Threat Detection Rules (NET-003-R003) - NET-003

Requirement Details & Guidance

NET-003-R003 · NET-003

Why This Requirement Exists

Supports network threat detection, IDS/IPS, detection rules, alerting and validation by ensuring that threat detection rules is governed and implemented consistently, reducing unauthorized access, network attack exposure, service disruption, and security control gaps.

Implementation Guidance

Document the required control objective and scope; assign an accountable owner; define approved standards and configurations; implement the control across applicable network environments; integrate it with monitoring and change management; retain evidence; and review effectiveness periodically. For threat detection rules, detect relevant network threats using defined controls and telemetry.
