Anomalies and events are detected and their potential impact understood. (NIST CSF 2.0: DETECT — DE.AE)
A compliant Anomaly & Event Detection Policy for NIST CSF 2.0 must include the following7 sections. Each section addresses a specific control requirement that auditors will review.
Policy objectives and detection program overview.
Normal network and system behavior documentation.
Required log sources: systems, network, applications, cloud.
SIEM rule management and tuning process.
Investigation and false-positive management.
Potential impact determination procedures.
Minimum retention periods and storage requirements.
This template shows the required structure. PoliWriter generates a fully customized Anomaly & Event Detection Policy that references your actual cloud providers, identity systems, tools, and team practices — ready for auditor review.
