Abstract: Systems, methods, and apparatuses prevent malicious network traffic from accessing or being transmitted to trusted network resources in a network environment. In one embodiment, a management microservice initializes a security microservice on a computing device and configures a network interface as a secure channel for communications with the security microservice. When the management microservice authenticates the network interface, the management microservice enables a data channel interface for the security microservice, allowing the security microservice to receive network traffic from other security microservices. Prior to enabling the data channel interface, the security microservice does not have an active interface with any other security microservices, which prevents any traffic, including malicious network traffic from reaching areas of the security microservice during the initialization process.

Abstract: A set of attributes of a particular asset of a computing environment is identified that are determined from data collected by one or more utilities in the computing environment. A criticality rating is automatically determined for the particular asset based at least in part on the set of attributes. A security activity is caused to be performed relating to the particular asset based on the automatically determined criticality rating of the particular asset.

Abstract: System, methods, and apparatuses enable a network security system to more efficiently perform pattern matching against data items. For example, the disclosed approaches may be used to improve the way in which a deep packet inspection (DPI) microservice performs pattern matching against data items (e.g., network traffic, files, email messages, etc.) in order to detect various types of network security threats (e.g., network intrusion attempts, viruses, spam, and other potential network security issues). A DPI microservice generally refers to an executable component of a network security system that monitors and performs actions relative to input data items for purposes related to computer network security.

Abstract: A method in one example implementation includes extracting a plurality of data elements from a record of a data file, tokenizing the data elements into tokens, and storing the tokens in a first tuple of a registration list. The method further includes selecting one of the tokens as a token key for the first tuple, where the token is selected because it occurs less frequently in the registration list than each of the other tokens in the first tuple. In specific embodiments, at least one data element is an expression element having a character pattern matching a predefined expression pattern that represents at least two words and a separator between the words. In other embodiments, at least one data element is a word defined by a character pattern of one or more consecutive essential characters. Other specific embodiments include determining an end of the record by recognizing a predefined delimiter.

Abstract: Systems, methods, and apparatuses enable evaluating encrypted or obfuscated data packets being transmitted over a connection in a networked environment. In an embodiment, a security service utilizes one or more microservices operating as detectors to analyze characteristics of an encrypted or obfuscated network connection. Using the information from the detectors, the security service classifies the type of encryption protocol used on an encrypted connection and determines an extrapolated protocol state. Using the extrapolated protocol state with additional information received from the detectors, the security service determines a risk level associated with the connection and executes security actions on the connection based on the risk level.

Abstract: Systems, methods, and apparatuses enable deploying and executing a security policy on endpoints in a network. In an embodiment, a security orchestrator determines a set of endpoints in a network and determines transformed endpoints from the determined set of endpoints through an endpoint transformation process. The security orchestrator determines a connectivity vector for at least a first transformed endpoint and a second transformed endpoint, where the connectivity vector includes properties associated with the corresponding transformed endpoint. Using the properties from the connectivity vector of the first transformed endpoint, a security policy is generated and deployed to the first transformed endpoint. Based on a comparison of the connectivity vectors of the first and second transformed endpoints indicating a similarity between the first and second transformed endpoints, the security policy is further deployed to the second transformed endpoint.

Abstract: Systems, methods, and apparatuses enable updating security policies in response to detecting attack activity or security threats. In an embodiment, security microservices detect attack activity sent between resources within an internal network. In response, the security microservices correlate the attack activity to externally accessible resources that were the initial entry point for the attack activity to the internal network. Based on this correlation, the security microservices update security policies bi-directionally to prevent the spread of future attack activity in the internal network between resources at a same level in the internal network and between resources at different levels in the internal network.

Abstract: Systems, methods, and apparatuses enable a microservice-based application to dynamically update components of the system without disrupting messaging occurring between microservices in the system. Microservices of a microservice-based application store data indicating mappings between data object versions and message object versions and which is used update system components in a controlled manner. As used herein, a data object generally refers to any data generated by a microservice and that can be sent to one or more other microservices using a publish-subscribe messaging pattern or other messaging architecture. A message object refers to data used to encapsulate one or more data objects and used to send the data object from one component to another in the system.
