Gatekeeper Slams the Door on Mac Malware Epidemics
There are three ways to attack a computer — gain physical access, hit it over the network, or trick the user into running something they shouldn’t. Macs are reasonably well protected against two of the three.
If you use a strong password and encrypt your hard disk using FileVault, only a sophisticated attacker can get in. Up-to-date Macs are reasonably secure against direct network attacks, and when vulnerabilities do crop up, a combination of anti-exploitation features makes it a lot harder for the bad guys (at least on Mac OS X 10.7 Lion). So for physical and network attacks, we Mac users are in pretty good shape.
But the third kind of attack? Well that’s a bit of a problem, since we humans, even the most paranoid of us, can fall prey to trickery. It’s a problem we haven’t had very good solutions for... until now.
OS X 10.8 Mountain Lion includes a transformative security technology called Gatekeeper. It’s a major new advance in operating system security designed to reduce dramatically the ability of an attacker to trick users into installing malicious software. It could be the key to preventing a future widespread malware epidemic.
Don't get me wrong, the iPad is masterful piece of hardware and software (mostly) engineering, but it isn't for everyone and I, like most people, want to encourage competition across the industry because even the iPad lovers win when that happens. by
