I previously have had trouble with hackers hacking into servers I was using for web hosting. Does anyone know any good tutorials to prevent it, or perhaps give me some tips on how to increase security? I'm colocating a server soon, so I don't want the same thing happening again. Thanks for the help! :)

EDIT: Or would it be best to hire a professional to secure the server?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

Definitively hire a professional. – mailq Sep 24 '11 at 16:45
Yeah. Thought that would be best, as I don't know much about security so a tutorial wouldn't help really and would be far too risky. Do you know any decent sites that provide security services? :) – Joey Morani Sep 24 '11 at 16:53
In Japan, Singapore or the Bermudas? An expert has to be near to you. So that you can phone him in an emergency and he will be there in a few hours. I can recommend but maybe they are too far away from you. – mailq Sep 24 '11 at 16:55
Yeah. I'm in the UK. No worries I'll ask around and do some searches for a good company. Thanks for the help mailq! :) – Joey Morani Sep 24 '11 at 16:59
See for learning more about security. Also, there are a few consultants from the UK there that would be able to help outside of SO. – Jeff Ferland Sep 24 '11 at 21:22

I'll just leave this here, in case someone finds this post and would like to get a start on server security: nsa guides for sever setup. I would start with the linux server config guide.
