I joined Microsoft in 2003 maybe two weeks after SQL Slammer to do internal security work. &quot;Dramatic&quot; is a pretty good way to describe the situation. There were some very hostile debates even over very small bugs that got escalated to the executive level to which the answer was more or less &quot;what part of the policy is unclear? fix it&quot;. It&#x27;s an impressive transformation and I wish, say, Apple were that good. I had hopes for Apple when someone I knew from the Windows group went there but it doesn&#x27;t seem from outside like the company really prioritizes security to the same degree as MS.
