Keycloak Query-Level Approval: Precise, Context-Aware Data Access Control

A single query can decide who gets access to your most sensitive data. Keycloak Query-Level Approval makes sure that decision isn’t left to chance.

Keycloak is a proven open-source identity and access management platform. Out of the box, it lets you enforce role-based access and fine-grained permissions. But query-level approval takes it further. It adds a deliberate checkpoint: every read or write request passes through an explicit approval logic before returning results.

With query-level approval, you can lock down not just the resource, but the exact slice of data a query can touch. Combine it with Attribute-Based Access Control (ABAC) to match permissions against context — user identity, query parameters, environment. This works across REST APIs, GraphQL endpoints, and direct database queries tied to Keycloak’s policies.

Implementing it means writing a policy that acts on dynamic query inputs. For example, a search request hitting sensitive fields will trigger an approval workflow. That workflow can require human review, automated checks, or both. Denials block the query before data leaves the system. Approvals are logged for audits, ensuring traceability.

The advantages are precise control, better compliance, and stronger security posture. This approach counters over-fetching, privilege escalation, and insider threats. Query-level approval ensures users only ever get data they are entitled to, no matter how sophisticated their requests.

To set it up in Keycloak, define a fine-grained policy, bind it to the client scope or resource, and pass the query context into the authorization service. Use Keycloak’s Admin REST API to integrate your custom approval logic. Deploy the decision engine close to the data layer for speed and reliability.

Security today demands controls at every layer. Keycloak Query-Level Approval delivers that control at the exact point where data is requested.
