, and the like.

The score model 114 can include the necessary logic, commands, algorithms, and code utilized by the security assessment tool 108 to determine the overall security assessments and provide recommendations as described herein. The score model 114 can include a listing of the counter measures to security threats and a weighting value associated with each of the counter measures. The weighting value can represent the effectiveness of a particular counter measure.

The security assessment tool 108 can also include an interface 116. The interface 116 can be configured to allow one or more users to interact with the security assessment tool 108. The interface 116 can be configured to provide one or more graphical user interfaces (GUIs) and/or command-line interfaces to allow a user to interact with the security assessment tool 108. Likewise, the interface 116 can be configured to provide one or more application programming interfaces (APIs) to allow other software programs to interact with the security assessment tool 108. As described herein, the security assessment tool 108 will be described with reference to a user interacting with the security assessment tool 108. In implementations, a user can include a one or more persons and/or one or more software programs that can interact with the security assessment tool 108.

In implementations, a user can utilize the interface 116 interact with the security assessment tool 108 to perform the overall security assessment. The user can utilize the interface 116 to initiate a security assessment of the network environment 100. The user can utilize the interface 116 to enter information about the network environment 100 and the computer assets 102. For example, the user can enter information about the structure of the network environment 100 such as network addresses of the network environment 100. Likewise, for example, the user can enter information about the computer assets 102, such as identification of the computer assets 102, access information for the computer assets 102, and the like. The security assessment tool 108, for example, the scanner 110, can utilize the information provided by the user when identifying the computer assets 102 and when determining the security information for the network environment 100.

The security assessment tool 108 can utilize the interface 116 to output the results of the overall security assessment. The results can include the security score relative to the potential security threats and the overall security score determined by the security assessment tool 108. The results can also include one or more recommendations for improving the security score relative to the potential security threats and the overall security score. For example, the one or more recommendations can include deploying a new counter measure, changing a security setting of the computer assets 102, changing a system setting of the computer assets 102, changing a security policy of the computer systems 102, updating software of the computer assets 102, installing security software on the computer assets 102, and improving access information for the computer assets 102.

As illustrated, the security assessment tool 108 can be configured to access one or more security resources 118. The security resources 118 can be a source, whether internal or external to the network environment 100, that provides information about security threats and counter measures. For example, the security resources 118 can include security experts, security forums, security literature, empirical security testing platforms, and the like. Likewise, for example, the security resource 118 can include the user of the security assessment tool 108. The security assessment tool 108 can utilize the security resources 118 to generate and update the threat model 112. The security assessment tool 108 can also utilize the security resources 118 to generate and update the score model 114. For example, the security assessment tool 108 can utilize the security resources 118 to determine effectiveness metrics for the counter measures. The effectiveness metrics can be utilized to determine and update the weighting values for the counter measures.

FIG. 2 illustrates an example of a process 200 for assessing the security of the network environment 100, according to various implementations. The illustrated stages of the process 200 are examples and that any of the illustrated stages can be removed, additional stages can be added, and the order of the illustrated stages can be changed.

As illustrated, at 202, the process can begin. At 204, the security assessment tool 108 can determine the computer assets 102 in the network environment 100. The security assessment tool 108 can scan the network environment 100 to identify the computer assets 102 in the network environment 100. Likewise, the security assessment tool 108 can receive an identification of computer assets 102 from a user of the security assessment tool 108. Additionally, the security assessment tool 108 can receive, from a user, information about the network environment 100 and the computer assets 102 to assist in scanning the network environment 100.

In 206, the security assessment tool 108 can determine an actual deployment of counter measures on the computer assets. To determine the actual deployment of the counter measurers, the security assessment tool 108 can determine security information of the network environment 100. The security assessment tool 108 can scan the network environment 100 and the computer assets 102 to identify security information. Likewise, the security assessment tool 108 can receive the security information from a user of the security assessment tool 108. Additionally, the security assessment tool 108 can receive, from a user, information about the network environment 100 and the computer assets 102 to assist in scanning the network environment 100.

