It’s not tough to make a case today for better Mac security than what Apple delivers out of the box. Even though your business systems ship with a first-level firewall, they don’t arrive with any anti-virus software. Apple insists in clever ads that Mac security is not the problem that users find on PCs. That is true, but not because of the Mac’s superior designs. Unix, deep inside the system’s heart, is just as vulnerable as Windows. (Some say even more so; Unix security patches from HP for its business servers are a regular delivery.)

The Mac enjoys an easier time in security because Apple’s product is a less juicy target. Malware and viruses are designed to make money for criminals, and the number of PCs out there running bareback is 10 times the number of Macs. Security by obscurity only works until it doesn’t. It’s just a matter of time, sad to say, before the criminals fan out and try to rob your system of power or privacy or both.

Anti-virus software (AV) is not just the paranoid geek’s tool anymore. The last virus we detected came off a Web page, and we last had data corrupted in 1997. But things have changed since Apple moved to Unix underneath it’s OS. Oh, and there’s that thing called the Internet, plus the Flash videos you may use to gather research (like from the Wall Street Journal’s site, now that they’re owned by Fox.) Flash, and Adobe’s Acrobat PDF files, are a big target for malware today.

You have more than one choice for a commercial AV tool for your systems (that wasn’t the case in ’97). What you buy probably should provide both firewall and virus protection. Two leading companies offer very different value propositions in their AV software. MacScan commits to a fixed price, while another supplier uses a subscription fee+purchase price model.
