Limit Physical Access to Authorized Individuals

CMMC-RP Certified Team 24+ Years Experience 2,500+ Clients Served

Official Requirement

Limit physical access to organizational information systems, equipment, and the respective operating environments to authorized individuals.

What This Means in Plain English

Only authorized people should be able to physically enter areas where your IT systems are located. Server rooms, network closets, and data centers must have access controls preventing unauthorized entry.

How Petronella Implements This Control

Petronella Technology Group implements this control through:

  • Badge access control systems on all server rooms, network closets, and CUI processing areas
  • Visitor management system requiring sign-in and escort for all non-employees
  • Security cameras monitoring all physical entry points to IT areas
  • Physical access logs reviewed weekly for anomalies
  • ComplianceArmor maintaining the list of personnel authorized for each restricted area

Assessment Guidance

Assessors will test physical access controls, verify that unauthorized individuals cannot enter restricted areas, review physical access logs, check security camera coverage, and confirm that authorized access lists are current.

Common Implementation Gaps

  • Server rooms without badge access or locks
  • Tailgating not addressed (people following authorized individuals through doors)
  • No visitor management system
  • Physical access logs not reviewed
  • Wiring closets and network equipment in accessible areas