The security information can include any information about the structure of the network environment 100 and any information about the computer assets 102. For example, the security information can include security details of the network environment 100, such as security polices of the network environment 100, details of computer assets 102 (e.g. firewalls) providing security in the network environment 100, and the like. Likewise, for example, the security information can include security details of the computer assets 102, such as the configuration of the computer assets 102, system setting of the computer assets 102, software programs including security software programs installed on the computer assets 102, security settings of the computer assets 102, configuration policies of the computer assets 102, security policies of the computer assets 102, access information for the computer assets 102, and details of software programs installed on the computer assets.

Once the security information is determined, the security assessment tool 108 can determine potential security threats to the network and determine counter measures to address the potential security threats. Based on the security information, the security assessment tool 108 can examine the threat model 112 to identify the potential security threats to the network environment 100. Additionally, from the threat model 112, the security assessment tool 108 can identify counter measure that can address the potential security threats to the network environment 100.

For example, based on the type and configurations of computer assets 102, the security assessment tool 108 can determine potential security threats. For instance, if one or more of the computer assets 102 are running a particular OS or a particular software program, the security assessment tool 108 can determine any potential security threats and any counter measures that are applicable to the particular OS or software program. Likewise, for instance, if one or more of the computer assets 102 are connected to a public network (e.g. the internet), the security assessment tool 108 can determine any potential security threats and any counter measures that are associated with public networks.

Then, the security assessment tool 108 can determine an actual deployment of the counter measures in the network. Based on the security information and potential security threats, the security assessment tool 108 can determine which counter measures are actually deployed in the network environment 100 and on the computer assets 102. The security assessment tool 108 can determine which of counter measures are deployed and the coverage of the counter measures (e.g. on which computer assets 102 are the counter measures deployed).

In 208, the security assessment tool 108 can determine an overall security score for the network based on the actual deployment of the counter measures, potential security threats, and an effectiveness of the counter measures. The security assessment tool 108 can determine the overall security score based on potential security threats to the network environment 100, the actual deployment of the counter measures in the network environment 100, and effectiveness on the deployed counter measures. The overall security score can include security scores for different security threats. The security score for each security threat can reflect the actual deployment of counter measures for each counter measure and the effectiveness of the deployed counter measures. The overall security score can be the combination of the security scores for each potential security threat.

The security score for each potential security threat and the overall security score can be a numerical value that represents the overall security score for the network environment 100, where a higher numerical value represents better security relative to lower numerical values. For example, the security score for each potential security threat and overall security score can be a numerical value between “0” and “10,” where “0” represents no security for potential security threats and “10” represents complete coverage for the potential security threats. For instance, if for a particular security threat, the network environment 100 has deployed, on 100% of the computer assets 102, a counter measure that is 50% effective in mitigating a the particular security threat. In this instance, the security assessment tool 108 can determine that the overall security score is 5.

The above describes an example of the general process for determining the overall security score. A complete description of examples of determining the security score can be found in the related application, U.S. patent application Ser. No. ______ filed ______, entitled “SYSTEMS AND METHODS FOR DETERMINING AN OBJECTIVE SECURITY ASSESSMENT FOR A NETWORK OF ASSETS” by HD Moore, Roy Donald Hodgman, Dana Elizabeth Wolf, and Matthew Robert Hathaway, the disclosure of which is incorporated by reference herein in its entirety.

In 210, the security assessment tool 108 can determine recommendations for improving the overall security score. The recommendations can include any actions, procedures, processes, and the like for improving the security score relative to the potential security threats and the overall security score. For example, the one or more recommendations can include deploying a new counter measure, changing a security setting of the computer assets 102, changing a system setting of the computer assets 102, changing a security policy of the computer systems 102, updating software of the computer assets 102, installing security software on the computer assets 102, and improving access information for the computer assets 102.

