What is the best available free internet security package? Is there one? I use Zone Alarm for my PC and was wondering if there is an equivalent for Macs.
Thanks in advance for your help.
I use little snitch and it's very effective to monitor any undesired network activity, like programs trying to communicate from inside a machine to the outer world, and programs from outside trying to open communication channels with your machine.
This application is GUI based, therefore is not for servers but for a desktop machine.
