What is NIST 800-171 Control 3.11.3?
Control 3.11.3 is the natural follow-up to 3.11.2. After you scan for vulnerabilities, you must:
• Evaluate their risk (based on severity, exploitability, impact)
• Remediate them in a timely manner
• Track and document remediation actions
• Reassess to ensure the fix was effective
This ensures that vulnerabilities affecting Controlled Unclassified Information (CUI) are addressed in a way that’s aligned with your risk posture.
Why It Matters
Finding a vulnerability is only half the battle—fixing it appropriately and quickly is what really reduces risk.
This control helps ensure that:
• High-risk issues are addressed first
• Remediation isn’t delayed or deprioritized
• You’re not treating all vulnerabilities equally when they aren’t
How to Implement It
• Tie vulnerability findings into your risk management program
• Classify findings by:
◦ CVSS score
◦ Business impact
◦ Likelihood of exploitation
• Assign risk-based remediation timelines (e.g., critical = 48 hours)
• Assign ownership and track progress in a ticketing or tracking system
• Perform follow-up scans to confirm resolution
Common Mistakes
• Fixing easy issues first while critical ones linger
• Treating scanning and remediation as separate processes
• Not documenting remediation steps or timelines for audits
