Refined detection rules and updated their parameters based on telemetry data to improve threat coverage, reduce false positives, and accelerate incident response. Highlights include the feature: Enhanced Security Threat Detection Rules and Telemetry-based Parameter Tuning, implemented with collaboration across the team. Commit a9aaf494f630ca20385a4ddca0d26d22b86a2c56 (Improved detections based on telemetry data) with contributions from P4T12ICK, Bhavin Patel, and Nasreddine Bencherchali.

Concise monthly summary for 2026-03 highlighting endpoint detection enhancements in splunk/security_content. Delivered improvements focused on rule accuracy, discovery, and process relationship mapping across endpoint detections; added refined rules for VMware Tools path, rundll32-based bypass attempts, and updated process matching via YAML configuration. Expanded user discovery for whoami.exe and included pwsh.exe as a parent for logoff actions; overall detection rule coverage was increased to strengthen SOC visibility. Implemented through five YAML-based detection updates with 5 commits from the feature set. No standalone major bug fixes were reported this month; bug fixes are embedded within these rule improvements. Impact: higher detection accuracy, faster incident response, and reduced analyst toil through better rule coverage and clearer process relationships. Technologies/skills demonstrated include YAML-driven rule authoring, Windows security artifact analysis, process tree relationships, and cross-team collaboration (Co-authored-by).
