Policy Based Authorization
Policy Based Authorization is a security pattern in software development where access control decisions are made based on defined policies rather than hard-coded roles or permissions. It involves creating reusable authorization policies that evaluate user attributes, resource properties, and context to determine if an action is allowed. This approach centralizes authorization logic, making it more maintainable, testable, and adaptable to complex business rules.
Developers should use Policy Based Authorization when building applications with complex or dynamic access control requirements, such as multi-tenant systems, content management platforms, or enterprise software with granular permissions. It is particularly valuable for scenarios where authorization logic needs to be reused across different parts of an application or when business rules frequently change, as it decouples authorization from application code and allows for easier updates without redeployment.
