Microsoft is bringing its security, Trustworthy Computing and Engineering Excellence teams together in one group, known as the Trustworthy Computing Team.

The move is part of a broader restructuring of the Windows Core Operating System Division, which will consist of five teams going forward: the Windows Core System team, the Windows Engineering System and Services team, the PC Hardware team, the Trustworthy Computing team, and the Windows Core Architecture team.

But the division's top management remains unchanged under Jon DeVaan, as senior vice president for engineering strategy, who reports to Kevin Johnson, co-president of the platform and services division.

That executive structure was put in place when Microsoft restructured its platform and services division earlier in 2006. The company said that move was designed to better align the existing Windows and MSN assets with Microsoft's overall Live strategy.
