SI.L2-3.14.1[c]: Prove That Your Monitoring Systems Are Actively Protecting CUI

Mapped to NIST 800-171 Requirement: 3.14.1
CMMC Assessment Objective: SI.L2-3.14.1[c]

What This Control Means
This is the operational validation checkpoint.
You must show that:
• Monitoring tools (e.g., SIEMs, IDS/IPS, EDR solutions) are running and generating alerts
• Monitoring coverage includes CUI systems, cloud platforms, endpoints, and boundaries
• Threats and anomalies are detected, logged, and escalated as part of daily operations
Assessors want proof that your monitoring is real, active, and protecting your CUI environment.

Why It Matters
Without active monitoring:
• Malware infections, data exfiltration, or unauthorized access attempts may go unnoticed
• Insider threats could exploit unmonitored paths
• You’ll fail the technical validation portions of your CMMC or DFARS compliance reviews
• Your incident detection and response capabilities will be critically weakened
Security is proactive visibility—not reactive assumptions.

How to Implement It
1. Validate Monitoring Tools Are Active
• Ensure SIEMs, IDS/IPS, endpoint protection, cloud monitors are collecting and analyzing logs
• Confirm event correlation and alerting are enabled
2. Confirm Coverage Across the Environment
• Include:
◦ Workstations and servers handling CUI
◦ Remote access points (e.g., VPN, cloud consoles)
◦ Boundary devices (e.g., firewalls, proxy servers)
◦ Cloud environments and SaaS platforms
3. Review Active Alerts and Logs
• Show recent threat detections, investigations, and remediation actions
4. Audit Monitoring Policies
• Confirm all critical systems are onboarded to your monitoring platforms
• Validate that suspicious activities trigger automated alerts

Evidence the Assessor Will Look For
• Live dashboards or screenshots from SIEM, IDS/IPS, or EDR platforms
• Monitoring coverage reports listing CUI systems
• Logs showing detected anomalies, alerts, or incidents
• Policies or procedures for event logging and alert escalation
• Incident response records triggered by monitoring tools

Common Gaps
• Monitoring tools deployed but not configured or active
• Only network monitoring active—no endpoint or cloud monitoring
• No alert thresholds defined, or alerts ignored/missed
• CUI systems not included in active monitoring coverage

How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Tracking and verifying that monitoring systems are live and actively analyzing CUI systems
• Logging and linking detection events to CUI system inventories
• Alerting on gaps in monitoring coverage or missed threat detection
• Integrating monitoring results with your SSP, POA&M, and risk assessments
• Providing audit-ready proof of continuous monitoring activities across your environment
With Cuick Trac, your monitoring is more than deployed—it’s validated, enforced, and always watching.

Final CTA
Visibility is the difference between reacting to a breach—and preventing it.
Schedule a Cuick Trac demo to validate your monitoring strategy and ensure your CUI defenses are always on guard.
