New to DevOps interested in security

Hi everyone,

I’ve just started to learn DevOps. A friend of mine told me to start with OSI model and it works perfectly.

I am about to start my first job in the “security” field using DevOps. Can you guys recommend me where to start from, courses, tutorials, what tools should I use for learning etc?

Thank you so much!

watch youtube videos and start first with linux command both in basic and advance level.
second learn coding like shell script or python
third learn docker full course
fourth learn about CI/CD
