What it checks
A Copilot Studio agent with user-authentication type 'None' accepts anonymous interaction; an agent that authenticates only 'As Needed' leaves authentication optional. Either lets unauthenticated users reach an agent that can surface organizational data or invoke tools, enabling abuse, data exfiltration, and prompt-injection. This check FAILs agents with no authentication and WARNs agents whose authentication is only triggered as-needed.
Recommended value
Every published agent requires authentication (user-authentication type is not 'None' and authentication is always enforced, not 'As Needed')
Remediation
In Copilot Studio, set each agent's authentication to require sign-in (Microsoft Entra ID authentication) rather than 'No authentication', and ensure authentication is always enforced rather than triggered only as needed. Re-publish after the change.
Fixture-proven verdicts
Every verdict below is proven by a golden fixture in the module's gating test suite. This table derives from the last green run; it cannot be edited by hand.
| Scenario | Expected verdict |
|---|---|
| clean | PASS |
| noauth | FAIL |
| not-assessed | Not Assessed |
| optional | WARN |
