Microsoft has abandoned the Trustworthy Computing concept and instead will take an agile process perspective and embed security in each engineering team within the company



From Neowin:

Microsoft was definitely ahead of the curve when it came to security. With the high-profile issues that plagued the early releases of Windows, the company knew that they had to focus on security so created the concept of "Trustworthy Computing" back in 2002. To announce this new initiative, Bill Gates sent an email out to all of his employees, stating:

What I mean by this is that customers will always be able to rely on these systems to be available and to secure their information. Trustworthy Computing is computing that is as available, reliable and secure as electricity, water services and telephony.
