Certified: The Security+ Prepcast

Fixing a vulnerability doesn’t mean it’s gone—it means it needs to be verified. In this episode, we focus on the importance of validating remediation efforts to ensure that patches, configuration changes, and mitigation controls have actually addressed the issue without introducing new problems. This process includes rescanning affected systems, conducting follow-up audits, performing penetration tests if necessary, and reviewing logs for signs of continued exploitation. Validation helps teams avoid “check-box” fixes that look good on paper but leave systems just as vulnerable as before. We also discuss how to document remediation success for compliance reporting and long-term tracking. True remediation isn't complete until it's confirmed, tested, and measured—because assumptions are the enemy of security.
