- Conduct detection gap analysis, tune alerting mechanisms, and eliminate false positives at the MSS customer environment
- Perform regular fine-tuning and optimization of detection rules, correlation logic, and alert thresholds across SIEM, EDR, and other security platforms to enhance detection accuracy and reduce false positives.
- Continuously assess detection efficacy based on incident feedback and threat landscape evolution, implementing improvements accordingly.
- Collaborate with red/purple teams to validate detection logic and build threat-informed defenses.
- Regularly review, update, and enhance detection logic to ensure alignment with the latest threat intelligence, adversary TTPs, and evolving attack techniques.
- Maintain relevancy and effectiveness of security detections by incorporating insights from threat hunts, incident response cases, red team exercises, and industry best practices.
