Mapped to NIST 800-171 Requirement: 3.14.3
CMMC Assessment Objective: SI.L2-3.14.3[c]
What This Control Means
This is the operational validation checkpoint.
You must show that:
• Vulnerability scans are performed on CUI systems
• System and application flaws are detected regularly
• Threat advisories are monitored and new vulnerabilities are assessed
• Flaw identification activities are ongoing—not a one-time event
Assessment teams will want to see real, recent evidence of vulnerability detection.
Why It Matters
Without active flaw identification:
• Vulnerabilities may persist for months or years, exposing CUI
• Systems may remain outdated and unpatched against known exploits
• You will fail key NIST 800-171, CMMC, or DFARS compliance requirements
• Attackers will have opportunities to exploit gaps you aren’t even watching
Active flaw identification is fundamental to proactive security management.
How to Implement It
1. Schedule and Perform Regular Vulnerability Scans
• At least quarterly (or more frequently for critical systems)
• After major system changes, updates, or new deployments
• Cover endpoints, servers, networks, and cloud infrastructure
2. Monitor External Threat Feeds
• Watch:
◦ CISA KEV Catalog
◦ Vendor security advisories (Microsoft, Cisco, etc.)
◦ CVE announcements from the NVD (National Vulnerability Database)
3. Track Discovered Vulnerabilities
• Maintain a vulnerability register listing:
◦ System or app impacted
◦ Flaw description and CVE ID
◦ Severity score (e.g., CVSS)
◦ Planned or completed remediation actions
4. Prioritize and Remediate
• Focus first on high/critical vulnerabilities affecting CUI systems
Evidence the Assessor Will Look For
• Recent vulnerability scan reports showing discovered flaws
• Threat intelligence feeds and alert subscription records
• Lists of known vulnerabilities tracked internally
• Logs showing scans were scheduled, completed, and reviewed
• Incident records triggered by discovered vulnerabilities
Common Gaps
• Scans scheduled but inconsistently performed
• Only OS or network vulnerabilities monitored—no application layer scanning
• Cloud platforms not covered by flaw identification tools
• No follow-up or tracking for discovered vulnerabilities
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Tracking real-time vulnerability scans and flaw identification across your environment
• Logging flaw discovery events tied to CUI systems
• Monitoring threat feeds and vendor alerts for emerging risks
• Linking discovered vulnerabilities to risk and remediation workflows
• Providing audit-ready evidence that flaw identification is continuous and targeted
With Cuick Trac, you don’t just talk about vulnerability management—you live it, track it, and prove it.
