Can I use this for multi-tenant clusters?

Yes, the skill includes patterns for namespace isolation, default-deny network policies, and restricted RBAC specifically designed for multi-tenant environments.

Does it replace PodSecurityPolicy?

Since PodSecurityPolicy is deprecated, this skill focuses on the modern Kubernetes replacement: Pod Security Standards (Privileged, Baseline, and Restricted) applied via namespace labels.

Does it support service mesh security?

Yes, it includes configurations for Istio PeerAuthentication (mTLS) and AuthorizationPolicies to secure service-to-service communication.

How does this skill help with Kubernetes compliance?

It provides templates and patterns aligned with the CIS Kubernetes Benchmark and NIST frameworks, covering node authentication, audit logging, and secrets encryption.

Security & Testing

Implements production-grade Kubernetes security using NetworkPolicies, Pod Security Standards, and RBAC to secure clusters and enforce compliance.

This skill provides a comprehensive toolkit for securing Kubernetes environments through defense-in-depth strategies. It enables Claude to generate and audit security-focused manifests, including namespace-level Pod Security Standards (Privileged, Baseline, Restricted), granular NetworkPolicies for traffic isolation, and least-privilege RBAC configurations. Additionally, it supports advanced security patterns like OPA Gatekeeper constraints and Istio service mesh authentication, ensuring clusters remain compliant with industry frameworks such as the CIS Benchmarks and NIST standards.

Key Features

01Automated generation of NetworkPolicies for fine-grained ingress and egress control

02Least-privilege RBAC role and binding configuration for users and service accounts

0381 GitHub stars

04Hardened container security context configurations including non-root and read-only filesystems

05Implementation of Kubernetes Pod Security Standards (PSS) at the namespace level

06OPA Gatekeeper and Kyverno policy enforcement templates for admission control

Use Cases

01Configuring multi-tenant environments with strict access controls and resource isolation

02Hardening production clusters to meet CIS Kubernetes Benchmark and regulatory compliance

03Isolating microservices within a shared cluster to prevent lateral movement and unauthorized access
