What it means
Vulnerability remediation validation confirms that the weakness is actually removed or reduced, the correct asset was changed, and the fix did not create unacceptable side effects.
Why it matters
A closed ticket or successful deployment does not prove that the vulnerable condition is gone.
Practical focus
- Retest using an appropriate method
- Confirm asset identity and scope
- Record evidence and residual risk
- Monitor for regression or reintroduction
Common mistakes
- Closing from change status alone
- Retesting with the same flawed detection assumptions
- Ignoring compensating-control limitations
- Failing to validate related assets
