Abstract
Embodiments of systems and methods disclosed herein may isolate the working set of a process such that the data of the working set is inaccessible to other processes, even after the original process terminates. More specifically, in certain embodiments, the working set of an executing process may be stored in cache and for any of those cache lines that are written to while in secure mode those cache lines may be associated with a secure descriptor for the currently executing process. The secure descriptor may uniquely specify those cache lines as belonging to the executing secure process such that access to those cache lines can be restricted to only that process.
