Tighten security

[lexam]

Hello all,

I have Plesk 8.6 installed on my VPS (centos 4.2). I would like to make sure that the server is secure enough, just to sleep better at night... Any suggestions? Where should I start? Any books or tutorials? Maybe some good monitoring tools/advice?

Thank you in advance
