SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

This Skill helps you secure Kubernetes clusters by turning broad, error-prone access into explicit network, pod, and identity controls for production environments.

Core Features & Use Cases

  • Network Isolation: Define default-deny and allowlist NetworkPolicy rules for service-to-service traffic, DNS, ingress controllers, databases, and cross-namespace access.
  • Pod Hardening: Apply Pod Security Standards and secure container settings such as non-root execution, read-only filesystems, seccomp, and dropped capabilities.
  • Least-Privilege Access: Build Roles, ClusterRoles, and RoleBindings that limit permissions for users, service accounts, and CI/CD workflows.
  • Policy Enforcement: Extend safeguards with OPA Gatekeeper and Istio authorization and mTLS policies for multi-layer cluster protection.

Quick Start

Ask the skill to generate secure Kubernetes policies for a production namespace with default-deny networking, restricted pod settings, and least-privilege RBAC.

FAQPage Schema
How do I configure Kubernetes NetworkPolicy for default-deny and namespace isolation?▼

Kubernetes NetworkPolicy default-deny rules block all ingress and egress traffic, then allowlist specific service-to-service, DNS, ingress, and cross-namespace access for multi-tenant isolation. You define explicit allow rules to secure service communication.

What Kubernetes pod security settings are needed for production hardening?▼

Pod hardening for production clusters requires applying Pod Security Standards with non-root execution, read-only filesystems, seccomp profiles, and dropped Linux capabilities to restrict container privileges and prevent escalation.

How do I set up least-privilege RBAC roles for Kubernetes service accounts?▼

Least-privilege RBAC limits permissions by creating targeted Roles and ClusterRoles bound via RoleBindings to specific users, service accounts, and CI/CD workflows, ensuring components only access the resources they explicitly need.

Can I use OPA Gatekeeper and Istio together for Kubernetes admission control?▼

OPA Gatekeeper and Istio can be combined for multi-layer cluster protection. Gatekeeper handles admission control for resource creation, while Istio enforces service mesh mTLS and authorization policies for runtime traffic security.

Does this approach work for multi-tenant Kubernetes cluster isolation?▼

Yes, multi-tenant isolation is achieved by combining namespace-level Pod Security Standards enforcement, default-deny NetworkPolicy design, and least-privilege RBAC patterning to restrict cross-tenant access and secure shared cluster environments.
