API Authorization
API Authorization is the process of determining what actions an authenticated user or system is permitted to perform when accessing an API. It involves enforcing access control policies to ensure that only authorized entities can access specific resources or operations. This is a critical security layer that works alongside authentication to protect APIs from unauthorized use.
Developers should learn API Authorization to secure their applications by controlling access to sensitive data and functionality, such as in microservices architectures, mobile apps, or web APIs. It's essential for implementing role-based access control (RBAC), scoped permissions, and compliance with regulations like GDPR or HIPAA, preventing data breaches and ensuring proper user segregation.
