PermitAuthorize

Permitauthorize is a term used in software security to describe a design pattern that combines permission checks with formal authorization decisions into a unified policy-driven workflow. It emphasizes evaluating whether an action on a resource should be allowed based on policy rules and the current context, rather than relying solely on static permissions. The approach is common in modern identity and access management, API gateways, and middleware for microservices.

In practice, permitAuthorize typically involves a policy decision point (PDP) that evaluates policies using attributes of the subject, resource, action, and environment. The decision is then enforced by a policy enforcement point (PEP), which either permits or denies the request. This architecture supports both RBAC and ABAC and can incorporate contextual factors such as time, location, or resource state. Tools and standards used in permitAuthorize often include policy languages and engines similar to those used in Open Policy Agent (OPA) or XACML-based systems.

Relation to related concepts: PermitAuthorize aligns with policy-based access control (PBAC) and ABAC/RBAC approaches, providing a flexible framework for expressing access rules. It is typically implemented as part of a broader access-control stack that includes authentication, authorization, and auditing components.

Implementation considerations include performance and caching strategies, policy versioning and revocation, auditing and traceability of decisions, and governance to prevent policy sprawl. When well implemented, permitAuthorize enables centralized, auditable, and context-aware access control across services and APIs.
