NIST Media Protection Risk Controls (mp)

Policy and Procedures (mp-1)

Develop, document, and disseminate to organization-defined personnel or roles:

one or more,Organization-level,Mission/business process-level,System-level media protection policy that:

Addresses purpose, scope, roles, responsibilities, management commitment, coordination among organizational entities, and compliance; and

Is consistent with applicable laws, executive orders, directives, regulations, policies, standards, and guidelines; and

Procedures to facilitate the implementation of the media protection policy and the associated media protection controls;

Designate an organization-defined official to manage the development, documentation, and dissemination of the media protection policy and procedures; and

Review and update the current media protection:

Policy organization-defined frequency and following organization-defined events; and

Procedures organization-defined frequency and following organization-defined events.

Media protection policy and procedures address the controls in the MP family that are implemented within systems and organizations. The risk management strategy is an important factor in establishing such policies and procedures. Policies and procedures contribute to security and privacy assurance. Therefore, it is important that security and privacy programs collaborate on the development of media protection policy and procedures. Security and privacy program policies and procedures at the organization level are preferable, in general, and may obviate the need for mission- or system-specific policies and procedures. The policy can be included as part of the general security and privacy policy or be represented by multiple policies that reflect the complex nature of organizations. Procedures can be established for security and privacy programs, for mission or business processes, and for systems, if needed. Procedures describe how the policies or controls are implemented and can be directed at the individual or role that is the object of the procedure. Procedures can be documented in system security and privacy plans or in one or more separate documents. Events that may precipitate an update to media protection policy and procedures include assessment or audit findings, security incidents or breaches, or changes in applicable laws, executive orders, directives, regulations, policies, standards, and guidelines. Simply restating controls does not constitute an organizational policy or procedure.

Media Access (mp-2)

Restrict access to organization-defined types of digital and/or non-digital media to organization-defined personnel or roles.

System media includes digital and non-digital media. Digital media includes flash drives, diskettes, magnetic tapes, external or removable hard disk drives (e.g., solid state, magnetic), compact discs, and digital versatile discs. Non-digital media includes paper and microfilm. Denying access to patient medical records in a community hospital unless the individuals seeking access to such records are authorized healthcare providers is an example of restricting access to non-digital media. Limiting access to the design specifications stored on compact discs in the media library to individuals on the system development team is an example of restricting access to digital media.

Media Sanitization (mp-6)

Sanitize organization-defined system media prior to disposal, release out of organizational control, or release for reuse using organization-defined sanitization techniques and procedures; and

Employ sanitization mechanisms with the strength and integrity commensurate with the security category or classification of the information.

Media sanitization applies to all digital and non-digital system media subject to disposal or reuse, whether or not the media is considered removable. Examples include digital media in scanners, copiers, printers, notebook computers, workstations, network components, mobile devices, and non-digital media (e.g., paper and microfilm). The sanitization process removes information from system media such that the information cannot be retrieved or reconstructed. Sanitization techniques?including clearing, purging, cryptographic erase, de-identification of personally identifiable information, and destruction?prevent the disclosure of information to unauthorized individuals when such media is reused or released for disposal. Organizations determine the appropriate sanitization methods, recognizing that destruction is sometimes necessary when other methods cannot be applied to media requiring sanitization. Organizations use discretion on the employment of approved sanitization techniques and procedures for media that contains information deemed to be in the public domain or publicly releasable or information deemed to have no adverse impact on organizations or individuals if released for reuse or disposal. Sanitization of non-digital media includes destruction, removing a classified appendix from an otherwise unclassified document, or redacting selected sections or words from a document by obscuring the redacted sections or words in a manner equivalent in effectiveness to removing them from the document. NSA standards and policies control the sanitization process for media that contains classified information. NARA policies control the sanitization process for controlled unclassified information.

Media Use (mp-7)

Restrict,Prohibit the use of organization-defined types of system media on organization-defined systems or system components using organization-defined controls; and

Prohibit the use of portable storage devices in organizational systems when such devices have no identifiable owner.

System media includes both digital and non-digital media. Digital media includes diskettes, magnetic tapes, flash drives, compact discs, digital versatile discs, and removable hard disk drives. Non-digital media includes paper and microfilm. Media use protections also apply to mobile devices with information storage capabilities. In contrast to #mp-2(#mp-2), which restricts user access to media, MP-7 restricts the use of certain types of media on systems, for example, restricting or prohibiting the use of flash drives or external hard disk drives. Organizations use technical and nontechnical controls to restrict the use of system media. Organizations may restrict the use of portable storage devices, for example, by using physical cages on workstations to prohibit access to certain external ports or disabling or removing the ability to insert, read, or write to such devices. Organizations may also limit the use of portable storage devices to only approved devices, including devices provided by the organization, devices provided by other approved organizations, and devices that are not personally owned. Finally, organizations may restrict the use of portable storage devices based on the type of device, such as by prohibiting the use of writeable, portable storage devices and implementing this restriction by disabling or removing the capability to write to such devices. Requiring identifiable owners for storage devices reduces the risk of using such devices by allowing organizations to assign responsibility for addressing known vulnerabilities in the devices.
