Kiến Trúc Bảo Mật Zero-Trust Cho Microservices: mTLS, SPIFFE/SPIRE & Identity Control
Zero-Trust Architecture for Microservices: mTLS & Production Go Guide Answer-First: Zero-Trust Architecture (ZTA) for microservices eliminates implicit internal network trust through continuous identity verification. By coupling Workload Identity (mTLS via SPIFFE/SPIRE short-lived X.509 certificates) with User Identity (OAuth 2.1 JWT token propagation), ZTA secures distributed systems against lateral attacker movement with under 2ms of cryptographic latency overhead. As a systems engineer building high-concurrency systems in Golang, I have observed traditional internal network designs relying entirely on perimeter defenses such as VPNs or static firewalls. In cloud-native microservice environments, this perimeter model presents critical security vulnerabilities. Once an attacker breaches any single internal microservice, implicit trust between internal nodes exposes the entire service mesh to lateral movement. ...
