    Firewalls and other means of protection


    I just wanted your opinions on what can we do to make our servers safer for us and our clients and the costs involved.

    If it's possible, please give a link or a referral of where we can get more info about a specific mean of doing so (ie. installing firewalls).

    Thanks a lot!

    Best regards,

    Do regular security audits, keep stuff up-to-date...

    Change your root pass freqently.

    Limit root login's to certain users only from certain locations...

    Alot of stuff is just common sense..

    Unfortunately if you are doing web hosting, a firewall is not the end of increasing security. Otherwise your clients will not be able to manage their sites.

    As others have mentioned, there's not a lot of point to a firewall, when you can't predetermine who will log in from where. However, firewalls on certain services for only certain IP's or using TCP wrappers to protect certain users from logging in only from certain IP's is a good idea. It can't hurt.

    Firewalls won't do much, but it's one small thing to add to a lot of things to have better protection, and in a web server environment is usually one of the most trivial.

    However, at the same time firewalls can drop certain packets, you can tear the datagrams apart with certain methods (not to be confused with this only, to be clear), and you can limit things like ICMP to only specific IP classes or a specific IP, etc. So they do still have some uses, but not like they would on a VPN or something.
