Rhino Security is an open source security framework designed to provide authorization capabilities for .NET applications. It focuses on managing users, roles, permissions, and access rules within custom software systems. The framework allows developers to define and enforce role-based and permission-based access control policies. It supports assigning users to roles, granting permissions to roles or individual users, and validating whether a user is authorized to perform a specific action. Rhino Security is intended to be integrated into application architectures rather than used as a standalone product. It provides programmatic APIs and infrastructure components that developers can use to implement security logic in line with their business requirements. The framework concentrates on authorization management and does not replace authentication systems. Instead, it complements existing identity mechanisms by enforcing access rules within application logic.
