SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the critical need to secure Kubernetes environments by providing guidance and configurations for essential security measures like network policies, RBAC, and pod security standards.

Core Features & Use Cases

  • Pod Security Standards: Implement restricted and secure pod configurations.
  • Network Policies: Define rules for ingress and egress traffic, including default deny and specific allow rules.
  • RBAC Configuration: Set up roles and role bindings for granular access control.
  • OPA Gatekeeper: Integrate custom policies for enhanced security governance.
  • Service Mesh Security: Configure strict mTLS for communication within service meshes like Istio.
  • Use Case: A DevOps engineer needs to ensure that only authorized services can communicate within the cluster and that pods adhere to security best practices. This Skill provides the necessary YAML configurations and commands to achieve this.

Quick Start

Apply the 'default-deny-all' NetworkPolicy to restrict all ingress and egress traffic within the cluster.

Frequently Asked Questions about k8s-security

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

FAQPage Schema
How do I secure Kubernetes pods using Pod Security Standards?▼

Secure Kubernetes pods by applying Pod Security Standards to enforce restricted configurations. This Skill provides YAML definitions to implement baseline or restricted policies, ensuring your deployments adhere to defense-in-depth security principles without manual validation overhead.

What is the best way to restrict ingress and egress traffic in Kubernetes?▼

Restrict ingress and egress traffic in Kubernetes by applying a default-deny-all Network Policy. This Skill provides the configurations needed to segment cluster communication, allowing only explicitly authorized service routes to prevent lateral movement.

How do I configure RBAC for least-privilege access control in Kubernetes?▼

Configure RBAC for least-privilege access by defining specific Roles and RoleBindings. This Skill offers the necessary YAML configurations to set up granular permissions, ensuring service accounts and users only interact with authorized API objects.

Does this Skill support integrating OPA Gatekeeper for custom cluster policies?▼

Yes, this Skill supports OPA Gatekeeper integration to enforce custom security governance policies. It provides configurations that allow you to define and apply constraint templates, extending native Kubernetes admission control for enhanced compliance validation.

Can I use this to configure strict mTLS within an Istio service mesh?▼

Yes, you can configure strict mTLS within an Istio service mesh using this Skill. It delivers the required configurations to enforce encrypted communication between services, ensuring traffic segmentation and securing internal service mesh interactions.

Do I need prior knowledge of Kubernetes API objects to use these security configurations?▼

Yes, understanding Kubernetes API objects and security principles is required. This Skill provides the YAML configurations and commands for RBAC, network policies, and pod security, but expects foundational DevOps or administration experience to apply effectively.
