Episode 55 — Analyze Monitoring Data Like a Defender: SIEM Parsing, Retention, Baselines, Correlation
This episode teaches how to analyze monitoring data the way defenders do when they are trying to separate real threats from background noise, which SecurityX tests because detection success depends on data quality and interpretation, not just tooling. You’ll learn why SIEM parsing and normalization matter, including how field extraction, time handling, and consistent identity attributes determine whether correlation works or silently fails. Retention is covered as both a compliance decision and an investigative capability, including how long you need data to answer common questions, how storage tiers affect searchability, and how gaps in retention can turn an incident into guesswork. We’ll build baselines for “normal” behavior, showing how to use historical patterns to spot deviations in authentication, network access, data movement, and administrative actions without relying on fragile assumptions. Correlation is treated as a design discipline, including how to link endpoint, identity, cloud, and application signals into a narrative that supports triage and containment. Troubleshooting includes missing logs, broken parsers after platform updates, noisy sources that drown out high-value alerts, and the practical steps to validate that what you believe is being collected is actually arriving and usable.
