Certified: The Security+ Prepcast

Patching and encryption are two of the most basic yet essential components of any security strategy—one protects against known vulnerabilities, the other safeguards data from unauthorized access. In this episode, we cover why timely and systematic patching is critical, explaining how attackers often exploit known vulnerabilities with publicly available tools within hours—or even minutes—of disclosure. We highlight the risks of unpatched systems in both operating systems and applications, and discuss how automated patch management platforms can help maintain coverage. On the encryption side, we examine the importance of encrypting both data at rest and in transit using protocols like TLS and AES, as well as ensuring proper key management practices. Encryption alone won’t prevent compromise, but it limits the damage by rendering stolen data useless. Together, patching and encryption serve as front-line and fallback defenses in a layered security model.
