Application require authorization decisions made at the API gateway, frontend, backend, and database. OPA helps developers decouple authorization logic from application code, define a custom authorization model that enables end-users to control tenant permissions, and enforce that policy across the different components of the application (gateway, frontend, backend, database).

Kubernetes Authorization

Kubernetes Authorization is a pluggable mechanism that lets administrators control which users can run which APIs and is often handled by builtin RBAC. OPA's policy language is more flexible than the RBAC, for example, writing policy using a prohibited list of APIs instead of the usual RBAC style of listing the permitted APIs.

OPAL (Open Policy Administration Layer)

OPAL is an administration layer for Open Policy Agent (OPA), detecting changes in realtime to both policy and policy data and pushing live updates to your agents. OPAL brings open-policy up to the speed needed by live applications. As your application state changes (whether it's via your APIs, DBs, git, S3 or 3rd-party SaaS services), OPAL will make sure your services are always in sync with the authorization data and policy they need (and only those they need).

Magda

Magda is a federated, Kubernetes-based, open-source data catalog system. Working as Magda's central authorisation policy engine, OPA helps not only the API endpoint authorisation. Magda also uses its partial evaluation feature to translate datasets authorisation decisions to other database-specific DSLs (e.g. SQL or Elasticsearch DSL) and use them for dataset authorisation enforcement in different databases.
