cyberstrikeus MP-7(2) Prohibit Use of Sanitization-resistant Media
Enhancement of: MP-7
High-Level Description
Family: Media Protection (MP) Framework: NIST SP 800-53 Rev 5
Sanitization resistance refers to how resistant media are to non-destructive sanitization techniques with respect to the capability to purge information from media. Certain types of media do not support sanitization commands, or if supported, the interfaces are not supported in a standardized way across these devices. Sanitization-resistant media includes compact flash, embedded flash on boards and devices, solid state drives, and USB removable media.
What to Check
- Verify MP-7(2) Prohibit Use of Sanitization-resistant Media is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for MP-7(2)
- Verify enhancement builds upon base control MP-7
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for MP-7(2) 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.
