Vista more secure than OSX?

osx vs vista

Dino Dai Zovi, the New York-based security researcher who took home $10,000 in a highly-publicized MacBook Pro hijack on April 20, has stated in an interview that he thinks Vista is more secure than OSX.

From your research on both platforms, is there a winner between Mac OS X 10.4 and Vista on security?

I have found the code quality, at least in terms of security, to be much better overall in Vista than Mac OS X 10.4. It is obvious from observing affected components in security patches that Microsoft’s Security Development Lifecycle (SDL) has resulted in fewer vulnerabilities in newly-written code. I hope that more software vendors follow their lead in developing proactive software security development methodologies.
