Why this module exists. Detection engineering — the systematic creation, tuning, and maintenance of SIEM/EDR detection rules — is what separates a noisy SOC from an effective one. This module covers Sigma rules, the MITRE ATT&CK mapping, the test-tune-deploy lifecycle, and the metrics that measure detection programme health.
What detection engineering is
- Design rules that fire on adversary behaviour, not noise.
- Test rules against historical data and red-team data.
- Tune to acceptable signal-to-noise.
- Deploy with documentation.
- Maintain — update when adversary techniques evolve.
