Does it integrate with service meshes?

Yes, it includes support for Istio PeerAuthentication to enforce mTLS and AuthorizationPolicies to control service-to-service communication.

Can it help troubleshoot RBAC permission issues?

Yes, it includes specialized commands and debugging patterns for verifying effective permissions and identifying missing roles or bindings.

Does this skill support the latest Pod Security Standards?

Yes, it includes configurations for Privileged, Baseline, and Restricted standards, providing a modern replacement for deprecated PodSecurityPolicies.

Can I use this for multi-tenant cluster isolation?

Absolutely. It provides templates for default-deny NetworkPolicies and namespace-scoped RBAC specifically designed for multi-tenant environments.

How does it help with compliance?

The skill automates the implementation of technical security controls required by major frameworks like the CIS Kubernetes Benchmark and NIST Cybersecurity Framework.

Security & Testing

Implements production-grade Kubernetes security through NetworkPolicies, Pod Security Standards, and robust RBAC configurations.

About

This skill provides a comprehensive toolkit for securing Kubernetes clusters by enforcing defense-in-depth strategies. It enables Claude to generate and configure sophisticated NetworkPolicies for traffic isolation, implement modern Pod Security Standards (Privileged, Baseline, and Restricted), and manage least-privilege RBAC roles for users and service accounts. Beyond basic manifests, it supports advanced security patterns such as OPA Gatekeeper constraints for admission control and Istio-based service mesh security, making it an essential resource for developers building compliant, multi-tenant, and hardened cloud-native environments.

Key Features

Automated NetworkPolicy generation for ingress and egress traffic isolation
Least-privilege RBAC configuration for users, roles, and service accounts
Service mesh security configuration including mTLS and AuthorizationPolicies
Implementation of Kubernetes Pod Security Standards (PSS) at the namespace level
Admission control enforcement using OPA Gatekeeper ConstraintTemplates
23,194 GitHub stars

Use Cases

Hardening container workloads for CIS Kubernetes Benchmark or NIST compliance
Automating the enforcement of security contexts like non-root execution and read-only filesystems
Securing multi-tenant Kubernetes clusters with namespace-level network and resource isolation
