Mapped to NIST 800-171 Requirement: 3.1.15
CMMC Assessment Objective: AC.L2-3.1.15[c]
What This Objective Means
This is the technical enforcement check for wireless encryption. The assessor will look at your system and network configurations to verify that:
• Wireless encryption is actually enabled
• The configured protocol matches the one required in your policies (e.g., WPA2-Enterprise or WPA3 with AES)
• All wireless access points and devices consistently apply these settings
It’s not enough to require encryption in your policy—you must prove it’s in place and active.
Why It Matters
If wireless encryption isn’t enforced at the system level:
• Attackers could intercept data transmitted over unprotected or weakly protected wireless networks
• CUI could be exposed to unauthorized users
• You’ll fail audit requirements under CMMC Level 2 or NIST 800-171
Encryption enforcement protects the confidentiality and integrity of data in motion.
How to Implement It
• Access your wireless controllers or individual WAP interfaces to verify settings
• Confirm:
◦ WPA2-Enterprise or WPA3 is enabled
◦ AES or another FIPS 140-2 validated encryption method is selected
◦ TKIP, WEP, or open networks are disabled
• Ensure these settings are applied consistently across:
◦ Internal access points
◦ Guest networks
◦ Remote/branch office WAPs
• Validate that endpoint devices connecting to these networks also require secure encryption
Evidence the Assessor Will Look For
• Screenshots or configuration exports from wireless access points or controllers
• Encryption protocol and key management settings
• Confirmation that outdated encryption protocols are disabled
• Test results showing successful connection only via encrypted protocols
Common Gaps
• Policy requires encryption but WAPs are still using WPA-Personal or WEP
• Guest or secondary networks are misconfigured or unmonitored
• Encryption only applied to some access points or locations
How Cuick Trac Helps
Cuick Trac supports this control by:
• Eliminating the need for wireless access to CUI systems by using secure wired enclave models
• Helping organizations configure and document wireless encryption settings for external access points
• Providing enforcement templates and best practice configurations for wireless security
• Supporting encryption validation through advisory and audit-ready documentation
With Cuick Trac, wireless encryption is either enforced—or wireless access to CUI is eliminated altogether.
Final CTA
If the encryption isn’t active, the protection isn’t real.
