Authorization
Authorization is a security concept that determines what authenticated users or systems are allowed to access and perform within an application or system. It involves defining and enforcing access control policies, permissions, and roles to ensure users only interact with resources they're permitted to use. This is typically implemented after authentication (verifying identity) in the security workflow.
Developers should learn authorization to build secure applications that protect sensitive data and functionality from unauthorized access. It's essential for implementing role-based access control (RBAC), permission systems in multi-user applications, and compliance with security standards like GDPR or HIPAA. Common use cases include restricting admin panels to authorized personnel, controlling data visibility in SaaS platforms, and securing API endpoints in microservices architectures.
