Cedar Policy Language
Cedar is an open-source policy language designed for defining and enforcing authorization policies in cloud applications and services. It provides a declarative, human-readable syntax for specifying fine-grained access control rules, such as who can perform what actions on which resources. Developed by AWS, it is used in services like AWS Verified Permissions and Amazon Verified Access to manage permissions securely and scalably.
Developers should learn Cedar when building or integrating authorization systems in cloud environments, especially for applications requiring complex, attribute-based access control (ABAC) or role-based access control (RBAC). It is particularly useful in scenarios like multi-tenant SaaS applications, enterprise security tools, or any system where fine-grained permissions must be defined and audited independently from application code, as it decouples policy logic for easier management and compliance.
