Maps to 2 controls in 2 other frameworks
| Framework | Control |

| NIST Cybersecurity Framework (1.1, legacy) | PR.AC-7 Users, devices, and assets authenticated |
Mappings are CMDash’s own, seeded with the product and shown on both frameworks they connect. In the product they mean evidence you attach here also counts against the controls listed above.
In CMDash this control is a row with an owner, a status, uploaded evidence kept with its full history, and an export an assessor can read.
