Authentication and Authorization in Distributed Systems
Authentication and authorization are critical in distributed microservices systems to ensure secure communication. Patterns like OAuth2, OpenID Connect, and JWT enable identity verification and access control. Mutual TLS enhances security for service-to-service interactions, ensuring only authorized services communicate. Role-based access control (RBAC) further refines permissions, aligning with microservices’ decentralized nature. These mechanisms are essential for maintaining confidentiality, integrity, and compliance in distributed architectures, as highlighted in resources like Microservices Patterns PDF.
Service-to-Service Communication Security
Securing inter-service communication is vital in microservices architecture. Encryption, mutual TLS, and service identity verification ensure data privacy and integrity.
