CKS

(Certified Kubernetes Security Specialist)

My journey of exploring Kubernetes security with CKS certification.

I was apporached by a few folks on Slack and LinkedIN to share my journey of CKS and hence thought to create a handy resource to help the community. 

It took me 4 weeks to prep, 5-6 hours each day. I got 78% on my 2nd attempt.

If you practice enough, 2 hours is more than enough (I had arond 18 mins in spare to review my flagged questions. Please know that I'm not a speed reader neither I practice Kubernetes on my day-to-day job. I gradually developed speed and accuracy with practice).

This is a very brief guide for CKS cert which consist resources from various public documents blended with my exam experience.
