To effectively combat cyber threats, our network defenses must be equipped to thwart dangerous attacks. However, our software-dominated defenses are woefully inadequate. The Trusted Computing Group has embarked on a mission to use an open standards-based interoperability framework utilizing both hardware and software implementations to defend against computer attacks. Specifically, this group uses trusted hardware called the trusted platform module (TPM) in conjunction with TPM-enhanced software to provide better protection against such attacks. This chapter will detail a brief history of trusted computing, the goals of the Trusted Computing Group and the workings of trusted platforms.
