Can I use this for RBAC management?

Yes, it includes predefined patterns for creating Roles, ClusterRoles, and RoleBindings focused on the principle of least privilege for both users and service accounts.

Does this skill help with security compliance?

The templates and best practices provided are designed to align with the CIS Kubernetes Benchmark and NIST Cybersecurity Framework requirements for cluster hardening.

Does it support the new Pod Security Admission controller?

Yes, the skill includes namespace labeling configurations for the official Kubernetes Pod Security Admission levels: Privileged, Baseline, and Restricted.

How does this skill handle NetworkPolicies?

It provides standardized templates for default-deny-all, frontend-to-backend communication, and DNS egress rules to ensure strict network segmentation within your cluster.

Is it compatible with service meshes like Istio?

Absolutely. It includes security configurations for Istio, specifically PeerAuthentication for mTLS enforcement and AuthorizationPolicies for granular access control.

Deployment & DevOps

Implements production-grade Kubernetes security using NetworkPolicies, Pod Security Standards, and RBAC to harden cluster environments.

This skill provides a comprehensive framework for securing Kubernetes clusters by enforcing defense-in-depth strategies. It enables developers and DevOps engineers to implement sophisticated network segmentation, fine-grained access control through RBAC, and strict pod security standards to mitigate risks in multi-tenant environments. By offering templates for admission control via OPA Gatekeeper and service mesh security with Istio, it ensures that security is integrated throughout the deployment lifecycle, helping clusters meet rigorous compliance benchmarks like CIS and NIST.
