Episode 23 — Prevent and Detect Malware Before It Wrecks You
This episode focuses on malware controls from a QSA validation perspective, because the exam expects you to understand both prevention and detection, and to recognize that coverage and operational effectiveness matter more than brand names. You’ll learn how to define the systems that require malware protection based on exposure and function, including endpoints, servers, jump hosts, and administrative workstations that can touch the CDE. We explain what “actively running” and “kept up to date” should look like in evidence, and how to validate that signatures, engines, or detection content are current and not routinely failing. Practical examples show how exceptions are handled, how alerting and response workflows prove the control is real, and how to assess environments that use EDR, application allowlisting, or platform-native protections instead of traditional antivirus. Troubleshooting guidance addresses common issues like excluded directories, unmanaged assets, broken agents, noisy alerts that get ignored, and missing proof of remediation. By the end, you’ll be able to reason through malware scenarios and identify what a QSA must verify to reach a defensible conclusion.
