SC-15(1) Physical or Logical Disconnect
Enhancement of: SC-15
High-Level Description
Family: System and Communications Protection (SC)
Framework: NIST SP 800-53 Rev 5
Failing to disconnect from collaborative computing devices can result in subsequent compromises of organizational information. Providing easy methods to disconnect from such devices after a collaborative computing session ensures that participants carry out the disconnect activity without having to go through complex and tedious procedures. Disconnect from collaborative computing devices can be manual or automatic.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SC-15(1) 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.
