As you are on a dedicated - you should be employing some type of firewall with a specific set of policies. This is outside of Zen Cart itself but a fairly std in setting up a web server.
As long as you are on the www (and you have to be to sell online) you will be vulnerable to attacks.
Watch the logs and yu can block individual IP's or a range of IP's whre you do not intend on selling and/or attacks are beging generated from.





I don't know the server side of this stuff, I am just a lowly web guy, and this is my first venture into this side of things. I'm learning, but I don't want to screw something up due to lack of knowledge. That's why I rely on my server guru.
