SI-13(3) Manual Transfer Between Components

Enhancement of: SI-13

High-Level Description

Family: System and Information Integrity (SI) Framework: NIST SP 800-53 Rev 5

For example, if the MTTF for a system component is 100 days and the MTTF percentage defined by the organization is 90 percent, the manual transfer would occur after 90 days.

What to Check

• Verify SI-13(3) Manual Transfer Between Components is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SI-13(3)
• Verify enhancement builds upon base control SI-13

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SI-13(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.

Control Statement

Manually initiate transfers between active and standby system components when the use of the active component reaches [organization-defined] of the mean time to failure.

Implementation Guidance

For example, if the MTTF for a system component is 100 days and the MTTF percentage defined by the organization is 90 percent, the manual transfer would occur after 90 days.
