Abstract
Process credential protection in a virtualized system is described. In-guest process credentials of a guest operating system are registered including binding the process credentials with the following values: a guest address of a first structure that includes subjective credentials, a guest address of a second structure that includes a context in which the process credentials reside, and data fields of the first structure that are not subject to change. A first tag is created from at least the information bound with the process credentials and stored. An integrity verification check is performed at a verification point that is triggered by a function or system call being called by the guest operating system, and includes creating a second tag from at least the information bound with the process credentials and determining if the first tag and second tag match. If they do not match, then the integrity of the in-guest process credentials has been compromised and remedial action is taken.
