Huawei's GaussDB database supports both Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC) models. RBAC assigns permissions based on predefined roles, simplifying administration for static environments. ABAC, on the other hand, uses attributes (user, resource, environment) to dynamically evaluate access, offering finer granularity and flexibility. This article explores the implementation of both models in GaussDB, including practical examples of role hierarchies, attribute policies, and hybrid approaches. For database engineers and security architects, understanding these models is crucial for designing access control that balances security with operational efficiency. The content is evergreen and serves as a reference for permission management in distributed databases.
