Kubernetes Security

System Hardening

This course will teach you the concepts for securing the Kubernetes underlying infrastructure.

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. In this course, Kubernetes Security: System Hardening, you’ll learn to secure the underlying Kubernetes infrastructure. First, you’ll explore how to limit the host access and use IAM roles and policies to control what users can do in the Kubernetes nodes. Next, you’ll discover best practices to have in mind while choosing and installing the packages and services in your operating system. Finally, you’ll learn how to secure the network traffic and restrict the kernel usage to make the systems more secure. When you’re finished with this course, you’ll have the skills and knowledge of security needed to perform the hardening of the systems where your Kubernetes cluster runs.

Reviews summary

Practical guide to kubernetes infrastructure security

According to learners, this course provides a practical guide to securing Kubernetes infrastructure, offering actionable advice and useful hands-on labs. Students praise how the instructor explains complex topics clearly, making it highly relevant for security professionals working in production environments. While many find it comprehensive, some learners note that the course assumes familiarity with Kubernetes and Linux basics, suggesting it's not ideal for absolute beginners. A few also felt certain sections could benefit from a deeper dive or more K8s-specific hardening techniques, though recent feedback indicates a strong reception for its core value.

Effectively covers critical system hardening modules.

"I found the sections on IAM roles and kernel restrictions particularly useful."

"I appreciated the emphasis on best practices for OS hardening."

"The course covered critical areas like host access and network security thoroughly."

Instructor effectively clarifies complex security topics.

"The instructor explains complex topics clearly and provides practical steps."

"The instructor's clear explanations and the detailed demos made learning complex topics like kernel restrictions much easier."

"I found the instructor's approach very straightforward, making even tricky concepts digestible."

"This course is incredibly relevant for anyone working with Kubernetes in a production environment. The hands-on labs were excellent..."

"A must-have for anyone responsible for Kubernetes security. The course cuts straight to the point, offering actionable advice."

"I gained actionable insights into securing our Kubernetes clusters. The practical examples were very helpful."

Some desire more in-depth, K8s-specific technical detail.

"Some parts could use a deeper dive, but overall very valuable."

"I felt some parts were a bit generic and could apply to any Linux system, not just Kubernetes. I was looking for more K8s-specific hardening."

"I was hoping for more step-by-step guidance on implementing these security measures. It feels more like an overview than a deep dive."

Requires prior knowledge of Kubernetes and Linux.

"It does assume some familiarity with Kubernetes and Linux, which is fine, but new users might struggle."

"It's definitely for someone with a basic understanding of Kubernetes."

"I struggled with some of the command-line examples. It feels too high-level for me, looking for more step-by-step guidance."
