What are Kubernetes Pod Security Standards?

They are predefined security profiles—Privileged, Baseline, and Restricted—used to control the security level of pods running in specific namespaces.

How does this skill assist with network isolation?

It provides ready-to-use NetworkPolicy templates for default-deny-all, frontend-to-backend communication, and DNS egress to prevent lateral movement.

Does it support third-party security tools?

The skill includes specific configurations for OPA Gatekeeper for admission control and Istio for service mesh security (mTLS).

Can I use this skill for RBAC management?

Yes, it includes patterns for Role, ClusterRole, and RoleBindings to help you implement the principle of least privilege for both users and service accounts.

Deployment & DevOps

Implements production-grade Kubernetes security using NetworkPolicies, Pod Security Standards, and RBAC configurations.

About

This skill provides a comprehensive framework for securing Kubernetes clusters by applying defense-in-depth principles. It enables developers and DevOps engineers to implement granular network segmentation, enforce pod security standards, and configure least-privilege RBAC for users and service accounts. Beyond basic configurations, it includes advanced patterns for OPA Gatekeeper admission control and Istio service mesh security, ensuring clusters meet strict compliance frameworks like CIS Benchmarks and NIST standards.

Key Features

Service mesh security hardening with Istio mTLS and AuthorizationPolicies
Standardized implementation of Pod Security Standards (Privileged, Baseline, Restricted)
Least-privilege RBAC configuration for namespaces and cluster-wide resources
3 GitHub stars
Granular network isolation using ingress and egress NetworkPolicies
Policy enforcement patterns using OPA Gatekeeper and ConstraintTemplates

Use Cases

Enforcing security guardrails and admission control via infrastructure as code
Automating compliance with CIS Kubernetes Benchmarks and NIST frameworks
Hardening production Kubernetes clusters for multi-tenant isolation
