You also take part in incident response: the gaps you find come from real incidents, and the fixes you build get tested by them.

• Find.



Map current telemetry and detections against MITRE ATT&CK; (Navigator/DeTT&CT;), including the cloud matrices (IaaS, SaaS, Identity Provider) for AWS, GCP and Azure; run adversary emulation and breach-and-attack-simulation tests; mine incidents, hunts, pentests and threat intel for techniques we couldn't see or stop; audit log-source health and asset coverage.
• Define. Turn each gap into a written item: technique, affected assets, risk, required telemetry, detection logic, mitigation, owner and acceptance test. Prioritise into a single backlog against the threats most relevant to aviation.
• Fix. Onboard and normalise log sources; build detections as code (Sigma as the source of truth, converted to KQL, SPL or Elastic/OpenSearch queries; version-controlled and tested in CI); tune to an agreed false-positive budget; work with platform owners to implement and verify preventive controls (hardening, EDR policy, identity and conditional acce
