After remediation of a vulnerability, what is the recommended next step in a TA program?

• A. Ignore the remediation and move on.
• B. Document the remediation without any verification.
• C. Re-attest to confirm effectiveness.
• D. Request external certification.

Answer: (C)

Verification that remediation actually solves the issue is essential after fixing a vulnerability. Re-attestation provides documented confirmation that the mitigation works and that the risk is reduced as intended, helping ensure the environment remains aligned with security baselines and standards. This step also helps catch any unintended side effects from the fix. Ignoring the remediation leaves risk unaddressed, and simply documenting the fix without verification does not prove it was effective. External certification is broader and may be unnecessary as the immediate next action in a typical TA workflow.
