Abstract
Official abstract text for this publication.
A method includes creating a soft whitelist having an entry corresponding to a first guest kernel page in a guest operating system (OS) in a hypervisor environment including a hypervisor. The method also includes receiving an access attempt to a second guest kernel page, and generating a page fault when the access attempt is made to the second guest kernel page. In addition, the method includes determining that the second guest kernel page does not correspond to the entry in the soft whitelist, and denying an execution of the second guest kernel page if the second guest kernel page does not correspond to the entry in the soft whitelist.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: creating a soft whitelist having an entry corresponding to a first guest kernel page in a guest operating system (OS) in a hypervisor environment comprising a hypervisor; receiving an access attempt to a second guest kernel page; generating a page fault when the access attempt is made to the second guest kernel page; determining whether the second guest kernel page corresponds to the entry in the soft whitelist; fixing the page…
