What This Control Means
You must actively monitor your systems for:
• Intrusion attempts
• Malware infections
• Abnormal behaviors
• Indicators of compromise (IoCs)
Monitoring must be deliberate, ongoing, and cover all CUI-related systems. Effective cybersecurity monitoring is essential for protecting CUI systems from potential threats.
Why It Matters
Without monitoring:
• Attacks can occur and succeed unnoticed
• Early warning signs of breaches may be missed
• Malware infections can escalate from one system to your entire environment
• You will fail critical audit requirements for CMMC, DFARS, and NIST 800-171
Monitoring is your early detection and defense layer. Cybersecurity threat monitoring is crucial to maintaining compliance with cybersecurity standards and frameworks.
How to Implement It
1. Identify Monitoring Mechanisms in Use Examples:
• Intrusion Detection/Prevention Systems (IDS/IPS)
• Endpoint Detection and Response (EDR) tools
• SIEM (Security Information and Event Management) systems
• Cloud-native monitoring (e.g., AWS GuardDuty, Azure Defender)
• Antivirus and antimalware solutions with alerting
2. Define Monitoring Scope
• Cover:
◦ Servers, workstations, and mobile devices handling CUI
◦ Network boundary points
◦ Cloud platforms and storage locations
3. Document What’s Monitored
• Logins and access attempts
• File changes and sensitive data movements
• Unusual system behaviors or alerts from antivirus tools
• Unauthorized network traffic
4. Assign Responsibility
• Identify personnel or vendors responsible for monitoring, reviewing alerts, and escalating issues
Implementing these mechanisms aligns with NIST IT security guidelines and ensures comprehensive protection of CUI systems.
