What is NIST 800-171 Control 3.10.1?
This control requires you to control who can physically access:
• Computers and servers that handle CUI
• Network equipment (e.g., routers, switches)
• Backup storage
• Any area where CUI is processed, printed, stored, or displayed
Access must be restricted to individuals with authorized, documented need.
Why It Matters
Even with the strongest digital protections, physical access can bypass everything:
• An attacker or insider can steal drives or plug in malicious USBs
• A visitor can see or photograph sensitive information
• Unauthorized individuals can tamper with equipment
Limiting physical access is your first line of defense—especially in shared facilities or hybrid environments.
How to Implement It
• Secure CUI-handling systems in locked rooms, cages, or enclosures
• Use badges, PINs, or biometrics for physical access control
• Maintain an up-to-date list of authorized personnel
• Log and monitor access to secure areas
• Review access regularly and revoke when no longer needed
Common Mistakes
• Leaving server rooms or offices unlocked or unattended
• Failing to revoke access when someone leaves the company
• Assuming front desk sign-in sheets are enough for visitor tracking
