SC-2(1) Interfaces for Non-privileged Users

Enhancement of: SC-2

High-Level Description

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

Preventing the presentation of system management functionality at interfaces to non-privileged users ensures that system administration options, including administrator privileges, are not available to the general user population. Restricting user access also prohibits the use of the grey-out option commonly used to eliminate accessibility to such information. One potential solution is to withhold system administration options until users establish sessions with administrator privileges.

What to Check

• Verify SC-2(1) Interfaces for Non-privileged Users is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SC-2(1)
• Verify enhancement builds upon base control SC-2

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SC-2(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.
