    Hi
    Thanks for claryfying things. Currently my mandrake firewall is configured
    to those settings that you mentioned (all boxes were left unchecked)..I also
    plan to get SNORT as well.

    So its harder for internet attacks to infect a linux box because the
    programs need root permision in order to modify system files etc. I see.
    But I'm a little unclear by what you mean by:

    don't log in as root (unless it's to a console as "su root"), etc. Most
    malicious
    software vulnerabilities (i.e. adware/spyware) are not possible with linux
    due to restrictions: to install software you must be root.

    Do you mean that after boot up if I log in as root and start an X windows
    environment I'm more vulnerable while connected to the net?? ie malicious
    code is able to now do harm?
    But logging in normally (not root) and later opening up a console window and
    logging in it as root while connected to the net is okay?

    thank you
    Joseph
