Worked on enhancing Linux SysRq abuse detection within the splunk/security_content repository by developing a new detection rule, refining macro references for accurate filtering, and renaming detection files to align with updated logic. Addressed data quality in the splunk/attack_data repository by removing outdated log entries and correcting YAML dataset source fields, improving the reliability of threat detection. Applied skills in Detection Engineering, Data Management, and Linux Security, leveraging Splunk and YAML to streamline monitoring and reduce false positives. Demonstrated careful attention to rule development, macro usage, and dataset configuration, contributing to more efficient triage and higher-quality security content.
