Which Linux distributions are you using for running Zope and how easy it was for you to maximize security of your server?
Red Hat Linux 6.2 here. After a standard install, download and install latest release of SSH. Open '/etc/inetd.conf', comment out all services. Save and do a 'killall -HUP inetd'. Do 'ntsysv' and disable everything you are not going to use on that machine (typically sendmail, nfslock, identd, portmap etc.). Reboot after that. That's what I do first. After that, get all the Red Hat updates from a nearby mirror. Install all, make sure you've got at least a 2.2.16 kernel. Rebooting is not gonna hurt, check what services are started as the machine boots. Get Bastille Linux (http://www.bastille-linux.org) and lock down the box, leaving only 22 and 80 open to the outside world. Well, maybe not that extreme but you get the drift :) Check '/etc/hosts.allow' and '/etc/hosts.deny' to make sure that only the absolute minimum of hosts is allowed access to the server. The latter should contain something like 'ALL: ALL'. That catches most of the script kiddies. Still won't stop a real cracker though, for that you need more. Much more. Read the various docs, keep a tab on updates at Red Hat, SANS, Bugtraq etc. And remember, only the paranoid survive in network security :) Other Linux distros are similar, but this is the one I know :) HTH Jonathan
