03.13.08 Transmission and Storage Confidentiality

Statement

Implement cryptographic mechanisms to prevent the unauthorized disclosure of CUI during transmission and while in storage.

Guidance

This requirement applies to internal and external networks and any system components that can transmit CUI, including servers, notebook computers, desktop computers, mobile devices, printers, copiers, scanners, facsimile machines, and radios. Unprotected communication paths are susceptible to interception and modification. Encryption protects CUI from unauthorized disclosure during transmission and while in storage. Cryptographic mechanisms that protect the confidentiality of CUI during transmission include TLS and IPsec. Information in storage (i.e., information at rest) refers to the state of CUI when it is not in process or in transit and resides on internal or external storage devices, storage area network devices, and databases. Protecting CUI in storage does not focus on the type of storage device or the frequency of access to that device but rather on the state of the information. This requirement relates to [](#/cprt/framework/version/SP_800_171_3_0_0/home?element=03.13.11) 03.13.11.
