Personally, if you're trying to protect your system...

A) antivirus-not really a worry on Linux, but if you host files 
for/to/from Windows or run a mail server, use ClamAV.

B) Use a file integrity hasher like Tripwire (may need to google and 
find other "free" ways to achieve this) so you will know when files are 
altered without your knowledge.

C) Install rootkit detection utilities, like rkhunter and chkrootkit.

D) Bastille Linux or using SELinux secures permissions if you have 
multiple users.

E) firewall software.  I find them to usually be a bigger pain than it's 
worth for me, since I'm behind a NAT router usually and I usually only 
run the bare minimum services I use often.

Using all of these is probably overkill for the average user, but 
hey...depends on what you're looking to do.  And this doesn't include 
things you can do like running denyhosts or other means to secure 
individual services.
