Does this skill support both Istio and Linkerd?

Yes, it includes specific configurations for Istio's PeerAuthentication and DestinationRules, as well as Linkerd's automatic mTLS and server policies.

Can I use this for multi-cluster communication?

Yes, it covers certificate hierarchy concepts, including Root and Intermediate CAs, specifically designed to facilitate secure cross-cluster communication.

What is the primary benefit of using this mTLS skill?

It provides standardized, production-ready templates and debugging workflows to implement zero-trust networking, ensuring all internal service traffic is authenticated and encrypted.

How does it handle certificate rotation?

The skill provides integration patterns for Cert-Manager and SPIFFE/SPIRE to automate the issuance and rotation of short-lived workload certificates, reducing manual overhead and security risks.

How do I troubleshoot mTLS connection errors?

The skill includes specific CLI commands for checking certificate expiry, verifying peer authentication status, and debugging TLS handshakes via proxy logs.

クラウドインフラストラクチャ

Configures and manages mutual TLS (mTLS) for secure, zero-trust service-to-service communication in cloud-native architectures.

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.
