Any tips on securing a server?

[Ben Hodgson]

Hi,

I have set up an internet server running qpopper, exim, webmin, apache and ProFTPd and have finished configuring the servers themselves. Now i'm trying to move onto security and protecting the machine from potential attacks.

Does anyone have any tips on doing this (in particular I am trying to protect againt people uploading and executing scripts to temp using a file upload form on a php powered website - ive had that done to me before!)?

Thanks,


Ben Hodgson
