Once upon a time, I believed that computers behind the router/firewall on a home network were pretty safe from hacking. Yes, I knew that I could download nasty bits of software from the Internet, but as far as being hacked by access from “my” network, it just wasn’t likely. I didn’t use software firewalls on… Continue reading IceFloor: Harden Your Mac OS X Firewall

Take Your Mac OS X Security to NSA Standards

This week, we’ll discuss how to keep your Mac safe… Continue reading Keep Your Mac Safe For Free (On the Net) Part 2
Keep Your Mac Safe For Free Part 1
Until 2008, I was a Window’s user. One of the things you get used to very fast when using Microsoft’s operating systems is that you need to keep them secure, and do so quickly. I once read that a Window’s machine, without anti-virus, firewall, etc. connected to the Internet had, on the average, about 20… Continue reading Keep Your Mac Safe For Free Part 1
