Those are broad areas. I mostly only have experience with programming (JS, js frameworks etc) but Udemy has been somewhat solid as far as course offerings.
I also highly recommend stuff by Wes Bos: wesbos.com/courses His stuff is great.
Also, anyone wanting to truly understand Javascript, I strongly recommend Kyle Simpson's You Don't Know JS: github.com/getify/You-Dont-Know-JS
I don't have any solid recs for CS, and cyber security though, as I haven't dug into those areas.
