Remediation validation
Confirming, typically by rescan, that a fix removed exposure to a vulnerability.
Why it matters
Many scanners mark a finding resolved when it stops appearing, which is not proof of a fix.
How it works
- Fix is applied.
- Rescan runs.
- Result is compared with the original finding.
- Closure is recorded with the rescan result.
