Security of HPC Systems: From a Log-analyzing Perspective

Abstract

High Performance Computing (HPC) systems mainly focused on how to improve performances of thecomputing. It has competitive processing capacity both in terms of calculation speed and available memory.HPC infrastructures are valuable computing resources that need to be carefully guarded and avoid beingmaliciously used. Thus, vulnerabilities are quintessential issues in HPC systems due to most of jobs andresources run or stored usually are sensitive and high-profit information. In this survey, we comprehensivelyreview securities of HPC systems from a log-analyzing perspective, including well-known attacks and widelyused defenses, especially intruder detection methods. We found that log files are used for the security purposesmuch less than what we expected. How to use all the available log files comprehensively and employ state-ofthe-art intrusion techniques to improve the robustness of HPC systems still lies for future research.
