SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the critical risk of misconfigured Kubernetes network environments, such as overly permissive access, accidental public exposure, and lack of encryption, which can lead to data breaches and lateral movement.

Core Features & Use Cases

Network Isolation Audit: Validates the presence of default-deny policies and identifies overly broad CIDR ranges.
Exposure Detection: Flags services that are accidentally exposed to the public internet or use insecure protocols.
Traffic & Mesh Security: Ensures mTLS enforcement and validates Ingress TLS configurations to maintain a zero-trust architecture.

Quick Start

Use the review-security-k8s-network skill to perform a comprehensive security audit of all network policies and service configurations in the current cluster.

FAQPage Schema

How do I audit Kubernetes NetworkPolicies to find isolation gaps?▼

To audit Kubernetes network security, you analyze NetworkPolicies, Services, and Ingress resources to validate default-deny enforcement, detect overly broad CIDR ranges, and identify isolation gaps that risk unauthorized lateral movement.

What is the best way to detect accidentally exposed Kubernetes Services?▼

Exposure detection in Kubernetes identifies services accidentally exposed to the public internet or using insecure protocols. It evaluates cluster-wide security posture by flagging public service exposure and validating Ingress TLS configurations.

Can I use this to check my GKE cluster for mTLS compliance and zero-trust architecture?▼

Yes, you can check GKE clusters for mTLS compliance by ensuring traffic mesh security enforcement and validating Ingress TLS configurations. This evaluates your infrastructure against hardened networking standards to maintain a zero-trust architecture.

How do I perform a Kubernetes network security audit for data exfiltration risks?▼

Performing a Kubernetes network security audit involves analyzing network configurations to prevent unauthorized access and data exfiltration. It validates infrastructure against hardened networking standards to identify exposure risks and isolation gaps.

Why does my Kubernetes cluster lack default-deny network policy enforcement?▼

A Kubernetes cluster lacks default-deny enforcement when NetworkPolicies are absent or overly permissive. Auditing identifies these isolation gaps by checking for missing default-deny rules and evaluating broad CIDR ranges that allow unauthorized traffic.
