AC-4(32) Process Requirements for Information Transfer
Enhancement of: AC-4
High-Level Description
Family: Access Control (AC)
Framework: NIST SP 800-53 Rev 5
The processes transferring information between filter pipelines have minimum complexity and functionality to provide assurance that the processes operate correctly.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AC-4(32) 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.
Tools
| Tool | Purpose | Usage |
|---|
| cloud-audit-mcp | Check IAM policies and access controls | cloud_audit_iam_policies |
| hackbrowser-mcp | Test web application access controls | browser_auth_test |
Remediation Guide
Control Statement
When transferring information between different security domains, the process that transfers information between filter pipelines:
Does not filter message content;
Validates filtering metadata;
Ensures the content associated with the filtering metadata has successfully completed filtering; and
Transfers the content to the destination filter pipeline.
