What NIST SP 800-53 Rev. 5 requires

Federal agencies and the contractors and cloud providers operating systems on their behalf; widely adopted voluntarily elsewhere.

  1. 01Select a control baseline (from SP 800-53B) based on system impact level, then tailor it.
  2. 02Implement and document controls across 20 families, including access control, audit, configuration and supply chain risk (SR).
  3. 03Assess control effectiveness, using SP 800-53A procedures, before authorization to operate.
  4. 04Continuously monitor controls and update the system security and privacy plans.
  5. 05Under Release 5.2.0, verify software update integrity and test, deploy and manage patches (SA-24, SI-02(07), SI-07(12)).

Optional evidence · where Planisphere fits

Keep a record anyone can check

When your team meets a duty, Planisphere can seal the event it reports as a receipt.

01 · Your teamRecord the event

A disclosure shown, a review signed, a model change approved: the event your system reports.

02 · PlanisphereSeal it

The event becomes a sealed receipt, dated and attributed to whoever is signed in.

03 · AnyoneCheck it

Paste the receipt into Verify. No account or key.

A record supports your compliance evidence process. It is not a legal finding or a certification. Systems that call Planisphere's gate API can also hold or refuse an action before it runs.
