EFA RBAC Policy Enforcement

EFA implements an RBAC (Role-based Access Control) policy governing access to northbound REST APIs.

The RBAC policy is enforced at the northbound interface, immediately after validation of the access token. An error message is returned if an RBAC permissions check fails.

RBAC and REST URI matrix

The RBAC policy is expressed in a permissions matrix indexed by RBAC role and REST URI, in which each matrix element enumerates the permitted HTTP methods.

Table 1. RBAC and REST matrix
Role A Role B Role C
REST URI 1 GET GET GET, POST, PUT, PATCH, DELETE
REST URI 2 GET, POST GET, POST, PUT GET, POST, PUT, PATCH, DELETE
REST URI 3 GET, POST GET, POST GET, POST, PUT, PATCH, DELETE

RBAC roles

Roles can be populated into the upstream LDAP instance.
