Phishing-Resistant MFA Rollouts (Part 4)

Executive summary

Extended guidance continuing passkeys, fido2, and fallback paths that don't weaken security. Security leaders evaluating platforms in Phishing 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 mfa as first-class telemetry in a tenant-isolated AI Security Operating System.

Architecture patterns

1. Normalize events early.
2. Enrich with identity and asset criticality.
3. Map detections to MITRE ATT&CK.
4. Automate only after human-approved playbooks stabilize.

# Example detection sketch
title: Suspicious privilege escalation
detection:
  selection:
    event_type: auth.privilege_change
    severity: high
  condition: selection

Implementation 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.
