How does this skill help with Kubernetes compliance?

It provides configuration templates specifically aligned with the CIS Kubernetes Benchmark and NIST frameworks, including audit logging, secrets encryption, and node authentication best practices.

Does it support Service Mesh security like Istio?

Yes, it includes specialized patterns for Istio PeerAuthentication to enforce mTLS and AuthorizationPolicies to secure inter-service communication.

Does this skill replace PodSecurityPolicies (PSP)?

Yes, it implements the modern replacement: Kubernetes Pod Security Standards (PSS), providing templates for Privileged, Baseline, and Restricted enforcement levels.

Can it generate NetworkPolicies for existing microservices?

Yes, the skill can analyze your architecture and generate specific NetworkPolicies to restrict traffic between frontend, backend, and external services based on labels.

Security & Testing

Implements robust, production-grade security controls for Kubernetes clusters including network isolation, RBAC, and pod security standards.

About

This skill empowers Claude to architect and implement defense-in-depth security strategies for Kubernetes environments by providing standardized templates and implementation patterns. It covers the full spectrum of cluster hardening, including automated NetworkPolicy generation for traffic isolation, the application of Pod Security Standards (Privileged, Baseline, and Restricted), and the configuration of least-privilege RBAC. Beyond native controls, the skill assists in deploying advanced security layers like OPA Gatekeeper for admission control and Istio for service mesh encryption, ensuring clusters meet rigorous compliance frameworks like CIS Benchmarks and NIST standards.
