Episode 43 — Implement File Integrity Monitoring That Catches the Drift.
This episode explains file integrity monitoring as a practical detection and accountability control, not just a compliance artifact, and it shows why the exam expects you to understand scope selection and operational evidence. You’ll learn what types of files and directories typically matter most in a PCI context, including system binaries, configuration files, security settings, payment application components, and any scripts that influence transaction handling or access controls. We define core FIM concepts such as baselining, authorized change windows, alerting thresholds, and the difference between “changes detected” and “changes investigated,” then connect those definitions to what a QSA must verify during assessment. Realistic examples include web server configuration drift, unauthorized scheduled tasks, modified library files, and admin actions that alter authentication behavior, with a focus on how FIM integrates with change control and incident response. Troubleshooting considerations cover noisy alerts, missing coverage, agents disabled on critical hosts, baselines created after compromise, and evidence that alerts are generated but not acted on. By the end, you’ll know how to evaluate whether FIM is truly catching drift and producing defensible evidence, which is exactly what exam questions are designed to test.
