While still not great, the operating systems behind Apple desktops, laptops and phones are getting more secure, researchers at Black Hat \u00a0say.While not recommended for corporate use unless it\u2019s in islands within larger networks, the OSX operating system has made strides, says Alex Stamos, who lead a team of researchers from iSec Partners that researched the OSX and Windows 7 operating systems.Their conclusion is that Apple does pretty well, but Microsoft wins. Even so, earlier versions of Apple\u2019s software were more vulnerable to initial exploitation than Win 7, but the latest Apple version known as Lion makes up ground.CONVERGENCE: \u00a0Apple to have one OS for Macs and iPads by 2016Escalating privileges remains a problem on both operating systems, he says, with OS X having more potential soft spots than Win 7. But when it comes to network vulnerabilities, Apple is the loser. \u201cOSX networks are significantly more vulnerable to network privilege escalation,\u201d he says. \u201cAlmost every OSX server service offers weak or broken authentication mechanisms.\u201dDespite commonly held beliefs that Apple products draw less attention from attackers, some statistics seem to buck that notion, he says. For example, over the past three years, 1,151 common vulnerabilities and exposures (major bugs) have affected Apple products, including third party software. The number for Windows is 1,325, not that much higher, Stamos says.Lion has made strides with the addition of an application sandbox that keeps applications isolated so if malicious executables boot up, they are contained, he says. \u00a0On the mobile side, independent researcher Dino Dai Zovi, says iOS does a pretty good job running applications in a sandbox. The operating system has a dynamic signing feature for applications in which the device itself has to approve applications before running them, not just accepting the Apple certificate that says they are approved.He says Blackberries have better data protection than iOS, but they lack a sandbox for running applications. He says that Google\u2019s Android mobile operating system is more vulnerable than iOS. Android is about as secure as a jailbroken iPhone that has lost many of its security features by virtue of being jailbroken, he says.Read more about software in Network World's Software section.
