Vulnerability Validation

Confirming that a reported vulnerability truly exists and that remediation actually fixed it.

Definition

Validation includes reviewing evidence, checking versions manually, correlating with other scanners or logs, and rescanning after remediation. It eliminates false positives and confirms closure of findings before reporting them as resolved.

Example

Rescanning servers after patching to confirm the finding no longer appears.

Exam tip

Rescan to verify remediation is the expected final step of the lifecycle.
