Hey folks 👋

I’ve been working in cybersecurity for years, and recently published a book called "Learning Kubernetes Security, Second Edition" — focused on practical, hands-on scenarios to secure Kubernetes clusters in production.

Instead of being a theoretical overview, the book dives into hands-on topics like:

Common RBAC misconfigurations and how to fix them

Runtime protection with tools like Falco and Tetragon

Using admission controllers for policy enforcement

Audit logs and detecting suspicious activity

Incident response processes for Kubernetes-native environments

Third-Party Plugins using Krew, Cilium, etc.

It’s focused for DevOps, security engineers, and platform teams — especially those working with Kubernetes clusters.

I shared a full breakdown of the content and audience here 👉 https://medium.com/@raul.lapaz/learning-kubernetes-security-2cb906ad8037

If you’re working on K8s security challenges or have favorite tools/approaches, I’d love to hear from you!
