# Recover Security Incident
## Overview
Return systems and people to a trusted operating state using explicit eradication and validation criteria. Recovery is complete only when restored behavior, security controls, access, monitoring, and residual risk are verified.
Read [references/recovery-gates.md](references/recovery-gates.md) for staged return-to-service gates.
## Workflow
1. Establish eradication criteria.
- Identify root/access path, persistence, affected identities/secrets, vulnerable configuration/code, related artifacts, and known scope.
2. Choose restore basis.
- Decide clean rebuild, known-good backup, patched image, repaired configuration, provider recovery, or controlled cleanup from evidence and integrity confidence.
3. Eradicate.
- Remove verified mechanisms, patch or mitigate the entry path, rotate/revoke secrets and sessions from trusted systems, repair policies/configuration, and preserve evidence of changes.
4. Restore in stages.
- Validate offline or isolated, restore dependencies/data, enable limited traffic/users, monitor, then broaden service.
5. Verify security and function.
- Reproduce the original detection/path as a negative test, confirm expected functionality, review access/persistence/network/logging, and check backups and monitoring.
6. Remove temporary controls deliberately.
- Inventory emergency rules, disabled services, isolation, temporary accounts, logging, tokens, and exceptions; retain only approved controls with owners/expiry.
7. Close and improve.
- Record timeline, root cause, affected scope, actions, notifications, evidence retention, lessons, structural hardening, and residual risk owner.
## Output
Return eradication evidence, restore basis, staged recovery results, negative retest, temporary-control disposition, monitoring window, lessons/actions, and residual-risk decision.
