What is OPAL?

OPAL (Open Policy Administration Layer) is an open-source framework for building, testing, and distributing fine-grained access control policies. It helps in decoupling policy logic from application code, enabling centralized management and real-time updates of policies. OPAL uses Git for policy versioning and distribution and supports various policy languages like Rego. It's commonly used in cloud-native environments, microservices architectures, and Kubernetes to enforce consistent security policies across distributed systems.