In 212, the security assessment tool 108 can output the overall security score and the recommendations for the network environment 100. For example, the security assessment tool 108 can output the security score for each potential security threat and overall security score via the interface 116. The security assessment tool 108 can output the value of the security score for each potential security threat and overall security score in addition to recommendations to improve the overall security score.

In 214, the security assessment tool 108 can repeat the process above, over time, to determine new overall security scores. As new security threats arise, computer assets are added and removed from the network, new counter measures are determined, and as new counter measured are deployed, the security assessment tool 108 can determine new security score for each potential security threat and a new overall security score. Likewise, the security assessment tool 108 can determine impact of the changes on the new scores.

In 216, the security assessment tool 108 can perform trending analysis over time. The trending analysis can be any procedure or process that determines how the security assessment changes over time. For example, the security assessment tool 108 can track the change in the overall security (or security scores for potential threats), over time, and output a graph or other indication of the changes over time. Likewise, for example, the security assessment tool 108 can track the change in deployment of counter measures, over time, and output a graph or other indication of the changes over time.

In 218, the process can end, repeat, or return to any point.

FIG. 3 illustrates an example of a process 300 for determining an overall security score and implementing recommendations, according to various implementations. The illustrated stages of the process 300 are examples and that any of the illustrated stages can be removed, additional stages can be added, and the order of the illustrated stages can be changed.

As illustrated, at 302, the process can begin. In 304, the security assessment tool 108 can initially determine computer assets in a computer network and counter measures deployed on the computer assets. For example, when the security assessment tool 108 first examines the network environment 100, the security assessment tool 108 can determine the computer assets and security information for the network environment 100. The security assessment tool 108 can determine the computer assets and security information according to the procedures as discussed above in FIG. 2.

In 306, the security assessment tool 108 can determine the overall security score and the recommendations based on the initial determination. The overall security scores can represent the initial overall security scores before performing any of the recommendations. The security assessment tool 108 can determine the overall security score based on the actual deployment of the counter measures, the potential security threats to the network environment, and an effectiveness of the counter measures according to the procedures as discussed above in FIG. 2.

The recommendations can include any actions, procedures, processes, and the like for improving the security score relative to the potential security threats and the overall security score. For example, the one or more recommendations can include deploying a new counter measure, changing a security setting of the computer assets 102, changing a system setting of the computer assets 102, changing a security policy of the computer systems 102, updating software of the computer assets 102, installing security software on the computer assets 102, and improving access information for the computer assets 102.

In 308, one or more of the recommendations can be implemented in the network environment 100. The recommendations can be implemented by the security assessment tool 108. For example, the security assessment tool 108 can access the computer assets and perform the recommended action, such as deploying a new counter measure, changing a security setting of the computer assets 102, changing a system setting of the computer assets 102, changing a security policy of the computer systems 102, updating software of the computer assets 102, installing security software on the computer assets 102, and improving access information for the computer assets 102.

Likewise, a user or other computer system in the network environment 100 can implement the one or more recommendations. If performed by the user, the security assessment tool 108 can output an identification of the one or more recommendations and instructions for performing the one or more recommendations. For example, if the recommendation is changing a security setting of a particular computer asset 102, the security assessment tool 108 can output an identification of the particular computer asset 102, an identification of the security setting to be changed, and instructions for changing the security setting. Based on the output identification and instructions, the user can implement the one or more recommendations.

After the initial assessment, the security assessment tool 108 can perform the security assessment over time to determine have the overall security score changes relative to changes in the network environment 100. In 310, the security assessment tool 108 can determine a change in computer assets in a network, change in counter measures deployed, or change in potential security threats. The security assessment tool 108 can rescan the computer assets 102 and determine new security information and changes in the security information. Likewise, the security assessment tool 108 can determine if computer assets 102 have been removed and added. Additionally, the user of the security assessment tool 108 can enter new security information, changes in the security information, and changes in the computer assets 102. Additionally, the security assessment tool 108 can determine, by examining the threat model 112, new security threats, changes to existing security threats, new counter measures, and changes to existing counter measures.

