What is NIST 800-171 Control 3.10.2?
This control ensures your facility—and the infrastructure supporting your IT systems—is secured against physical threats like:
• Unauthorized access
• Theft or tampering
• Environmental hazards (e.g., flooding, overheating)
It applies to:
• Data centers and server rooms
• Network closets
• Electrical, HVAC, and utility access points
• Entryways, windows, and surrounding areas
Why It Matters
Even a well-secured network can be compromised if someone has physical access to the wiring closet or can cut power or HVAC to your systems.
Monitoring your facilities protects you against:
• Insider threats
• Social engineering (tailgating into restricted areas)
• Physical sabotage
How to Implement It
• Use surveillance systems (e.g., cameras, sensors) to monitor sensitive areas
• Deploy alarms or alerts for unauthorized access attempts
• Control and restrict physical access to networking and infrastructure zones
• Monitor environmental factors (e.g., temperature, humidity) in server rooms
• Regularly inspect locks, doors, cameras, and access logs
Common Mistakes
• Leaving physical infrastructure exposed in shared spaces
• Not reviewing security camera footage or access logs
• Assuming cloud providers handle all physical concerns (they don’t for hybrid environments)
How Cuick Trac Helps
Cuick Trac supports this control by:
• Reducing physical infrastructure requirements through its cloud-hosted CUI enclave
• Providing best practices for securing hybrid and on-prem environments
• Helping teams document physical security measures for audit readiness
• Offering templates for monitoring procedures and facility access records
With Cuick Trac, your digital and physical defenses work together to protect CUI from all angles.
Final CTA
If it powers or connects to CUI, protect it like the data itself.
