_Control title and statement: NIST SP 800-53 Rev5 catalog (the pinned commit is in `/api` under `control_text`). The FedRAMP rules reference these controls by id only; everything below is what FedRAMP says about this id._

## Rev5 baseline membership

- certification class B (in the annual independent assessment)
- certification class C (in the annual independent assessment)
- certification class D (in the annual independent assessment)

## Key Security Indicators that reach it

- `KSI-CMT-LMC` — Logging Changes (Change Management)
  Modifications to the cloud service offering are logged and monitored.
- `KSI-CMT-RMV` — Redeploying vs Modifying (Change Management)
  Changes to machine-based information resources are executed through the redeployment of version controlled resources rather than direct modification wherever reasonable.
- `KSI-MLA-EVC` — Evaluating Configurations (Monitoring, Logging, and Auditing)
  The configuration of machine-based information resources, especially infrastructure as code, is persistently evaluated and tested.
- `KSI-SVC-ACM` — Automating Configuration Management (Service Configuration)
  The configuration of machine-based information resources is managed using automation and persistently reviewed for drift.
