Microsoft's leaner approach to Vista security
Microsoft is talking up support for hardware-based security in Windows Vista, though only a sliver of the company's original plan will make it into the operating system.
Three years ago Microsoft unveiled Palladium, renamed Next-Generation Secure Computing Base (NGSCB) after the original name became tainted with controversy over privacy and fair-use issues and because another company claimed rights to the Palladium name. The technology was to be part of the next Windows release.
NGSCB promised to boost PC security by using hardware and software that would allow parts of a computer to be isolated from malicious code such as viruses and worms. It also would foil attacks that use logging devices by encrypting data as it moves between a PC's hardware components. NGSCB required significant changes to hardware and software.
