A number of graph-parallel processing frameworks have been proposed to address the needs of processing complex and large-scale graph structured datasets in recent years. Although significant performance improvement made by those frameworks were reported, comparative advantages of each of these frameworks over the others have not been fully studied, which impedes the best utilization of those frameworks for a specific graph computing task and setting. In this work, we conducted a comparison study on parallel processing systems for large-scale graph computations in a systematic manner, aiming to reveal the characteristics of those systems in performing common graph algorithms with real-world …
Measuring Security: A Challenge For The Generation, Janusz Zalewski, Steven Drager, William Mckeever, Andrew J. Kornecki
Measuring Security: A Challenge For The Generation, Janusz Zalewski, Steven Drager, William Mckeever, Andrew J. Kornecki
Department of Electrical Engineering and Computer Science - Daytona Beach
This paper presents an approach to measuring computer security understood as a system property, in the category of similar properties, such as safety, reliability, dependability, resilience, etc. First, a historical discussion of measurements is presented, beginning with views of Hermann von Helmholtz in his 19th century work “Zählen und Messen”. Then, contemporary approaches related to the principles of measuring software properties are discussed, with emphasis on statistical, physical and software models. A distinction between metrics and measures is made to clarify the concepts. A brief overview of inadequacies of methods and techniques to evaluate computer security is presented, followed by …
A Study Of Forensic Imaging In The Absence Of Write-Blockers, Gary C. Kessler, Gregory H. Carlton
A Study Of Forensic Imaging In The Absence Of Write-Blockers, Gary C. Kessler, Gregory H. Carlton
Security Studies & International Affairs - Daytona Beach
"Best practices in digital forensics demand the use of write-blockers when creating forensic images of digital media, and this has been a core tenet of computer forensics training for decades. The practice is so ingrained that the integrity of images created without a write-blocker are immediately suspect. This paper describes a research framework that compares forensic images acquired with and without utilizing write-blockers in order to understand the extent of the differences, if any, in the resultant forensic copies. We specifically address whether differences are superficial or evidentiary, and we discuss the impact of admitting evidence acquired without write blocking. …
