You can also install Damn Vulnerable Linux
Even Windows users are advised to run WGA and update often.

If you have run a web site for any length of them, you will see there are
probes all the time for vulnerabilities (e.g. phpmyadmin, various bulletin
boards and forum software, various CMSs, awstats, as well as Windows
specific probes for IIS and MS-SQL ..).
All these look for systems that are not updated and exploit wholes in them.

On the server, Linux is on par, if not more prevalent than Windows, and
there are worms out there for both. But the success rate is more on Windows,
e.g. Code Red, Nimda, ...etc.
The attacks target unpatched or poorly administered systems.

No longer the case with Ubuntu and the like ...
There is an icon you click and you are up to date. No need for command line
