Mapped to NIST 800-171 Requirement: 3.1.14
CMMC Assessment Objective: AC.L2-3.1.14[b]
What This Objective Means
While AC.L2-3.1.14[a] focuses on identifying and documenting wireless restrictions, this objective requires you to prove they are enforced through system and network configuration.
That means assessors will examine whether:
• Systems are configured to prevent unauthorized wireless connections
• Wireless networks are segmented or isolated from CUI environments
• Encryption protocols like WPA2/WPA3 or FIPS-validated AES are enforced
• Wireless devices and access points are configured according to policy
Why It Matters
It’s not enough to define wireless restrictions—they must be actively applied and enforced. Misconfigurations, legacy equipment, or shadow networks can expose CUI and create audit failure points.
How to Implement It
• Configure wireless access points to:
◦ Use strong encryption (WPA2 Enterprise or higher, FIPS-validated)
◦ Restrict access to authorized devices only (via MAC filtering, certificates, or 802.1X)
◦ Disable SSID broadcasting for administrative or secure segments
◦ Limit signal range where possible
• Use VLANs or firewalls to isolate wireless traffic from CUI systems
• Disable Wi-Fi adapters on systems designated for CUI processing if wireless is not approved
• Monitor for unauthorized or rogue wireless access points
Evidence the Assessor Will Look For
• Wireless controller or access point settings showing enforcement of:
◦ Authentication
◦ Encryption
◦ Access controls
• Screenshots of endpoint configurations (e.g., Wi-Fi disabled on CUI laptops)
• Network topology or segmentation diagrams
• Logs from wireless intrusion detection/prevention systems (WIDS/WIPS)
• Documentation that aligns technical settings with policy restrictions
Common Gaps
• Policy restricts wireless access, but enforcement is inconsistent or missing
• Legacy WAPs using outdated or weak encryption (e.g., WEP, WPA)
• No documentation or confirmation of network segmentation for CUI traffic
How Cuick Trac Helps
Cuick Trac supports enforcement of wireless access restrictions by:
• Centralizing CUI systems within a wired, controlled enclave
• Helping organizations identify and configure wireless security controls
• Offering advisory support for enforcing wireless segmentation and access limits
• Providing policy and configuration documentation aligned with CMMC audit requirements
With Cuick Trac, wireless access to CUI systems is either blocked or protected by design—not left to chance.
Final CTA
Restrictions mean little without enforcement.
