Mutual TLS configuration for zero-trust service mesh communication with certificate management. Comprehensive guide to implementing mutual TLS for zero-trust service mesh communication. - Covers Istio, Linkerd, cert-manager, and SPIFFE/SPIRE implementations with ready-to-use YAML templates for strict mTLS enforcement, workload policies, and external service integration - Includes certificate hierarchy design, automatic rotation strategies, and port-level mTLS control for mixed-protocol environments - Provides debugging commands for TLS handshake issues, certificate expiry verification, and peer authentication validation across service meshes - Addresses migration patterns (PERMISSIVE to STRICT modes), multi-cluster communication, and compliance requirements (PCI-DSS, HIPAA) - Implementing zero-trust networking - Securing service-to-service communication - Certificate rotation and management - Debugging TLS handshake issues - Compliance requirements (PCI-DSS, HIPAA) - Multi-cluster secure communication - Start with PERMISSIVE - Migrate gradually to STRICT - Monitor certificate expiry - Set up alerts - Use short-lived certs - 24h or less for workloads - Rotate CA periodically - Plan for CA rotation - Log TLS errors - For debugging and audit - Don't disable mTLS - For convenience in production - Don't ignore cert expiry - Automate rotation - Don't use self-signed certs - Use...
