I'm posting this on behalf of
Andrew Fryer who usually posts to TechNet but today has something developer focused for us:
"Glenn Pittaway the Group Program Manager for the Secure development Lifecycle (SDL) talks about the past present and future of SDL. The SDL methodology is at the core of all development work that has an internet facing element (i.e. virtually everything!) at Microsoft. You might argue that this gives this gives Microsoft developers an edge over the competition as they can write more secure code more quickly, however these same SDL resources are also publicly available so you can adopt the same approach in your organisation."
