NIST 800-171 3.8.6Implement cryptographic mechanisms to protect the confidentiality of CUI stored on digital media during transport unless otherwise protected by alternative physical safeguards
Overview
This control requires organizations to implement cryptographic mechanisms to protect the confidentiality of CUI stored on digital media during transport unless otherwise protected by alternative physical safeguards. It is part of the Media Protection family and is required for CMMC Level 2 certification. Defense contractors handling CUI must implement this control to protect sensitive information and demonstrate compliance during assessments.
Assessment Objectives
- 1Determine if the organization has defined policies and procedures to implement cryptographic mechanisms to protect the confidentiality of cui stored on digital media during transport unless otherwise protected by alternative physical safeguards
- 2Determine if the organization implements mechanisms to implement cryptographic mechanisms to protect the confidentiality of cui stored on digital media during transport unless otherwise protected by alternative physical safeguards
- 3Verify that the implementation is consistent with organizational policies and NIST 800-171 requirements
Implementation Guidance
Implement this control by establishing documented policies and procedures, deploying appropriate technical controls, and maintaining evidence of ongoing compliance. Regularly review and test the implementation to ensure effectiveness and address any gaps identified during assessments.
