To validate vulnerabilities effectively, which approach is recommended?

• A. Investigate each vulnerability further by manually testing.
• B. Rerun the scanner until it passes.
• C. Patch immediately without verification.
• D. Ignore results.

Answer: (A)

Validating vulnerabilities requires moving from automated detection to hands-on confirmation. After a scanner flags issues, manually testing each potential vulnerability lets you reproduce the condition in a controlled environment, determine if it’s actually exploitable, and measure the real impact. This produces concrete evidence (steps, conditions, potential access) that you can use to prioritize remediation and communicate risk. Automated tools can produce false positives or miss context that affects exploitability, so relying solely on them can lead to wasted effort or missed risks. Rerunning the scanner until it passes isn’t sufficient because it doesn’t verify exploitability or real impact; it may still miss issues in your environment or fail to distinguish false positives from true risks. Patching without verification risks applying unnecessary changes or failing to address the actual vulnerability if the remediation isn’t properly targeted. Ignoring results leaves critical security gaps.
