What is NIST 800-171 Control 3.10.5?
This control is about managing the security of physical access systems themselves, including:
• Card readers and keypads
• Security badges and key fobs
• Physical keys or lock combinations
• Biometric devices
You must control who issues, configures, and maintains these devices—and ensure only approved individuals can use them to access areas containing Controlled Unclassified Information (CUI).
Why It Matters
If the tools that control access are not secure, then your physical protections are meaningless. Examples of risks include:
• Lost or stolen badges that are still active
• PINs shared informally among staff
• Unmonitored admin access to badge systems
This control ensures that access control systems don’t become a vulnerability.
How to Implement It
• Maintain an inventory of all physical access control devices
• Assign and track who has access to each device or method
• Immediately disable lost, stolen, or terminated access credentials
• Review and rotate lock codes or PINs periodically
• Limit administrative access to systems that control physical access
• Log any changes to access control systems (e.g., new badge issued, PIN updated)
Common Mistakes
• Not deactivating badges when employees leave
• Failing to rotate PINs or lock combinations
• Letting multiple users share the same physical access method
How Cuick Trac Helps
Cuick Trac supports this control by:
• Reducing the need for physical access through secure remote CUI access
• Offering templates and guidance for access device tracking and revocation policies
• Helping teams align badge systems and logs with NIST and CMMC compliance requirements
• Supporting audit readiness with documentation for physical control system administration
With Cuick Trac, access control devices are secured—just like the systems they protect.
Final CTA
A secure badge system isn’t enough if it’s not managed securely.
Book a Cuick Trac demo and make your physical access devices a strength—not a soft spot.
