SC-15(3) Disabling and Removal in Secure Work Areas

Enhancement of: SC-15

High-Level Description

Family: System and Communications Protection (SC) Framework: NIST SP 800-53 Rev 5

Failing to disable or remove collaborative computing devices and applications from systems or system components can result in compromises of information, including eavesdropping on conversations. A Sensitive Compartmented Information Facility (SCIF) is an example of a secure work area.

What to Check

• Verify SC-15(3) Disabling and Removal in Secure Work Areas is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SC-15(3)
• Verify enhancement builds upon base control SC-15

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SC-15(3) implementation details. Verify the organization has documented how this control is satisfied.

Step 2: Validate Implementation

# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly

# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null

Step 3: Test Operating Effectiveness

Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.
