Secure Microservices Architecture Questions

Focuses on practical security architecture patterns for microservices and distributed service meshes. Core areas include service identity and authentication, mutual TLS, service meshes and sidecar proxies, API gateway enforcement, zero trust principles, least privilege for service accounts, network segmentation and isolation, secure deployment pipelines, runtime protection, and observability for security. Candidates should be able to design patterns for secure service-to-service communication, identity and policy management, and discuss performance and operational trade offs.
