Mapped to NIST 800-171 Requirement: 3.14.2
CMMC Assessment Objective: SI.L2-3.14.2[c]
What This Control Means
This is the operational validation checkpoint.
You must demonstrate that:
• Your monitoring tools (SIEMs, EDR, IDS/IPS, etc.) are actively detecting unauthorized or suspicious behavior
• Unauthorized access attempts, policy violations, or privilege escalations are caught, logged, and escalated
• Detection covers all systems involved in CUI handling—not just perimeter devices
Monitoring must be alive and functioning, not just planned or documented.
Why It Matters
Without active detection:
• Intrusions and insider threats can escalate without being noticed
• CUI can be accessed or exfiltrated without triggering an alarm
• Incident response efforts will be too little, too late
• Compliance failures will occur for NIST 800-171 and CMMC requirements
Real-time monitoring is critical for rapid detection and response.
How to Implement It
1. Confirm Monitoring Systems Are Operational
• Ensure SIEM, EDR, IDS/IPS solutions are collecting logs, correlating events, and sending alerts
• Validate that suspicious activities generate real-time notifications
2. Validate Detection Use Cases
• Review alerts and event correlation rules for:
◦ Failed login attempts
◦ Access outside business hours
◦ Unauthorized privilege escalation attempts
◦ Data exfiltration indicators
3. Test Detection Mechanisms
• Perform internal tests simulating unauthorized activities:
◦ Invalid login attempts
◦ Attempting to access restricted folders
◦ Simulated insider threat behavior
4. Document Detection Activities
• Save alerts, event logs, and incident reports tied to monitoring mechanisms
Evidence the Assessor Will Look For
• Logs showing detection of unauthorized or suspicious events
• SIEM or monitoring tool dashboards showing active alerts
• Incident records triggered by unauthorized system use detections
• Screenshots showing configured rules or correlation policies
• Documentation of test activities validating monitoring functionality
Common Gaps
• Monitoring systems deployed but alerting disabled or misconfigured
• Only network perimeter monitoring—not endpoint or user behavior monitoring
• No alerts configured for privilege escalation or unauthorized data access
• No logs or evidence of unauthorized use detections
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Tracking live unauthorized use detection across your CUI systems
• Logging and linking detection events to user accounts, devices, and system activities
• Alerting on unauthorized login attempts, policy violations, or suspicious access patterns
• Generating audit-ready documentation proving active system monitoring and threat detection
• Providing dashboards to visualize unauthorized use trends across your environment
With Cuick Trac, unauthorized access attempts aren’t invisible—they’re detected, logged, and addressed fast.
Final CTA
Detection only matters if it’s real, live, and working.
Schedule a Cuick Trac demo to validate your system monitoring and protect your CUI environment against unauthorized use.
