Mapped to NIST 800-171 Requirement: 3.14.2
CMMC Assessment Objective: SI.L2-3.14.2[d]
What This Control Means
This is the enforcement checkpoint.
You must show that:
• Unauthorized use detection (via SIEM, EDR, IDS/IPS, etc.) is always running
• Monitoring cannot be disabled or bypassed without administrative control and logging
• Any failures or attempts to circumvent monitoring are alerted and investigated
Detection must be a built-in, non-optional layer of your defense.
Why It Matters
Without enforcement:
• Threat actors could disable security tools and cover their tracks
• Insider threats could tamper with monitoring to evade detection
• Compliance violations would occur if critical systems operate without monitoring
• Your incident detection and response times would suffer drastically
Security monitoring must be continuous, mandatory, and tamper-resistant.
How to Implement It
1. Protect Monitoring Configurations
• Use RBAC (Role-Based Access Control) to:
◦ Limit who can modify or disable monitoring agents
◦ Restrict access to SIEM or logging system configurations
2. Monitor the Monitoring
• Set up heartbeat monitors and alerting for:
◦ SIEM agent disconnections
◦ EDR agent failures
◦ Logging interruptions from critical systems
3. Enforce Monitoring Requirements at System Enrollment
• New systems should not go live without verified monitoring agent installation
• Remote and cloud systems must be monitored from day one
4. Log and Investigate Monitoring Failures
• Investigate and document:
◦ Service interruptions
◦ Agent tampering
◦ Monitoring failures detected by oversight systems
Evidence the Assessor Will Look For
• Policy requiring enforcement of monitoring across CUI systems
• Logs showing alerts triggered by monitoring service failures
• Screenshots proving protection against monitoring tampering
• Change management records for monitoring system updates
• Incident reports tied to monitoring failure investigations
Common Gaps
• Monitoring enabled but easily disabled by local users or admins
• No alerts configured for agent failures or loss of visibility
• Cloud instances launched without mandatory monitoring onboarding
• No response procedures tied to monitoring interruptions
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Enforcing continuous monitoring across all CUI-relevant systems
• Tracking the operational status of SIEM, EDR, and logging agents
• Alerting when monitoring failures or tampering events occur
• Linking enforcement evidence to your SSP and incident response records
• Providing real-time dashboards showing monitoring health and gaps
With Cuick Trac, your monitoring isn’t optional—it’s mandatory, protected, and proven.
Final CTA
Good detection is constant. Great detection is enforced.
