Abstract: A computer implemented method for assessing endpoint security includes identifying a size of exposed PCIe space corresponding to a system of interest comprising one or more endpoints, determining an observable state of correct functionality for the system, generating random transaction layer packets corresponding to the endpoint, injecting the generated transaction layer packets, monitoring the system following the injection of the generated transaction layer packets for erroneous patterns exhibited by the system, and reporting the erroneous patterns exhibited by the system. A corresponding computer program product and computer system are also disclosed.

Abstract: Various embodiments are provided for securing data compression in a computer environment are presented. Encryption cycles of a data compression stream may be optimized by applying a first type of encryption on a first section and a last section of compressed data and a second type of encryption on a middle section of compressed data, the first type of encryption containing key information relating to the middle section of the compressed data.
