Wireless Access (03.01.16) Wireless Access

High-Level Description

Family: Access Control Framework: NIST SP 800-171 Rev 3 Applicability: Systems processing, storing, or transmitting CUI

Establish usage restrictions, configuration requirements, and connection requirements for each type of wireless access to the system. Authorize each type of wireless access to the system prior to establishing such connections. Disable, when not intended for use, wireless networking capabilities prior to issuance and deployment. Protect wireless access to the system using authentication and encryption.

What to Check

• Verify Wireless Access (03.01.16) Wireless Access is implemented for CUI systems
• Review SSP documentation for Wireless Access (03.01.16)
• Validate CMMC Level 2 assessment objective for Wireless Access (03.01.16)
• Confirm POA&M addresses any gaps for Wireless Access (03.01.16)

How to Test

Step 1: Review System Security Plan

Examine the SSP for Wireless Access (03.01.16) implementation description and responsible parties.

Step 2: Assess Implementation

# Verify security controls protecting CUI
# Check access controls, encryption, monitoring as applicable

# For Linux systems:
ls -la /etc/security/ 2>/dev/null
grep -r "CUI\|controlled" /etc/security/ 2>/dev/null

# For cloud:
# Use cloud-audit-mcp tools to assess posture

Step 3: CMMC Assessment Validation

Verify this requirement passes CMMC Level 2 assessment methodology per SP 800-171A Rev 3.

Requirement Statement

Establish usage restrictions, configuration requirements, and connection requirements for each type of wireless access to the system. Authorize each type of wireless access to the system prior to establishing such connections. Disable, when not intended for use, wireless networking capabilities prior to issuance and deployment. Protect wireless access to the system using authentication and encryption.

Supplemental Guidance

Wireless networking capabilities represent a significant potential vulnerability that can be exploited by adversaries. Establishing usage restrictions, configuration requirements, and connection requirements for wireless access to the system provides criteria to support access authorization decisions. These restrictions and requirements reduce susceptibility to unauthorized system access through wireless technologies. Wireless networks use authentication protocols that provide credential protection and mutual authentication. Organizations authenticate individuals and devices to protect wireless access to the system. Special attention is given to the variety of devices with potential wireless access to the system, including small form factor mobile devices (e.g., smart phones, tablets, smart watches). Wireless networking capabilities that are embedded within system components represent a potential vulnerability that can be exploited by adversaries. Strong authentication of users and devices, strong encryption, and disabling wireless capabilities that are not needed for essential mission or business functions can reduce susceptibility to threats by adversaries involving wireless technologies.
