Insider Risk
Insider Risk Programs Without Surveillance Theater
Proportionate monitoring and HR collaboration.
Marcus Chen · Staff Security Architect · 11 min read · 2025-03-06
Executive summary
Proportionate monitoring and HR collaboration. Security leaders evaluating platforms in Insider Risk should treat visibility, response automation, and measurable risk reduction as co-equal goals—not sequential phases.
Problem context
Teams often bolt tools together without a coherent operating model. Alert volume rises, context stays fragmented, and mean time to contain stagnates. Cybrion's approach treats people as first-class telemetry in a tenant-isolated AI Security Operating System.
Architecture patterns
- Normalize events early.
- Enrich with identity and asset criticality.
- Map detections to MITRE ATT&CK.
- Automate only after human-approved playbooks stabilize.
# Example detection sketch
title: Suspicious privilege escalation
detection:
selection:
event_type: auth.privilege_change
severity: high
condition: selectionImplementation checklist
- Inventory authoritative identity and asset sources
- Define severity and ownership rules
- Establish retention tiers aligned to investigation needs
- Wire SOAR actions with approval gates
- Measure false positive rate weekly for 90 days
Detection ideas
Focus on behaviors: anomalous token use, unusual outbound volume, and privileged role changes outside change windows. Prefer high-confidence correlations over single noisy indicators.
Common pitfalls
Collecting every log without a question to answer, enabling automation before containment safety checks, and reporting vanity metrics to the board.
Next steps
Start a Cybrion trial, import a week of high-value telemetry, and run one purple-team exercise against a mapped ATT&CK technique. Use the results to prioritize detections—not tools.
