Apple has hired the former director of security architecture at One Laptop per Child, Ivan Krstic, according to ZDNet. Krstic developed the Bitfrost security specification for the OLPC project, which he considers a foolproof system to protect against malware attacks. With the new position at Apple, Krstic will be working on core OS security.
The Bitfrost system diverges from typical protection methods by sequestering each program in separate virtual operating systems, instead of reacting to specific viruses. Each program is prevented from causing harm to the computer or accessing protected and sensitive data. "This defeats the entire purpose of writing a virus," Krstic claims.
Despite Apple's ongoing marketing campaigns that suggest the Mac platform is far more secure than Windows systems, the claims have been met with criticism. Pwn2own winner Charlie Miller, who hacked a MacBook in less than a minute, suggested Macs are less secure than PCs. He still recommends Macs for typical users, however, because of the comparatively smaller range of malware that targets the operating system.
