Configuring Break-Glass Admin Access to an AI Governance Proxy When SSO Fails
Configure break-glass access as a separate, local-authentication path that is disabled by default, limited to a few emergency actions, and tested on a recurring schedule. If the path is always on, broadly scoped, or poorly monitored, it is a backdoor rather than a control.
Break-glass path at a glance
| Element | Requirement |
|---|---|
| Trigger | A declared incident or confirmed IdP outage, approved by named roles. |
| Authentication | Local account with a hardware-backed factor, independent of SSO. |
| Scope | Policy updates, agent credential revocation, and session control only. |
| Duration | Time-limited session that expires and disables the account automatically. |
| Evidence | Alerts on use and logs written to storage the proxy cannot alter. |
Why an IdP outage becomes a control plane outage
When administrative sign-in to the AI governance proxy depends on SSO, a failed identity provider (IdP) can leave administrators without a way to sign in. Break-glass access is a separate, local-authentication path that restores control during that outage, while limiting scope, duration, and audit risk.
Design decisions to make before you configure anything
Settle each of the following before the path is configured, because each one keeps emergency access from becoming a standing backdoor.
- Separate local authentication. Use a local account that does not depend on SSO.
- Disabled by default. The path stays off until it is needed.
- Dual-control custody. Credentials are held under dual control, and activation is approved by named roles after a declared incident or confirmed IdP outage.
- Independent MFA. Use hardware-backed MFA that does not depend on the failed identity provider.
- Limited actions. Allow only policy updates, agent credential revocation, and session control.
- Time-bound activation. The session expires and the account is disabled automatically.
- External logging. Write logs to storage outside the proxy.
- Rotation after every use. Rotate the credentials each time the path is used.
- Recurring testing. Test the path on a recurring schedule.
Logging, alerting, and keeping policy enforcement intact
Use of the break-glass account should raise an alert, and its activity should be logged to storage the proxy cannot alter. Because the account is limited to policy updates, agent credential revocation, and session control, administrators can restore control during the outage without a broader administrative surface.
Controlled emergency access versus an unmanaged backdoor
If the path is always on, broadly scoped, or poorly monitored, it is a backdoor rather than a control.
| Property | Controlled break-glass | Unmanaged backdoor |
|---|---|---|
| Availability | Disabled by default; time-limited session that expires automatically. | Always on. |
| Scope | Policy updates, agent credential revocation, and session control only. | Broadly scoped. |
| Monitoring | Alerts on use; logs written to storage the proxy cannot alter. | Poorly monitored. |
Testing, rotation, and recurring validation
Rotate the credentials after every use, and test the path on a recurring schedule so that it works when the identity provider fails. Each test should confirm the same properties described above: the account is disabled by default, the session expires and disables the account, use raises an alert, and logs reach storage outside the proxy.
