After a scan, you discover many false positives. What should you do first?

A.  Disable the scanner

B.  Update the scanner's database

C.  Perform a penetration test

D.  Reconfigure the network firewall

Correct Answer: B

Explanation:

Disable the scanner: This would not solve the issue of false positives and would leave your network unprotected from actual vulnerabilities.

Update the scanner's database: Updating the database with the latest signatures and rules is often the first step in resolving false positives. This will ensure that the scanner is using the most current information to evaluate your network's security.

Perform a penetration test: While a penetration test can provide a more in-depth analysis of your network's security, it's generally more time-consuming and costly than simply updating your scanner's database. Also, if the scanner is producing many false positives, a penetration test may also be affected or may require additional work to separate real vulnerabilities from false positives.

Reconfigure the network firewall: While tuning your network firewall is important, it's unlikely to resolve issues of false positives from a security scan. Also, doing so without accurately knowing your vulnerabilities (due to false positives) could introduce new security risks.
