User and entity behavior analytics (UEBA) is a cybersecurity technique that uses machine algorithms to detect anomalous activities of users, hosts, and other entities in a network. It has become an integral part of security information and events management (SIEM) solutions today. Traditionally, security analysts had to write rules, so that their SIEM could detect threats whenever these rules were breached. With UEBA, no rules need to be written; threats are detected after analyzing the past behavior of users and entities. Both rules-based detection and UEBA are necessary to deal with today's sophisticated threats.
To detect anomalies, UEBA first learns about the expected behavior of all users and entities in a network and creates a baseline of regular activities for each of them. Any activity that deviates from this baseline gets flagged as an anomaly. The security analyst can then investigate the issue and take the necessary steps to mitigate the risk. UEBA solutions grow more effective the more experience they gain.Get whitepaper: Understanding UEBA
A risk score is calculated for each user and entity in the organization after comparing their actions to their baseline of regular activities. The risk score can range from anywhere between 0 to 100, indicating no risk to maximum risk, respectively. The risk score is dependent on factors such as the allotted weight of the action, the extent of the deviation from the baseline, the frequency of deviation, and the time elapsed since the deviation.
Here are some activities that might increase the risk score of users and entities, indicating possible insider threats, account compromise, and data exfiltration.
Log360 UEBA analyzes logs from different sources including firewalls, routers, workstations, databases, and file servers. Any deviation from normal behavior is classified as a time, count, or pattern anomaly.

UEBA maintains a risk score for each and every user and entity profile. Whenever an activity log for a user/entity differs from its baseline, the risk score of that particular profile increases. An increased risk score of a profile helps the IT admin to look into the matter immediately to prevent any security breach.
