Behavioral Baselining
"User behavior—including access, movement, and intent—is baselined, logged, and analyzed using UEBA and cross-domain signals."
This capability evaluates whether the organization has the ownership, process, evidence, and oversight needed to manage behavioral baselining as part of a defensible insider risk monitoring program.
What This Capability Means
Behavioral Baselining assesses whether user behavior, access, movement, and contextual indicators are baselined, logged, and analyzed using user, peer group, role, and cross-domain signals.
Why This Capability Matters
Insider risk rarely depends on a single event. Behavioral baselining helps teams distinguish routine activity from deviations that may indicate elevated exposure or require contextual review.
AI Monitoring Context
Behavioral baselining often relies on AI or machine-learning techniques. Programs should document baseline assumptions, peer-group logic, drift review, false-positive handling, and safeguards against unfair or disproportionate impact.
Weakness vs. Maturity Indicators
Behavioral baselines are not established by user, peer group, or role.
Alerts are treated as isolated events instead of patterns over time.
HR, legal, privacy, and business context are not governed or consistently applied.
High-risk users are not monitored proportionately or consistently.
Model outputs are not reviewed for explainability or fairness.
Historical baselines are established by user, peer group, role, and relevant business context.
Deviation from baseline is evaluated with privilege, timing, asset sensitivity, and intent indicators.
Use of contextual data is governed by legal, HR, and privacy review.
Enhanced monitoring tiers are documented and proportionate.
Behavioral analytics are connected to triage, investigation outcomes, and tuning.
Questions Leaders Should Ask
Security, legal, and operational executives can use these core questions to evaluate ownership, effectiveness, and evidence.
Are behavioral baselines established for users, roles, and peer groups?
How are deviations prioritized?
What contextual data is permitted, and who approves its use?
Are high-risk users subject to proportionate enhanced monitoring?
How are behavioral analytics validated and improved?
