SI-10(1)_manual-override-capability

SI-10(1) Manual Override Capability

Enhancement of: SI-10

High-Level Description

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

In certain situations, such as during events that are defined in contingency plans, a manual override capability for input validation may be needed. Manual overrides are used only in limited circumstances and with the inputs defined by the organization.

What to Check

• Verify SI-10(1) Manual Override Capability is documented in SSP
• Validate all 3 control requirements are implemented
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SI-10(1)
• Verify enhancement builds upon base control SI-10

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SI-10(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

Provide a manual override capability for input validation of the following information inputs: [organization-defined]; Restrict the use of the manual override capability to only [organization-defined] ; and Audit the use of the manual override capability.

Implementation Guidance

In certain situations, such as during events that are defined in contingency plans, a manual override capability for input validation may be needed. Manual overrides are used only in limited circumstances and with the inputs defined by the organization.
