SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes resources (resource) and templates (resource) and scripts (resource) components.

What problem does it solve?

Zero-trust security standards guide the design and implementation of a zero-trust architecture with mTLS, workload identity, and continuous verification.

Core Features & Use Cases

  • mTLS & Service Mesh: Strict mutual TLS and workload identity (SPIFFE/SPIRE).
  • Policy & Segmentation: Dynamic access control with microsegmentation and zero-trust policies.
  • BeyondCorp & Verification: Identity-aware access and continuous verification patterns.

Quick Start

Enable mTLS in a service mesh, configure workload identities, and apply a default-deny policy with explicit allowances.

FAQPage Schema
How do I implement zero-trust security in Kubernetes with mTLS?▼

Zero-trust security in Kubernetes enforces mutual TLS between services using a service mesh (Istio or Linkerd) paired with SPIFFE/SPIRE workload identities. This Skill configures mTLS encryption, continuous identity verification, and default-deny network policies to ensure every service authenticates before communication, eliminating implicit trust.

What's the difference between zero-trust and traditional network security?▼

Traditional security trusts the network perimeter; zero-trust verifies every request, regardless of source. This approach applies continuous verification, workload identity, and microsegmentation across microservices rather than relying on firewall boundaries, meeting NIST SP 800-207 standards for modern cloud-native deployments.

Can I use zero-trust policies with service meshes like Istio or Linkerd?▼

Yes. This Skill integrates service meshes with SPIFFE/SPIRE workload identities and Kubernetes network policies to enforce mTLS, dynamic access control, and microsegmentation. Both Istio and Linkerd support the identity and policy mechanisms required for comprehensive zero-trust architecture.

How do I set up workload identity and access control for microservices?▼

Configure SPIFFE/SPIRE to issue cryptographic identities to each workload, then define zero-trust policies that explicitly allow service-to-service communication. This Skill provides templates and scripts to automate identity binding, mTLS enablement, and default-deny policy enforcement across your service mesh.

What are the prerequisites for deploying zero-trust architecture?▼

You need a Kubernetes cluster, a service mesh (Istio or Linkerd), SPIFFE/SPIRE for workload identity, and Kubernetes network policy support. This Skill assumes existing microservices; it layers identity, mTLS, and policy controls on top of your deployment foundation.

Does zero-trust security work for distributed microservices at scale?▼

Yes. Zero-trust with service mesh, workload identity, and continuous verification scales to large microservice deployments by automating policy enforcement and identity management. This approach handles dynamic scaling and service discovery while maintaining strict security posture across thousands of workloads.
