Microsoft "Borrows" OSS Security Approach

According to the story:

Microsoft is taking a page out of the open-source community's book where it comes to security. In Windows Vista Beta 2, released last week, the company included a feature called address space layout randomisation (ASLR), a method of foiling some classes of attack that has usually been associated with open-source projects.

Strange move, given that open source never innovates, as Microsoft likes to point out.
