SI-10(6) Injection Prevention

Enhancement of: SI-10

High-Level Description

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

Untrusted data injections may be prevented using a parameterized interface or output escaping (output encoding). Parameterized interfaces separate data from code so that injections of malicious or unintended data cannot change the semantics of commands being sent. Output escaping uses specified characters to inform the interpreter’s parser whether data is trusted. Prevention of untrusted data injections are with respect to the information inputs defined by the organization in the base control ( SI-10).

What to Check

• Verify SI-10(6) Injection Prevention is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SI-10(6)
• 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(6) 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.
