Every control family in NIST SP 800-53 Rev 5 starts with a policy and procedures control. For media protection it is MP-1. It does not say how to protect a USB drive. It says you must have written down how you do, who owns that, and that you keep it current.
800-53 binds US federal systems and, through contracts, some of their suppliers. For a small or mid size company it is a reference. An auditor or a customer reviewing your program will still ask for the policy, because it is the first document that proves the rest was intentional.
What the control asks
You develop, document and disseminate a media protection policy to people or roles you choose. The policy covers purpose, scope, roles, responsibilities, management commitment, coordination among organizational entities and compliance. It must be consistent with applicable laws, directives, regulations and standards.
You also write procedures that help carry out the policy and its controls. You designate an official to manage the policy and procedures. And you review and update both, on a schedule you set and after events you define.
The values in angle brackets in the source text are organization defined. The control does not tell you how often. You decide, then follow what you decided.
What it means in practice
Media here means both digital and non digital: flash drives, external disks, tapes, optical discs, paper and microfilm, per the MP family guidance. The policy should say what media you have, who may use it, how it is marked, stored, moved and destroyed. It should point to the matching procedures for MP-2 through MP-8.
The guidance asks security and privacy programs to work together on it. That matters if you hold personal data on paper or removable disks.
A one page policy that names a real owner and a real review date beats a forty page template nobody has read.
Evidence to collect
- The signed or approved media protection policy with version and date.
- The procedures that implement it (checkout, transport, sanitization, destruction).
- The name and role of the designated official.
- Proof of dissemination: acknowledgement records, intranet publication, onboarding checklist.
- Review history showing the last review and any change log.
- Records of policy updates after an event, such as an incident or a new regulation.
Common gaps
The policy was copied from a template and names roles you do not have. The review date passed a year ago. The policy exists but procedures do not, so the staff have no steps to follow. Dissemination is claimed but there is no record that anyone received it.
Another gap is scope. The policy mentions laptops but not paper, backup tapes or printers with hard drives.
How to implement it
Start by writing what you really do. If backups go to an external drive stored in a safe, say so. Then fix what you do not like and update the text.
Decide the review interval and write it in. Annual is common. Add trigger events too: a new office, a lost device, a changed regulation.
Name the owner by role, so the control survives staff changes. Publish the policy where employees look, and record acknowledgements. Link each procedure back to the policy section that requires it.
If you need to show this policy against more than one framework, map it once and reuse it. Mappings from MP-1 to other frameworks vary by source, so check the mapping your customer cites. The demo below walks through how a single control can map across frameworks.

Quick check
Does MP-1 tell me how often to review the policy?
No. You choose the review frequency and the events that trigger an update, then you follow it.
Is paper covered?
Yes. The media protection family covers digital and non digital media, including paper and microfilm.
Who must own the policy?
An official you designate. Naming a role rather than a person keeps the answer valid when staff change.
