Essential security for Linux servers (2013)
Everytime I read something about Linux server hardening, I get more confused. We&#x27;re lacking a clear and simple, modern guide on how to do things. I know, every setup is different, but there should at least be consensus for a fresh installation.<p>Also, do I really HAVE to change something so that it is secure? Isn&#x27;t a Ubuntu server secure out of the box? With a strong, unique root password of course.
