Connect the roles in Containment Eradication and RecoveryKeep confirmed scope, containment boundary, eradication work, and trusted recovery as separate roles.
Connect the roles in Containment Eradication and RecoveryA topic-specific model connects four distinct roles used to reason about containment eradication and recovery.
Incident evidenceEvidence maps assets identities paths and impact
Safety boundaryDecision limits spread and preserves operations
Removal processProcess removes persistence and stolen access
Recovery testBackup restores through clean dependencies
Verify Recurrence MonitoringConnect recurrence monitoring with its topic-specific inspection, expected outcome, and safety boundary.
