Intrusion Detection Systems: What They Catch and Where They Fail

A SIEM log curation checklist: nine log source categories ranked by investigation value into tiers, guiding parser work, retention spending, and detection engineering.

Bishop Fox explains Purple Teaming—merging Red Team offense with Blue Team defense—to validate security investments, establish measurable baselines and communicate evidence-based ROI.

This coverage gives security teams current context for monitoring, validation, and remediation.

GitLab's Signals Engineering team built WATCH, a breach and attack simulation framework that runs real malicious behavior to verify detections fire end-to-end from log source through SIEM and SOAR.

Borrowing Wald's survivorship-bias lesson and the 'dark figure of crime', the author argues string rules only catch known artifacts, so behavioral detection is the only route to the unknown.

Falcon Platform IOAs bring CrowdStrike-managed, adversary-driven detections to Falcon Next-Gen SIEM, correlating telemetry across modules and third-party sources, auto-deployed as new threats emerge.
