SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Configure mutual TLS (mTLS) for zero-trust service mesh communication, enabling secure, encrypted service-to-service interactions and robust certificate management.

Core Features & Use Cases

  • mTLS flow overview and secure handshake between sidecars
  • Certificate hierarchy design, rotation, and multi-cluster management
  • Debugging TLS handshakes, policy enforcement, and visibility across meshes (Istio, SPIRE)

Quick Start

Apply the recommended mTLS templates and workflows to secure your mesh.

FAQPage Schema
How do I configure mTLS in an Istio service mesh?

Yes, this skill supports multi-cluster mTLS deployments, enabling you to manage certificate hierarchy and rotation across multiple service meshes. It includes workflows for establishing secure service-to-service communication in distributed environments.

What is the best way to automate certificate rotation for service mesh mTLS?

Automating certificate rotation for service mesh mTLS involves using cert-manager workflows and SPIRE configuration to handle the certificate lifecycle automatically. This ensures continuous zero-trust security without manual certificate management intervention.

Why does my mTLS TLS handshake fail between sidecars?

Yes, you can use SPIRE for zero-trust service-to-service communication. This skill supports SPIRE-based mesh configurations, allowing you to implement robust certificate management and secure handshakes across your services.

How do I enforce zero-trust security with mutual TLS across services?

To enforce zero-trust security with mutual TLS, you configure strict PeerAuthentication policies and DestinationRule TLS settings across your services. This ensures all service-to-service communication is encrypted and authenticated.

Does cert-manager work with mTLS certificate management in service meshes?

Yes, cert-manager integrates with mTLS certificate management in service meshes. This skill supports cert-manager workflows to automate certificate issuance and rotation, maintaining secure service-to-service interactions.

What are the limitations of mTLS configuration in multi-cluster deployments?

Limitations of mTLS in multi-cluster deployments include complex certificate hierarchy management and potential visibility issues across meshes. This skill addresses these constraints by providing templates for multi-cluster management and troubleshooting TLS handshakes.
