What is authorization? Examples and definitions

Authorization is a fundamental component of secure systems that controls access to resources based on rules, contextual details, and checks. Various paradigms like Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Relationship-Based Access Control (ReBAC) offer different approaches to managing permissions. Key practices include adhering to the principle of least privilege, conducting regular audits, ensuring scalability, balancing flexibility and security, and monitoring performance. Effective authorization balances ease of use with security, protecting sensitive information while remaining user-friendly.
