SYSTEM AND METHOD FOR MITIGATING TOC/TOU ATTACKS IN A CLOUD COMPUTING ENVIRONMENT

摘要

A computer system, method, and computer program product for mitigating TOCTOU attacks, which includes: as processor requesting measurements representing operation of a first process on a host that is untrusted and based on the requesting, obtaining the measurements, which include a checksum that is a result of a second process executing checksum code to verify at least one last branch record on the host. A processor also determined, based on the measurements, whether the first process was compromised.
