SC-29(1)_virtualization-techniques

SC-29(1) Virtualization Techniques

Enhancement of: SC-29

High-Level Description

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

While frequent changes to operating systems and applications can pose significant configuration management challenges, the changes can result in an increased work factor for adversaries to conduct successful attacks. Changing virtual operating systems or applications, as opposed to changing actual operating systems or applications, provides virtual changes that impede attacker success while reducing configuration management efforts. Virtualization techniques can assist in isolating untrustworthy software or software of dubious provenance into confined execution environments.

What to Check

• Verify SC-29(1) Virtualization Techniques is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SC-29(1)
• Verify enhancement builds upon base control SC-29

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SC-29(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.

Control Statement

Employ virtualization techniques to support the deployment of a diversity of operating systems and applications that are changed [organization-defined].

Changing virtual operating systems or applications, as opposed to changing actual operating systems or applications, provides virtual changes that impede attacker success while reducing configuration management efforts.
