IAM
IAM (Identity and Access Management) is a framework of policies and technologies that ensures the right individuals have appropriate access to technology resources. It manages user identities, authentication, authorization, and permissions across systems and applications. IAM is critical for security, compliance, and operational efficiency in modern IT environments.
Developers should learn IAM to implement secure access controls in applications, especially for cloud-based services, microservices architectures, and multi-tenant systems. It is essential for protecting sensitive data, meeting regulatory requirements like GDPR or HIPAA, and managing user roles in enterprise software. Use cases include single sign-on (SSO), role-based access control (RBAC), and API security.
