Mapped to NIST 800-171 Requirement: 3.14.3
CMMC Assessment Objective: SI.L2-3.14.3[d]
What This Control Means
This is the remediation checkpoint.
You must show that:
• Discovered flaws are tracked to closure
• Systems and applications are patched or mitigated promptly
• Risk-based prioritization drives which flaws are addressed first
• Critical vulnerabilities are not left unaddressed
Finding vulnerabilities isn’t enough—you must fix them in a timely and structured manner.
Why It Matters
Without remediation:
• CUI remains exposed to threats even after vulnerabilities are discovered
• Attackers can exploit known flaws if left open
• Your vulnerability management program will fail compliance audits
• System integrity and trust are weakened
Security depends not just on detection—but on action.
How to Implement It
1. Track Each Discovered Vulnerability
• Maintain a vulnerability register that logs:
◦ Flaw description and system impact
◦ Assigned risk rating (critical, high, medium, low)
◦ Assigned owner and due date for remediation
2. Apply Timely Patching or Mitigation
• Set internal Service Level Agreements (SLAs) based on severity:
◦ Critical: patched within 15 days
◦ High: patched within 30 days
◦ Medium/Low: patched as prioritized
3. Use Risk-Based Prioritization
• Address vulnerabilities impacting CUI systems first
• Mitigate if immediate patching isn’t possible (e.g., firewall rules, application controls)
4. Validate and Retest
• Scan again after patching to verify closure
• Document closure status in your vulnerability register or POA&M
5. Include in POA&M if Necessary
• If a flaw can’t be immediately fixed, record it with planned mitigation timelines
Evidence the Assessor Will Look For
• Updated vulnerability registers showing closure status
• Patch deployment records and reports
• Screenshots or logs confirming flaw remediation
• POA&M entries tracking unresolved vulnerabilities
• Incident response records showing flaw-driven mitigation actions
Common Gaps
• Vulnerabilities identified but not addressed in a timely manner
• No formal tracking of remediation activities
• Patching done inconsistently or informally without documentation
• Critical flaws left unaddressed due to lack of prioritization
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Tracking vulnerability remediation status across your systems
• Logging patch deployments, mitigation steps, and verification scans
• Prioritizing vulnerabilities affecting CUI systems first
• Alerting on overdue remediation deadlines
• Maintaining an audit-ready record of detection, action, and closure
With Cuick Trac, flaws don’t just get found—they get fixed, tracked, and proven secure.
Final CTA
Finding flaws is important—fixing them is mandatory.
