In CMMC 2.0, why are physical access controls essential at physical locations?

Physical access controls are essential at physical locations to protect systems that process, store, or transmit Controlled Unclassified Information (CUI) from unauthorized access. This is a core requirement of CMMC 2.0, as safeguarding sensitive information is crucial for maintaining national security and ensuring the integrity of data.

By implementing physical access controls, organizations can restrict entry to authorized personnel only. This minimizes the risk of insider threats and external breaches, thereby enhancing the overall security posture of physical systems. These controls can include measures like locked doors, security personnel, surveillance cameras, and access control systems that require identification or authentication.

This focus on protecting CUI aligns with the broader goals of the Cybersecurity Maturity Model Certification framework, which emphasizes the need for robust protection of sensitive data in all environments where it may be handled, processed, or stored. The presence of these controls not only protects the data but also helps organizations demonstrate compliance with federal regulations regarding data security.
