Hi!
I'm looking for the book Network security essentials 2nd or 3rd edition by William Stallings, I live in europe (EU) and can't find it anywhere. So I just wonder if you guys know a place where I can get it as an eBook (legal! Paperbacks too, if it's inside EU) or if there is an equal good or better book that you can recommend me to read instead/also.
Cheers!
