What it means
Incident closure criteria define the evidence and approvals required before an event leaves active response and enters monitoring, remediation, or normal operations.
Why it matters
Clear criteria prevent administrative closure while unresolved access, impact, evidence, or corrective actions remain.
Practical focus
- Define criteria for containment, eradication, recovery, evidence, and ownership
- Document residual risk and open actions
- Require appropriate technical and business approval
- Set follow-up dates for deferred remediation
Common mistakes
- Closing because alerts stopped
- Requiring every long-term improvement before operational closure
- Losing ownership of deferred actions
- Failing to record residual uncertainty
