SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill addresses the security concerns in Kubernetes and AKS environments by providing a comprehensive checklist for hardening cluster configurations, managing secrets, and enforcing security policies.

Core Features & Use Cases

  • Cluster Hardening: Implement cluster identity, workload identity, and RBAC to secure access.
  • Pod Security: Set up pod security policies, enforce restrictions on privileged containers, and manage resource limits.
  • Network Security: Configure network policies and enforce them using Calico, Cilium, or Azure Network Policy.
  • Image Security: Use private container registries and scan images for vulnerabilities during CI/CD pipelines.
  • Use Case: For a team deploying Kubernetes workloads, use this Skill to automatically enforce a set of security policies on a new AKS cluster to protect against common security risks.

Quick Start

Run the kubernetes-security-hardening skill to generate a security-hardened configuration for your AKS cluster.

FAQPage Schema
How do I harden an AKS cluster configuration?▼

To secure AKS clusters, apply a checklist-based hardening approach covering cluster identity, workload identity, and RBAC to restrict access and protect against common security risks.

How do I enforce pod security policies to restrict privileged containers?▼

Enforce pod security by applying policies that restrict privileged containers and manage resource limits, ensuring workloads adhere to strict security boundaries within the cluster.

What is the best way to configure Kubernetes network policies using Calico or Cilium?▼

Configure Kubernetes network policies by enforcing traffic rules using Calico, Cilium, or Azure Network Policy to isolate workloads and secure internal cluster communications.

How do I scan container images for vulnerabilities during CI/CD pipelines?▼

Achieve image security by using private container registries and scanning images for vulnerabilities during CI/CD pipelines to prevent deploying compromised or vulnerable containers.

Can I use this to manage Kubernetes secrets effectively?▼

Yes, managing Kubernetes secrets effectively is a core feature that addresses security concerns by ensuring sensitive data is handled according to industry best practices for container environments.

Do I need specific security tools for cluster management and image registry?▼

Yes, enforcing these security policies requires appropriate configurations and specific security tools for cluster management and your private image registry to ensure adherence to best practices.
