Does it support third-party security tools like OPA or Istio?

Yes, the skill includes ConstraintTemplates for OPA Gatekeeper and PeerAuthentication/Authorization policies for Istio service mesh security.

Can I use this for RBAC management?

Absolutely. It includes patterns for both namespace-scoped Roles and cluster-wide ClusterRoles, along with RoleBindings to enforce least-privilege access.

What Pod Security Standards are supported by this skill?

The skill supports the three official Kubernetes standards: Privileged (unrestricted), Baseline (minimally restrictive), and Restricted (highest security), all applied via namespace-level labels.

Does this skill help with network isolation?

Yes, it provides production-ready templates for 'Default Deny All' policies, frontend-to-backend communication rules, and specific egress rules for DNS.

How does it improve container-level security?

It provides security context configurations that enforce running as a non-root user, dropping Linux capabilities, and utilizing read-only root filesystems.

Seguridad y Pruebas

Implements production-grade defense-in-depth security for Kubernetes clusters using NetworkPolicies, Pod Security Standards, and RBAC.

Acerca de

This skill provides a comprehensive framework for securing Kubernetes environments by enforcing strict access controls and network isolation. It guides developers through the implementation of Pod Security Standards (Baseline and Restricted), fine-grained RBAC configurations, and complex NetworkPolicies designed to prevent lateral movement within a cluster. Beyond core Kubernetes primitives, it incorporates advanced patterns for OPA Gatekeeper policy enforcement and Istio service mesh security, making it an essential tool for maintaining compliance, securing multi-tenant environments, and achieving the principle of least privilege.
