In regard to trusted computing, what is a policy?

A policy, in the context of trusted computing, denotes a statement that outlines the information security expectations for a system. This definition captures the essence of what a policy aims to accomplish—it sets the framework within which security measures are designed and implemented. Policies play a crucial role in guiding how a system should protect data, manage access, and respond to potential security threats, ensuring that the necessary controls and procedures are in place to maintain the integrity, confidentiality, and availability of information.

The other definitions might touch on specific aspects of access control or rights within a system but do not encapsulate the overarching concept of a policy as it relates to overall security expectations. Access rights granted to processes or users are essential components of a policy, but they are not the complete representation of what a policy entails in trusted computing. Policies provide the foundational guidelines that inform those rights and privileges, supporting the broader objective of achieving comprehensive information security within the system.
