SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires networkpolicy, rbac, podsecuritypolicy, admissioncontrol, servicemesh, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the security concerns of Kubernetes clusters, providing solutions for implementing network policies, configuring RBAC, and adhering to pod security standards.

Core Features & Use Cases

  • Kubernetes Security Policies: Offers a comprehensive guide for implementing network policies, pod security standards, RBAC, and admission control.
  • Network Policies: Implements network segmentation with NetworkPolicy for isolation and access control.
  • RBAC Configuration: Sets up least-privilege access with RBAC.
  • Admission Control: Includes OPA Gatekeeper and Kyverno policies for validation and enforcement.
  • Service Mesh Security: Enforces mTLS and authorization for service mesh security.
  • Resource Quotas and Limit Ranges: Implements resource quotas and limit ranges for resource management.
  • Compliance Frameworks: Covers CIS Kubernetes Benchmark Controls and NIST Cybersecurity Framework.
  • Best Practices: Lists security best practices and troubleshooting steps.
  • Use Case: For instance, to secure a Kubernetes cluster, this Skill can be used to enforce Pod Security Standards, configure RBAC, and implement network policies.

Quick Start

Use the k8s-security skill to enforce restricted pod security standards in the 'restricted-ns' namespace.

Frequently Asked Questions about k8s-security

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure Kubernetes RBAC for least-privilege access in production?▼

Kubernetes RBAC for least-privilege access is configured by defining Roles and RoleBindings that restrict permissions strictly to required actions. This secures production environments by preventing unauthorized resource access.

What is the best way to implement network policies for pod isolation in Kubernetes?▼

Network policies for pod isolation are implemented using NetworkPolicy resources to segment traffic and control access. This mechanism enforces strict network boundaries, preventing unauthorized inter-pod communication within clusters.

How does admission control enforce pod security standards in Kubernetes?▼

Admission control enforces pod security standards by intercepting API requests and validating them against policies using tools like OPA Gatekeeper or Kyverno. This process blocks non-compliant pod deployments before execution.

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

You can use OPA Gatekeeper and Kyverno for Kubernetes admission control to validate and enforce cluster policies. Both tools offer distinct policy-as-code frameworks to ensure resource compliance before deployment.

Do I need a service mesh to enforce mTLS and authorization in Kubernetes?▼

A service mesh is needed to enforce mTLS and authorization in Kubernetes, providing automated mutual TLS encryption and fine-grained traffic authorization. This secures service-to-service communication without modifying application code.

What compliance frameworks are supported for Kubernetes security best practices?▼

Supported compliance frameworks for Kubernetes security include CIS Kubernetes Benchmark Controls and the NIST Cybersecurity Framework. These frameworks provide structured guidelines to audit and harden cluster configurations systematically.
