Can this skill help with automated certificate rotation?

Yes, it includes specific workflows for monitoring certificate expiry and managing automated rotations using tools like Istio, cert-manager, and Linkerd.

What is the difference between permissive and strict mTLS mode?

Permissive mode allows both plain text and mTLS traffic, which is ideal for migration. Strict mode enforces mTLS for all connections and rejects any unencrypted traffic.

Does it support cross-cluster secure communication?

Yes, the skill provides architectural patterns for Intermediate CAs and multi-cluster certificate hierarchies to ensure secure communication between different environments.

How can I debug a failing TLS handshake using this skill?

The skill includes specialized commands for checking proxy-config secrets, verifying peer authentication policies, and extracting debug logs from sidecar proxies.

Security & Testing

Automates the setup and management of mutual TLS (mTLS) for secure, zero-trust service-to-service communication.

This skill provides a comprehensive framework for implementing zero-trust networking through mutual TLS (mTLS) across various service mesh environments like Istio and Linkerd. It enables developers to secure internal service communication, manage complex certificate hierarchies, and automate rotation while ensuring compliance with standards like PCI-DSS and HIPAA. By providing ready-to-use templates for strict authentication, destination rules, and integration with certificate managers like SPIRE and cert-manager, it significantly simplifies the implementation of identity-based security in distributed systems.
