Episode 67 — Centralize Logging Strategically: What to Collect, Why, and How Long

This episode teaches how to centralize logging with purpose so security teams can investigate, detect, and prove control effectiveness, aligning with exam objectives around monitoring strategy and operational resilience. You will learn how to choose log sources based on threat scenarios and business priorities, including identity events, endpoint activity, network flows, application logs, and key infrastructure changes, then decide retention based on investigative timelines and compliance expectations. We discuss normalization and time synchronization as prerequisites for useful correlation, protecting logs from tampering through access controls and immutability, and managing cost by tiering storage and prioritizing high-value sources first. A scenario explores an incident where key evidence is missing because a log source was never enabled, showing how source mapping and health checks prevent repeat failures. Troubleshooting considerations include noisy logs that hide meaningful signals, inconsistent parsing, and retention set by habit rather than need, emphasizing deliberate design and continuous review.
