[LUG] Security considerations on internet facing VPS server

 

Hi folks,

I've been asked by a friend of mine to setup his VPS server so he can stream Shoutcast streams for his online radio station.

Basically he had a server before hosted with a different VPS and something went wrong and things were deleted. I'm not sure if it was someone falling out with him and deleting everything off the server, the VPS having a problem or someone breaking into the server and doing naughty things.

Anyway this new VPS server is with 1&1, so far it's got a basic install of CentOS 5 with the Plesk Control Panel. I have asked him if he'd mind if I replaced this with Ubuntu or Debian which I'm more familiar with (which are other OS options that 1&1 offer).

One of my concerns though is securing the server as it's got a direct connection to the internet. I wondered if anyone had any experiences of packages like Rootkit Hunter or Chkrootkit with Portsentry (I've done a quick search online and these came up as options).

Basically I'm wondering how exactly I should go about installing such packages and if one is favoured over the other?

I presume that things like Rootkit hunter should be installed on a fresh system?

Ta,

Rob
