I have been studying for the Certified Kubernetes Security Specialist mostly on the weekends.
The CKS is a practical test, so for the most part I have been spending time on theory and only a little on the practice. I want to see the forrest for the trees. I read the book Certified Kubernetes Security Specialist (CKS) Study Guide by Benjamin Muschko.
On the practical side, I have made it through all of the exercises on Killercoda in a very superficial way. I plan to revisit after switching gears.
I also have two good open source Github repositories that have CKS sample questions, including Muschko's:
- https://github.com/bmuschko/cks-crash-course/tree/master/exercises
- https://github.com/snigdhasambitak/cks
Next step is to go through and understand all of the questions and answers.
Also there is a cool Network Policy visual editor that I plan to understand.
