Episode 17 — Lock down secure configurations across servers and endpoints
Secure configuration management converts general security principles into concrete, testable baselines for systems that can touch or influence cardholder data. This episode explains how the exam frames baselines as living standards: hardened images or templates, applied consistently, with deviations documented and approved. Expect to distinguish policy statements from technical artifacts like CIS-aligned checklists, configuration exports, and automated scan results. We emphasize the lifecycle: establishing a baseline, deploying it through controlled builds, validating with both automated and manual checks, and maintaining drift detection so unapproved changes are visible. You will see why least functionality, removal of default accounts, strict service enablement, and system time synchronization show up frequently in stems as evidence-backed configuration choices.
We expand with scenarios that force you to weigh completeness against operational friction. A server team may disable unused services yet forget to lock kernel parameters needed for network hardening, leaving a gap attackers can exploit. Endpoint administrators might set registry keys for script restrictions but fail to remove local admin rights, undermining the intended defense. The exam rewards answers that call for reproducible builds, version-controlled configuration scripts, documented exceptions with expiration dates, and periodic re-baselining after major software changes. Troubleshooting advice covers consolidating conflicting hardening guides, validating that configuration management tools cover remote offices and kiosks, and ensuring that scans report on both presence and correct values of settings. Correct selections pair prescriptive baselines with monitoring and approvals, producing evidence that systems start secure and stay secure under routine operations and change.
