Apple’s Snow Leopard Is Less Secure Than Windows, But Safer

Apple users have less protection from viruses and malicious software than Windows users do. But they’re still safer, security experts agree, because so few malware programs target the Mac.

Apple’s new Snow Leopard operating system, which landed in stores Friday, adds a few security enhancements to protect Mac users from malware. But like previous versions of the Mac OS, Snow Leopard lacks security features that are built in to Windows XP, Windows Vista and Windows 7, such as full Address Space Layout Randomization to thwart attacks from malicious code.

That makes Macs more vulnerable to attack, explained Charlie Miller, a security researcher and author of the book The Mac Hacker’s Handbook. But despite its weaknesses, Mac users have no reason to panic — yet. Apple’s PC market share is still roughly only about 10 percent, giving hackers and malicious software coders very little economic incentive to target the Mac.
