K8S Security Policies

What it does

This skill helps enforce and manage security policies within Kubernetes (k8s) clusters. It enables users to define access controls, network policies, and pod security standards to protect workloads from threats and ensure compliance with best practices.

When to use it

• You need to restrict container runtime behaviors to prevent privilege escalation or unauthorized access.
• Your organization requires adherence to regulatory or internal security standards for Kubernetes environments.
• You are setting up a new cluster and want to automate the enforcement of baseline security configurations.

Key capabilities

• Enforces Pod Security Policies (PSP) to control container privileges and resource limits.
• Manages Network Policies to restrict traffic between pods and external services.
• Integrates with Kubernetes Admission Controllers for real-time policy enforcement during deployment.

Example prompts

• "Enforce a pod security policy that disallows root user access in containers."
• "Create a network policy to block all incoming traffic except from the database service."
• "Audit my cluster’s current security policies and suggest improvements based on CIS benchmarks."

Tips & gotchas

• Ensure your Kubernetes version supports the required policy types (e.g., PSPs are deprecated in newer versions; use Pod Security Admission instead).
• Always test policies in a non-production environment before applying them to avoid disrupting running workloads.
