Kubernetes Security Policies

关于

Kubernetes Security Policies provides a comprehensive framework for implementing defense-in-depth security within containerized environments. It enables users to enforce network isolation through NetworkPolicies, configure standardized pod security levels, and establish robust RBAC controls to ensure least-privilege access. Beyond basic configuration, the skill offers guidance on advanced security layers like OPA Gatekeeper for admission control, Istio service mesh security, and compliance alignment with CIS Benchmarks, making it an essential tool for hardening production-grade clusters.

主要功能

• Service mesh security configuration including Istio mTLS and AuthorizationPolicies
• RBAC configuration patterns for granular namespace-scoped and cluster-wide access control
• Detailed NetworkPolicy templates for default-deny, service-to-service, and DNS traffic control
• Policy enforcement using OPA Gatekeeper ConstraintTemplates and Rego logic
• 23,139 GitHub stars
• Implementation of Pod Security Standards including Privileged, Baseline, and Restricted profiles

使用场景

• Hardening pod configurations to meet CIS Kubernetes Benchmarks and NIST compliance standards
• Configuring least-privilege access for automated service accounts and human operators
• Implementing network segmentation and isolation in multi-tenant production clusters
