What is the K8s Security Policies skill?

It is a specialized capability for Claude Code that helps developers implement and audit best-practice security configurations for Kubernetes clusters.

Does it support network isolation?

Yes, it includes templates for Default Deny policies, frontend-to-backend isolation, and specific egress rules for DNS and external services.

Can it help with compliance benchmarks?

Yes, the skill includes patterns aligned with the CIS Kubernetes Benchmark and NIST Cybersecurity Framework for auditing and enforcement.

Does it work with Istio or OPA?

Yes, it provides configuration patterns for Istio PeerAuthentication and AuthorizationPolicies, as well as OPA Gatekeeper ConstraintTemplates.

How does it handle RBAC?

It generates namespace-scoped Roles and cluster-wide ClusterRoles following the principle of least privilege, including RoleBindings and ServiceAccount configurations.

Deployment & DevOps

Implements production-grade Kubernetes security configurations including NetworkPolicy, RBAC, and Pod Security Standards.

The Kubernetes Security Policies skill provides a comprehensive framework for securing Kubernetes clusters by implementing defense-in-depth strategies. It enables Claude to generate and audit security configurations such as fine-grained RBAC roles, network isolation through NetworkPolicies, and strict Pod Security Standards. Whether you are migrating to production, implementing multi-tenancy, or ensuring compliance with CIS benchmarks, this skill offers templates and best practices for admission control via OPA Gatekeeper, service mesh security with Istio, and secure container runtime contexts.

Key Features

01Automated generation of NetworkPolicies for network segmentation

02Configuration of least-privilege RBAC roles and bindings

03Implementation of Pod Security Standards (Baseline, Restricted, Privileged)

04Setup of admission control policies using OPA Gatekeeper
