Is it compatible with service meshes like Istio?

Absolutely, it provides patterns for PeerAuthentication (mTLS) and AuthorizationPolicies to secure inter-service communication within the mesh.

Can I use this for multi-tenant cluster isolation?

Yes, it includes specific configurations for default-deny NetworkPolicies and namespace-scoped Pod Security Standards to ensure strict tenant isolation.

How does this skill help with Kubernetes compliance?

It provides templates and patterns that align with the CIS Kubernetes Benchmark and NIST frameworks, including RBAC auditing and network segmentation.

Does it support admission controllers like OPA Gatekeeper?

Yes, the skill includes ConstraintTemplates and Constraints for OPA Gatekeeper to enforce custom security policies at the admission control level.

Seguridad y Pruebas

Implements defense-in-depth security for Kubernetes clusters through network isolation, RBAC, and pod security standards.

Acerca de

This skill provides a comprehensive toolkit for securing Kubernetes clusters by automating the creation of NetworkPolicies, Role-Based Access Control (RBAC) configurations, and Pod Security Standards. It enables users to implement granular network segmentation, configure least-privilege access, and enforce runtime security constraints using OPA Gatekeeper and Istio. Designed for production-grade environments, it simplifies the complex task of aligning clusters with CIS benchmarks and NIST frameworks while ensuring secure multi-tenant isolation and automated policy enforcement.

Características Principales

Namespace-level enforcement of Pod Security Standards (Privileged, Baseline, Restricted)
Automated generation of default-deny and application-specific NetworkPolicies
Service mesh security configuration including mTLS and AuthorizationPolicies
Integration with OPA Gatekeeper for custom policy admission control
Least-privilege RBAC configuration for users and service accounts
1 GitHub stars

Casos de Uso

Implementing zero-trust architecture within a service mesh using Istio policies
Securing multi-tenant clusters through network isolation and namespace-level restrictions
Hardening production workloads to meet CIS Kubernetes Benchmark requirements
