What is the Best Firewall for Servers?

Posted by Cliff on from the hot-protection-for-heavy-iron dept.

Sushant Bhatia asks: "I maintain a bunch of servers (Win 2003/XP Pro) at our labs in the university. Of late, the number of attacks on the computers has been more noticeable. The university provides firewall software (Kerio) but that doesn't work with Win 2003 (works with XP). And so we keep getting hit by zombie machines taken over in the Education Department or from Liberal Arts :-). So what does the Slashdot crowd use when they need to secure their Linux and Windows servers? Does it cost less than US$100?"

    You keep getting hit by zombie machines?

    Liberal Arts zombies? Are you sure they're not dogs?

    (And, as always, the best answer to your question may come from Google. Linux.com | A Linux firewall primer.)

    I've found that for 99% security, the best solution is to unplug the ethernet cable on my server and just use it locally (kind of defeats the point, huh?)

      I say we take off and nuke the server from orbit. It's the only way to be sure.

    agreed. and if your not command line oriented, use the webmin interface to create your rules.

    slightly off topic but does anyone else have trouble reading those annoying "confirmation your not a script images"? The one I am looking at right now is nearly impossible to read.

    When its liberal arts machines getting infected, I've found the BEST firewall to be a pair of wire cutters. NOTHING gets through after the skilled use of these babies.

    I've been running an OpenBSD/PF firewall at home for ages now and the system load has never gone above 0%.

    Have you tried plugging it in?