In 312, the security assessment tool 108 can determine a new overall security score and the new recommendations for improving the security score. The overall security scores can represent the initial overall security scores before performing any of the recommendations. The security assessment tool 108 can determine the overall security score based on the actual deployment of the counter measures, the potential security threats to the network environment, and an effectiveness of the counter measures according to the procedures as discussed above in FIG. 2.

The recommendations can include any actions, procedures, processes, and the like for improving the security score relative to the potential security threats and the overall security score. For example, the one or more recommendations can include deploying a new counter measure, changing a security setting of the computer assets 102, changing a system setting of the computer assets 102, changing a security policy of the computer systems 102, updating software of the computer assets 102, installing security software on the computer assets 102, and improving access information for the computer assets 102.

In 314, one or more of the new recommendation can be implemented. The new recommendations can be implemented by the security assessment tool 108. For example, the security assessment tool 108 can access the computer assets and perform the recommended action, such as deploying a new counter measure, changing a security setting of the computer assets 102, changing a system setting of the computer assets 102, changing a security policy of the computer systems 102, updating software of the computer assets 102, installing security software on the computer assets 102, and improving access information for the computer assets 102.

Likewise, a user or other computer system in the network environment 100 can implement the one or more new recommendations. If performed by the user, the security assessment tool 108 can output an identification of the one or more recommendations and instructions for performing the one or more recommendations. For example, if the recommendation is adding a new counter measure, the security assessment tool 108 can output an identification of the counter measure, an identification of the computer assets affected by the new counter measure, and instructions for adding the new counter measure. Based on the output identification and instructions, the user can implement the one or more recommendations.

In 316, the security assessment tool 108 can repeat the process over time as conditions in the network environment 100 change. The security assessment tool 108 can automatically repeat the process at predefined times or at the predetermined internals. Likewise, the security assessment tool 108 can repeat the process at the request of a user or other computer system.

In 318, the security assessment tool 108 can perform trending analysis over time. The trending analysis can be any procedure or process that determines how the security assessment changes over time. For example, the security assessment tool 108 can track the change in the overall security (or security scores for potential threats), over time, and output a graph or other indication of the changes over time. Likewise, for example, the security assessment tool 108 can track the change in deployment of counter measures, over time, and output a graph or other indication of the changes over time.

In 320, the process can end, repeat, or return to any point.

FIGS. 4A-4V illustrate examples GUIs provided by the interface 116 that can be used to communicate with the security assessment tool 108. The examples of the GUI, as described below, can be provided locally at a computer system executing the security assessment tool 108, such as displayed on a display. Additionally, the examples of the GUI, as described below, can be provided remotely to computer system, for example, in the form of web pages. Likewise, the examples of the GUIs can be provided via one or more application programming interfaces (APIs) to allow other software programs to interact with the security assessment tool 108.

As illustrated in FIG. 4A, the security assessment tool 108 can provide a GUI 400. In this example, the GUI 400 can allow a user to enter information about themselves that allows the security assessment tool 108 to create an account with the security assessment tool 108. The GUI 400 can include a window 401 that allows a user to provide their name, a user name, a password, and an email address. The security assessment tool 108 can utilize the account to grant access to the user, store preferences of the user, and the like. Once the account is created, the user can utilize fields and widgets 402 to access the security assessment tool 108 using the username and password.

Once the user has created an account, the security assessment tool 108 can provide a GUI 405 as illustrated in FIG. 4B. The GUI 405 can allow the user to initiate a scan of the network environment 400, for example the initial scan of the network environment 400. The GUI 405 can include fields 406 that allow the user to enter information about the network environment 100, such as the domain credentials of the network environment 100 that allow the security assessment tool 108 to access the network environment 100. The GUI 405 can also include a widget 407 that causes the security assessment tool 108 to initiate the scan. During the scan, the security assessment tool 108 can determine the computer assets 102 in the network environment 100 and the security information of the computer assets 102.
