SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the risk of misconfigured Kubernetes environments where poor namespace isolation, excessive privileges, and cross-namespace vulnerabilities expose the cluster to lateral movement and unauthorized access.

Core Features & Use Cases

Structural Isolation Audit: Detects workload density issues and improper mixing of trust levels (e.g., dev/prod) within the same namespace.
Abuse & Evasion Detection: Identifies system namespace abuse, rogue namespaces, and policy bypass attempts like OPA exemptions or privileged security contexts.
Cross-Namespace Risk Analysis: Flags dangerous resource references and dangling secrets or service accounts that increase the attack surface.

Quick Start

Use the review-security-k8s-namespaces skill to perform a comprehensive security audit of all namespaces in the current cluster context.

FAQPage Schema

How do I audit Kubernetes namespaces for security misconfigurations?▼

To audit Kubernetes namespaces for security misconfigurations, you must evaluate structural isolation, detect system namespace abuse, and analyze cross-namespace resource references to prevent lateral movement and enforce boundary defense.

What are common Kubernetes namespace security risks in multi-tenant environments?▼

Common Kubernetes namespace security risks include poor workload isolation, improper mixing of trust levels like dev and prod, system namespace abuse, and dangerous cross-namespace references that expose clusters to lateral movement.

How can I detect policy bypasses and rogue namespaces in Kubernetes?▼

Detecting policy bypasses and rogue namespaces requires evaluating configurations for OPA exemptions, privileged security contexts, and excessive privileges that attempt to circumvent multi-tenancy standards and boundary defense policies.

How do I check for cross-namespace vulnerabilities in my cluster?▼

Checking for cross-namespace vulnerabilities involves flagging dangerous resource references, identifying dangling secrets, and locating service accounts that increase the attack surface and compromise workload isolation.

Can I validate Kubernetes multi-tenancy compliance using automated checks?▼

You can validate Kubernetes multi-tenancy compliance by analyzing namespace configurations to ensure proper workload isolation, detect trust level mixing, and prevent unauthorized policy bypasses in production environments.

What are the limitations of namespace-level isolation in Kubernetes?▼

Namespace-level isolation limitations include the risk of structural density issues, dangling secrets, and cross-namespace resource references that can still allow lateral movement if boundary defense policies are not strictly enforced.
