'Palladium', Microsoft's name for what was also known as the "Next Generation Secure Computing Base" (NGSCB), a new security architecture for Windows, will still be in Longhorn, according to Microsoft, but with a few modifications from its original plan.
The original intent was to have developers write custom code that would run in secure isolation zones, called "scenarios", to capture login information and such, theoretically making it harder for attackers to get at said sensitive info. The new model uses Windows programming interfaces rather than the custom code approach, the thought being to reduce the amount of code developers have to write to take advantage of the secure login. Palladium will also allow companies to run "scenarios" containing their own code, something that has always been a scheduled feature, but seems to be drawing less focus now than before.
