  note: Only 6 of 103 published documents declare a securityScheme at all, though every ISE API requires HTTP Basic. The other
    97 describe authenticated operations with no security block.

model:
  mechanism: HTTP Basic (RFC 7617) over TLS. Credentials are Base64-encoded in the Authorization header.
  no_oauth: Cisco documents no OAuth 2.0 or API-key flow for the ISE administrative APIs. The OIDC OpenAPI in this repo configures
    OIDC identity providers INSIDE ISE for end-user authentication; it is not an auth mechanism for the API itself.
  authorization:
  - role: ERS Admin
    grants: Full CRUD on all ERS APIs (GET, POST, PUT, DELETE).
  - role: ERS Operator
    grants: Read-only (GET requests only).
  - role: Super Admin
    grants: Access to all API services.
  account_sources:
  - ISE internal users
  - Microsoft Active Directory group mapped to ERS Admin or ERS Operator
  csrf:
    supported: true
    modes:
    - Use CSRF Check for Enhanced Security
    - Disable CSRF for ERS Request
    behaviour: When enabled, the client GETs a CSRF token from ISE and replays it on subsequent requests. Sessions idle for
      more than 60 seconds are reset and issue a new CSRF token.
  tls:
    ers_supported:
    - TLS 1.1
    - TLS 1.2
    - TLS 1.3
    ers_not_supported:
    - TLS 1.0
    note: Enabling TLS 1.0 in ISE Security Settings affects EAP only and does not re-enable it for ERS.
  enablement:
    default: disabled
    note: API services are OFF by default. ERS and Open API must each be toggled on per node under Administration > System
      > Settings > API Settings. Calls made before enablement return an error, and unenabled nodes time out.
