Independent summary of the official requirement

Develop, document, and disseminate to designated personnel or roles the policies and procedures needed to satisfy the security requirements for protecting CUI, and review and update them at organization-defined frequencies.

Rev. 3 requirement text is multi-part and parameterized with organization-defined values, so this site summarizes rather than reproduces it. The summary is independent — read the official publication for the binding wording.

Independent interpretation

What this requirement is after

Rev. 2 assumed policies existed; Rev. 3 asks for them. Every family in this catalog now expects a written statement of what the organization requires and a procedure for how it happens, reviewed on a cadence — because implementations drift, and an implementation nobody wrote down cannot be handed to the next person or checked by anyone.

Across revisions

New as a standalone requirement — Rev. 2 contained no explicit policy requirement, leaving governance documentation implied. Rev. 3 makes it assessable in its own right.

Doing the work

Implementation considerations and evidence

Implementation considerationsIndependent guidance — tailor to your environment
  • One policy set following the catalog's family structure is easier to maintain and assess than dozens of freestanding documents; procedures belong closest to the teams that execute them.
  • Write policy to match what the organization actually does — an aspirational policy that operations contradicts reads worse in an assessment than a modest one that is true.
  • Set the review frequency, put it on a calendar, and name an owner; the review-and-update half of this requirement is the part that silently lapses.
What operating evidence looks likeRecords worth retaining, not a submission checklist
  • The policy and procedure set with version history and dissemination records
  • Dated review records showing the defined frequency is honored

Suggested owners, derived from the mapped practices and artifacts: IT leader. Ownership is a named person in your organization, not a role on a website.
