SC-7(24) Personally Identifiable Information
Enhancement of: SC-7
High-Level Description
Family: System and Communications Protection (SC) Framework: NIST SP 800-53 Rev 5
Managing the processing of personally identifiable information is an important aspect of protecting an individual’s privacy. Applying, monitoring for, and documenting exceptions to processing rules ensure that personally identifiable information is processed only in accordance with established privacy requirements.
What to Check
- Verify SC-7(24) Personally Identifiable Information is documented in SSP
- Validate all 4 control requirements are implemented
- Confirm control is operating effectively
- Review evidence of continuous monitoring for SC-7(24)
- Verify enhancement builds upon base control SC-7
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SC-7(24) 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 encryption and network controls | cloud_audit_encryption |
| nmap | Network scanning | nmap -sV --script ssl-enum-ciphers |
Remediation Guide
Control Statement
For systems that process personally identifiable information: Apply the following processing rules to data elements of personally identifiable information: [organization-defined]; Monitor for permitted processing at the external interfaces to the system and at key internal boundaries within the system; Document each processing exception; and Review and remove exceptions that are no longer supported.
Implementation Guidance
Managing the processing of personally identifiable information is an important aspect of protecting an individual’s privacy. Applying, monitoring for, and documenting exceptions to processing rules ensure that personally identifiable information is processed only in accordance with established privacy requirements.
