The Ultimate Guide to Kubernetes Security [For Dummies]

For information about how Wiz handles your personal data, please see our Privacy Policy.

After reading this guide, you'll be able to:

  • Implement Kubernetes security best practices across every layer—from infrastructure to runtime.

  • Identify and prioritize Kubernetes misconfigurations, vulnerabilities, and access risks.

  • Confidently assess your compliance posture against industry benchmarks like CIS and NIST.

Key Takeaways
  • Why Kubernetes security matters:Kubernetes has become the de facto orchestration tool for modern cloud-native apps. But its flexibility also introduces complexity—and risk. Without a strong security foundation, clusters are prone to misconfigurations, privilege escalation, and exposure.
  • Where to start securing your environment:From image scanning to access controls to runtime protection, this guide walks you through what to secure, when, and how—whether you're a platform engineer or security lead.
  • The importance of lifecycle coverage:Effective Kubernetes security isn’t just about locking things down at runtime. You’ll learn how to “shift left,” enforce least privilege access, and build guardrails into your CI/CD pipeline.

Is this guide for me?

This guide is designed for DevOps, platform engineers, and cloud security professionals responsible for Kubernetes environments. Whether you're hands-on with clusters or shaping your org’s container security strategy, this guide breaks down what you need to know—from fundamentals to best practices.

What's Included?

Kubernetes security foundations: Understand how Kubernetes works, where the risks lie, and what shared responsibility looks like in managed clusters.

Image and container security: Get a walkthrough of the container lifecycle, image scanning strategies, and how to stop vulnerabilities from reaching production.

Access and identity management: Learn how to enforce least privilege using Kubernetes RBAC, namespace isolation, and network policies.

Runtime and compliance coverage: Explore runtime threat detection, audit log monitoring, and how to map your Kubernetes setup to frameworks like CIS and NIST.
