From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I wouldn’t recommend using anti-virus software. It usually creates a lot more overhead, plus it usually mimics existing solutions already in linux. The only viruses I have ever caught using an anti-virus software on Linux are the test viruses to see if all is working fine.
Anyway, here’s my 20+ enterprise experience recommendations with Linux :
apt
andrpm
tend to have built in functionality to check the state and status of your installed software. Use trusted software repositories only. Often recommended by the distro maintainers. Stay away from use this script scripts unless you can read them and determine if they’re the real thing.Adhering to these principles will get you a long way!

Thank you for the advice!
Firewall on Linux is something I still don't understand, and explanations found on Internet have always confused me. Do you happen to know some good tutorial to share? Or maybe one doesn't need to do anything at all in distros like Ubuntu?
Regarding ssh: you only mean incoming ssh, right?
I don't think you need to configure your firewall. Firewalls are usualy used to block incomming connectings. Usualy a Firewall that blocks all incomming connections is already active on your modem/router. Adding exception to the modem/router Firewall usualy happen through port forwords.
