The company formally deploys behavioural analysis to identify anomalous activity that rules-based detection misses
Sekit's UEBA/behavior analytics policy is part of A.5.1's topic-specific policy layer: it records the deliberate decision on whether anomaly detection is in scope, what it watches and who acts on it.
Deciding deliberately what behavioral analysis should watch and who acts on it is the scoping decision that makes A.8.16's anomaly monitoring workable rather than noise.
