Control Statement

The organization:

  1. Sanitizes [Assignment: organization-defined information system media] prior to disposal, release out of organizational control, or release for reuse using [Assignment: organization-defined sanitization techniques and procedures] in accordance with applicable federal and organizational standards and policies; and
  2. Employs sanitization mechanisms with the strength and integrity commensurate with the security category or classification of the information.

Supplemental Guidance

This control applies to all information system media, both digital and non-digital, subject to disposal or reuse, whether or not the media is considered removable. Examples include media found in scanners, copiers, printers, notebook computers, workstations, network components, and mobile devices. The sanitization process removes information from the media such that the information cannot be retrieved or reconstructed. Sanitization techniques, including clearing, purging, cryptographic erase, 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 containing information deemed to be in the public domain or publicly releasable, or deemed to have no adverse impact on organizations or individuals if released for reuse or disposal. Sanitization of non-digital media includes, for example, removing a classified appendix from an otherwise unclassified document, or redacting selected sections or words from a document by obscuring the redacted sections/words in a manner equivalent in effectiveness to removing them from the document. NSA standards and policies control the sanitization process for media containing classified information.

Control Enhancements

MP-6(2): Equipment Testing


  • High

The organization tests sanitization equipment and procedures [Assignment: organization-defined frequency] to verify that the intended sanitization is being achieved.

MP-6(3): Nondestructive Techniques


  • High

The organization applies nondestructive sanitization techniques to portable storage devices prior to connecting such devices to the information system under the following circumstances: [Assignment: organization-defined circumstances requiring sanitization of portable storage devices].

MP-6(7): Dual Authorization


(Not part of any baseline)

The organization enforces dual authorization for the sanitization of [Assignment: organization-defined information system media].

MP-6(8): Remote Purging / Wiping Of Information


(Not part of any baseline)

The organization provides the capability to purge/wipe information from [Assignment: organization-defined information systems, system components, or devices] either remotely or under the following conditions: [Assignment: organization-defined conditions].
