III.B     Threat Monitoring

Threat monitoring policies should provide for continual and ad hoc monitoring of threat intelligence communications and systems, effective incident detection and response, and the use of monitoring reports in subsequent legal procedures. Management should establish the responsibility and authority of security personnel and system administrators for monitoring. Additionally, management should review and approve the tools used and the conditions for use.

Threat monitoring should address indicators of vulnerabilities, attacks, compromised systems, and suspicious users, such as those who do not comply with or seek to evade security policies. Monitoring should address incoming and outgoing network traffic, seeking to identify malicious activity and data exfiltration. Additionally, the monitoring process should be established and documented to independently monitor administrators and other users with higher privileges.
