In the context of a Cybersecurity Maturity Model Certification (CMMC) Level 2 Assessment, specific practices must be evaluated to ensure compliance with established security requirements. One such practice is AC.L2-3.1.19, which mandates the encryption of Controlled Unclassified Information (CUI) on mobile devices and mobile computing platforms.
Step-by-Step Explanation:
Requirement Overview:
Practice AC.L2-3.1.19 requires organizations to "Encrypt CUI on mobile devices and mobile computing platforms." This ensures that any CUI accessed, stored, or transmitted via mobile devices is protected through encryption, mitigating risks associated with data breaches or unauthorized access.
Assessment of Provided Evidence:
During the assessment, the Organization Seeking Certification (OSC) provided an inventory list encompassing servers, workstations, and network devices. Notably, this list lacks any mention of mobile devices or mobile computing platforms.
Implications of the Omission:
The absence of mobile devices in the inventory suggests that the OSC may not have accounted for all assets that process, store, or transmit CUI. Without a comprehensive inventory that includes mobile devices, it's challenging to verify whether the OSC has implemented the necessary encryption measures for CUI on these platforms.
Assessment Determination:
Given the incomplete inventory, the evidence is insufficient to make a definitive scoring determination for practice AC.L2-3.1.19. The OSC must provide a detailed inventory that encompasses all relevant devices, including mobile devices and computing platforms, to demonstrate compliance with the encryption requirements for CUI.
