CMMC Physical Penetration Testing

What the Framework Requires

CMMC derives its physical protection requirements from NIST SP 800-171 and, by extension, NIST SP 800-53. The PE family covers physical access authorizations (who is allowed in), physical access control (how access is enforced), visitor access records (who was there), monitoring physical access (how access is tracked), and physical access control for transmission medium and output devices. For organizations at Level 2 and above, these controls must be implemented, documented, and assessed.

Defense contractors face a unique challenge. CUI may be present in offices, manufacturing floors, R&D labs, and testing facilities where physical security historically focused on perimeter access rather than information protection. An employee with a valid badge who can walk from their workstation to a CUI storage area without encountering additional access controls represents a gap that CMMC assessors will identify.

Organizations preparing for CMMC certification need to demonstrate that physical controls protecting CUI work in practice. A penetration test that targets CUI storage and processing locations, tests access controls under realistic conditions, and produces findings mapped to the PE family gives the assessor direct evidence of control effectiveness.

What We Test

• Physical access controls on all areas where CUI is stored, processed, or transmitted: secure rooms, server closets, manufacturing areas, R&D labs
• Badge and credential management: whether access privileges match authorization levels, whether terminated or changed roles result in prompt access revocation
• Visitor and contractor access: escort compliance, badge visibility, movement tracking, and whether visitors can reach CUI areas unescorted
• CUI marking and handling: physical documents, removable media, printed materials, and whether CUI is visible or accessible from unauthorized areas
• Manufacturing and production floor access: whether OT systems, test equipment, and engineering workstations with CUI are physically segregated from general access areas
• Social engineering against cleared and uncleared personnel: pretexting as contractors, IT support, or new employees to test security awareness around CUI protection
• After-hours and off-shift access: whether physical controls protecting CUI areas maintain effectiveness during reduced staffing
• Wireless and proximity exposure: whether networks carrying CUI are reachable from outside controlled areas, including parking lots, lobbies, and adjacent tenant spaces

The Crosswalk Advantage

CMMC PE controls derive directly from NIST SP 800-53, making the crosswalk to NIST RMF nearly one-to-one. Defense contractors who are also subject to NIST RMF (common for organizations with both DoD contracts and federal information system responsibilities) benefit from a single test plan that satisfies both frameworks. If the contractor also handles payment data or operates in healthcare, PCI DSS and HIPAA mapping can be layered onto the same engagement.

See how the same engagement satisfies NIST RMF, PCI DSS, and ISO 27001 requirements.

Which Tier Fits

Organizations preparing for CMMC Level 2 assessment should start with FOOTPRINT to identify physical security gaps before the assessor arrives. THRESHOLD delivers the physical penetration test with findings mapped to PE controls that assessors evaluate. STRONGHOLD is appropriate for organizations handling high-value CUI where realistic adversary simulation is needed to validate defense-in-depth. CADENCE provides ongoing evidence of physical control effectiveness for continuous monitoring requirements.
