ANOMALY DETECTION BASED ON COMMUNICATION BETWEEN ENTITIES OVER A NETWORK
First Claim
1. A method comprising:
- receiving, by a computer system, event data associated with a communication between an internal entity within a computer network and an external entity outside the computer network, the event data including an identifier associated with a particular entity, wherein the particular entity is the internal entity or the external entity;
analyzing, by the computer system, a plurality of characters in the identifier by processing the event data;
assigning, by the computer system, a feature score based on the analysis, wherein the feature score is indicative of a level of confidence that the identifier is machine generated; and
detecting, by the computer system, an anomaly based on the feature score.

Abstract
A security platform employs a variety techniques and mechanisms to detect security related anomalies and threats in a computer network environment. The security platform is “big data” driven and employs machine learning to perform security analytics. The security platform performs user/entity behavioral analytics (UEBA) to detect the security related anomalies and threats, regardless of whether such anomalies/threats were previously known. The security platform can include both real-time and batch paths/modes for detecting anomalies and threats. By visually presenting analytical results scored with risk ratings and supporting evidence, the security platform enables network security administrators to respond to a detected anomaly or threat, and to take action promptly.

29. A system comprising:
-
a processor; and a memory unit having instructions stored thereon, which when executed by the processor cause the system to; receive event data associated with a communication between an internal entity within a computer network and an external entity outside the computer network, the event data including an identifier associated with a particular entity, wherein the particular entity is the internal entity or the external entity; analyze a plurality of characters in the identifier by processing the event data; assign a feature score based on the analysis, wherein the feature score is indicative of a level of confidence that the identifier is machine generated; and detect an anomaly based on the feature score.

30. A non-transient computer readable medium containing instructions, execution of which by a computer system cause the computer system to:
-
receive event data associated with a communication between an internal entity within a computer network and an external entity outside the computer network, the event data including an identifier associated with a particular entity, wherein the particular entity is the internal entity or the external entity; analyze a plurality of characters in the identifier by processing the event data; assign a feature score based on the analysis, wherein the feature score is indicative of a level of confidence that the identifier is machine generated; and detect an anomaly based on the feature score.
