Device Class 2: Media Transport

Control ID: MP-5 Media Transport	Family: Media Protection	Source: NIST 800-53r4
Control: The organization: Protects and controls [Assignment: organization-defined types of information system media] during transport outside of controlled areas using [Assignment: organization-defined security safeguards]; Maintains accountability for information system media during transport outside of controlled areas; Documents activities associated with the transport of information system media; and Restricts the activities associated with the transport of information system media to authorized personnel.
Supplemental Guidance: Information system media includes both digital and non-digital media. Digital media includes, for example, diskettes, magnetic tapes, external/removable hard disk drives, flash drives, compact disks, and digital video disks. Non-digital media includes, for example, paper and microfilm. This control also applies to mobile devices with information storage capability (e.g., smart phones, tablets, E-readers), that are transported outside of controlled areas. Controlled areas are areas or spaces for which organizations provide sufficient physical and/or procedural safeguards to meet the requirements established for protecting information and/or information systems. Physical and technical safeguards for media are commensurate with the security category or classification of the information residing on the media. Safeguards to protect media during transport include, for example, locked containers and cryptography. Cryptographic mechanisms can provide confidentiality and integrity protections depending upon the mechanisms used. Activities associated with transport include the actual transport as well as those activities such as releasing media for transport and ensuring that media enters the appropriate transport processes. For the actual transport, authorized transport and courier personnel may include individuals from outside the organization (e.g., U.S. Postal Service or a commercial transport or delivery service). Maintaining accountability of media during transport includes, for example, restricting transport activities to authorized personnel, and tracking and/or obtaining explicit records of transport activities as the media moves through the transportation system to prevent and detect loss, destruction, or tampering. Organizations establish documentation requirements for activities associated with the transport of information system media in accordance with organizational assessments of risk to include the flexibility to define different record-keeping methods for the different types of media transport as part of an overall system of transport-related records. In the case of C-ITS, this control applies to device design and related information developed during the development phase of a device's life cycle.

Control Enhancements: (4) Media Transport \| Cryptographic Protection The information system implements cryptographic mechanisms to protect the confidentiality and integrity of information stored on digital media during transport outside of controlled areas. Supplemental Guidance: This control enhancement applies to both portable storage devices (e.g.,USB memory sticks, compact disks, digital video disks, external/removable hard disk drives) and mobile devices with storage capability (e.g., smart phones, tablets, E-readers). Related Controls: MP-2

Mechanisms: Any data transmitted to a mobile device with storage capabilities will do so over an encrypted communication channel consistent with latest cryptographic best practices Any portable media storage with sensitive information on it will be fully encrypted while it is being transported.
