How To Avoid a Botnet Infection?

Posted by CmdrTaco on from the yeah-good-luck-with-that dept.

Taco Cowboy writes "Two of the networks in the company I work for have been zombified by different botnets. They are taken off the grid as we speak. We thought we had taken precautions against infection, such as firewall and anti-viral programs, but for some reasons we have failed. Is there any list of precautionary steps available?" I'd suggest port blocking 80 for any computer that is detected running a web browser, but that might prevent some percentage of legitimate work.

    Competent users maybe?

    As far as "programming errors" go, I'd label "expect competent users" as "#1".

    I say we take off and nuke the entire [system] from orbit. It's the only way to be sure.

    If you reply, do so only to what I explicitly wrote. If I didn't write it, don't assume or infer it.
