mTLS Configuration & Zero Trust Networking

About

This skill provides a comprehensive framework for implementing zero-trust networking through mutual TLS (mTLS). It guides developers through certificate hierarchy design, automated rotation, and policy enforcement using industry-standard tools like Istio, Linkerd, and SPIFFE/SPIRE. Whether migrating from legacy setups using permissive modes or enforcing strict security in production, this skill simplifies complex networking configurations to ensure robust, encrypted internal communication that meets high-compliance standards like PCI-DSS and HIPAA.

Key Features

• Standardized patterns for multi-cluster secure service communication
• Strict and Permissive mTLS policy templates for Istio and Linkerd
• 1 GitHub stars
• Short-lived workload certificate rotation and CA hierarchy best practices
• Automated certificate management via Cert-Manager and SPIRE integration
• Comprehensive debugging workflows for resolving TLS handshake failures

Use Cases

• Securing microservices communication within a Kubernetes-based service mesh
• Implementing zero-trust architecture to meet industry compliance requirements
• Managing automated certificate lifecycles across distributed cloud environments
