SI.L2-3.14.1[b]: Document How You Monitor Your Systems for Threats and Protect CUI

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

What This Control Means
After identifying your system monitoring tools and techniques (SI.L2-3.14.1[a]), this objective ensures you record them properly in your security documentation—typically in your:
• System Security Plan (SSP)
• Security operations documentation
• Monitoring and incident response procedures
You must connect your technical solutions to an intentional monitoring strategy.

Why It Matters
Without documentation:
• Auditors can’t verify you’re monitoring CUI-related systems properly
• Internal teams may implement inconsistent monitoring practices
• Threat detection could be incomplete or misaligned
• Alerts may be missed, misunderstood, or unhandled
Documented monitoring ensures clear, consistent coverage of threats and vulnerabilities.

How to Implement It
1. Update the SSP and Security Policies Document:
• What systems are monitored
• Which monitoring tools are deployed
• What types of threats or indicators are tracked (e.g., unauthorized logins, malware alerts)
• Where monitoring occurs (e.g., endpoints, servers, cloud platforms)
2. Include Monitoring Scope and Responsibilities
• Who is responsible for:
◦ Reviewing logs and alerts
◦ Responding to suspicious activity
◦ Updating monitoring configurations
3. Reference Monitoring Tools Examples:
• Firewalls and perimeter monitoring
• SIEM platforms like Splunk, LogRhythm, SentinelOne
• Endpoint protection and EDR solutions
• Cloud-native security monitoring (AWS CloudTrail, Azure Sentinel)
4. Map Monitoring to CUI Systems
• Highlight which CUI systems are under monitoring
• Describe special considerations for CUI-specific alerts and incidents

Evidence the Assessor Will Look For
• SSP entries or security plans describing system monitoring mechanisms
• Policy or procedure documents outlining monitoring responsibilities
• Configuration screenshots from monitoring tools (e.g., SIEM dashboards, IDS rules)
• Network diagrams highlighting monitoring coverage areas
• Logs showing monitoring activity on CUI-relevant systems

Common Gaps
• Monitoring in place but no documentation describing it
• Only perimeter or antivirus monitoring documented—no endpoint or cloud monitoring
• Monitoring responsibilities undefined or informally assigned
• SSP mentions “monitoring” but without naming specific tools or systems

How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Documenting all system monitoring tools, coverage, and responsibilities
• Mapping monitoring activities to your CUI systems and data flows
• Linking monitoring to your incident response procedures and escalation workflows
• Generating audit-ready records of your monitoring strategy and implementation
• Keeping monitoring documentation synchronized with real-world security operations
With Cuick Trac, your monitoring defenses are not just active—they’re documented, coordinated, and audit-ready.

Final CTA
Good monitoring detects attacks—great documentation proves you’re ready for them.
Schedule a Cuick Trac demo to document your threat monitoring strategy and secure your CUI environment with confidence.
