I'm currently in the process of starting an e-cafe; however, one of my major concerns is the security that I'm going to have to have in order to stop schmucks from using my place to commit computer crimes. I was wondering if I could get any suggestions for a server OS that will be secure enough for my needs. Currently I'm checking out Novell for a file server inside to effectively control login time and usage.

I'm relatively new to the security field, and I'm using this business to help further my education at it. I would like to do this correctly off the get go that's why I'm asking for help to do this.

Any other suggestions are welcome since I'm still in the brainstorming phase of my business plan.

Thank you very much for you time
