MS says closed source is more secure (of course)

The Register: “The head of Microsoft’s security response team
argued here Thursday that closed source software is
more secure than open source projects, in part
because nobody’s reviewing open source code for security flaws.

“Review is boring and time consuming, and it’s hard,” said Steve Lipner, manager
of Microsoft’s security response center. “Simply putting the source code out there
and telling folks ‘here it is’ doesn’t provide any assurance or degree of likelihood
that the review will occur.”
