Level 5 CMMC - CMMC Practices

MP.1.118  

Reference: CMMC 1.02

Family: MP

Level Introduced: 1

Practice:
Sanitize or destroy information system media containing Federal Contract Information before disposal or release for reuse.

CMMC Clarification:
In this case, “media” can mean something as simple as paper, or storage devices like diskettes, disks, tapes, microfiche, thumb drives, CDs and DVDs, and even mobile phones. It is important to see what information is on these types of media. If there is Federal contract information (FCI)—information you or your company got doing work for the Federal government that is not shared publicly)—you or someone in your company should do one of two things before throwing the media away:
• clean or purge the information, if you want to reuse the device; or
• shred or destroy the device so it cannot be read.
See NIST Special Publication 800-88 Revision 1, Guidelines for Media Sanitization for more information.

Example
You are moving into a new office. As you pack for the move, you find some of your old CDs in a file cabinet. When you load the CDs into your computer drive, you see that one has information about an old project your company did for the Department of Defense (DoD). Rather than throw the CD in the trash, you make sure that it is shredded.

3.8.3

Sanitize or destroy system media containing CUI before disposal or release for reuse.

Discussion:
This requirement applies to all system media, digital and non-digital, subject to disposal or reuse.
Examples include: digital media found in workstations, network components, scanners, copiers, printers, notebook computers, and mobile devices; and non-digital media such as paper and microfilm. 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 released for reuse or disposal.

Organizations determine the appropriate sanitization methods, recognizing that destruction may be necessary when other methods cannot be applied to the media requiring sanitization. Organizations use discretion on the employment of sanitization techniques and procedures for media containing information that is 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 destruction, removing CUI from documents, or redacting selected sections or words from a document by obscuring the redacted sections or words in a manner equivalent in effectiveness to removing the words or sections from the document. NARA policy and guidance control sanitization processes for controlled unclassified information.

MEDIA SANITIZATION

Description:
The organization:
    a. 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
    b. 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. Related controls: MA-2, MA-4, RA-3, SC-4.
