How does this skill help with Kubernetes network security?

The skill provides templates and logic for implementing 'Default Deny' policies and specific ingress/egress rules to ensure microservices can only communicate with authorized endpoints.

Does it support the newer Pod Security Standards?

Yes, it includes templates for labeling namespaces with Privileged, Baseline, and Restricted enforcement levels, which replaced the deprecated PodSecurityPolicy.

Can I use this for RBAC management?

Absolutely. It provides patterns for creating namespace-scoped Roles and cluster-wide ClusterRoles, ensuring service accounts follow the principle of least privilege.

Does this skill work with OPA Gatekeeper?

Yes, it includes ConstraintTemplates and Constraints for OPA Gatekeeper to enforce custom policies like requiring specific labels or image registries.

Is it compatible with Service Meshes like Istio?

The skill includes configurations for Istio PeerAuthentication and AuthorizationPolicies to enable mTLS and fine-grained service-to-service security.

Seguridad y Pruebas

Implements production-grade Kubernetes security policies including NetworkPolicy, RBAC, and Pod Security Standards to harden cluster infrastructure.

This skill provides a comprehensive framework for implementing defense-in-depth security within Kubernetes clusters. It enables developers and DevOps engineers to quickly generate and apply essential security configurations, ranging from network isolation via NetworkPolicies to fine-grained access control using RBAC. The skill guides users through enforcing Pod Security Standards (PSS) at the namespace level, configuring secure container contexts, and implementing advanced policy enforcement with OPA Gatekeeper. It is particularly valuable for securing multi-tenant environments, preparing for compliance audits, and ensuring that all deployments follow industry best practices such as the CIS Kubernetes Benchmark.
