UEBA explained: how behavioural analytics surface insider risk
UEBA stands for user and entity behaviour analytics. It is an approach that learns what normal activity looks like for people and systems, then highlights deviations that may indicate risk. Rather than relying only on fixed rules, it weighs many signals into a picture of relative risk.
The problem it solves
Security and integrity teams cannot investigate everything. The hard question is not usually whether anything is happening but where to look first. UEBA helps answer that by ranking users and cases according to behavioural risk, for example after-hours access, unusual data movement, or deviation from a peer group.
Why explainability is essential
A risk score is only useful in an investigation if it can be explained. A number produced by an opaque model cannot be justified to a reviewer, defended in a disciplinary process, or relied on in a report.
Good UEBA for investigations shows its working: which factors contributed, how they were weighted, and why the score is what it is. That transparency turns a signal into evidence a team can stand behind.

Chain of custody is the documented, unbroken record of who handled evidence and when. For digital evidence, getting it right is what makes findings hold up.
