Detailed examples throughout this book allow the reader to better understand and apply the introduced techniques with open source software. Step-by-step instructions help to get familiar with the concepts and to better comprehend their inner mechanisms. A log test data set is available as free download and enables the reader to get the system up and running in no time.
This book is designed for researchers working in the field of cyber security, and specifically system monitoring, anomaly detection and intrusion detection. The content of this book will be particularly useful for advanced-level students studying computer science, computer technology, and information systems. Forward-thinking practitioners, who would benefit from becoming familiar with the advanced anomaly detection methods, will also be interested in this book.
lt;b>Florian Skopik is Head of the Cyber Security Research Program at the Austrian Institute of Technology (AIT) with a team comprising around 30 people. He spent 10+ years in cyber security research, before, and partly in parallel, another 15 years in software development. Nowadays, he coordinates national and large-scale international research projects, as well as the overall research direction of the team. His main interests are centered on critical infrastructure protection, smart grid security and national cyber security and defense. Since 2018, Florian further works as ISO 27001 Lead Auditor. Before joining AIT in 2011, Florian was with the Distributed Systems Group at the Vienna University of Technology as a research assistant and post-doctoral research scientist from 2007 to 2011, where he was involved in a number of international research projects dealing with cross-organizational collaboration over the Web. In context of these projects, he also finished his PhD studies. Florian further spent a sabbatical at IBM Research India in Bangalore for several months. He published more than 125 scientific conference papers and journal articles and holds more than 50 industry recognized security certifications, including CISSP, CISM, CISA, CRISC, and CCNP Security. In 2017 he finished a professional degree in Advanced Computer Security at the Stanford University, USA. Florian is member of various conference program committees and editorial boards and standardization groups, such as ETSI TC Cyber and OASIS CTI. He frequently serves as reviewer for numerous high-profile journals, including Elsevier's Computers & Security. He is registered subject matter expert of ENISA in the areas of new ICTs and emerging application areas as well as Critical Information Infrastructure Protection (CIIP) and CSIRTs cooperation. In his career, he gave several keynote speeches, organized scientific panel discussions at flagship conferences, such as a smart grid security panel at the IEEE Innovative Smart Grid Technologies (ISGT) conference in Washington D.C., and acted as co-moderator of the National Austrian Cyber Security Challenge 2017, and as jury member of the United Nations Cyber Security Challenge 2019. Florian is IEEE Senior Member, Senior Member of the Association for Computing Machinery (ACM), Member of (ISC)2, Member of ISACA and Member of the International Society of Automation (ISA).
Markus Wurzenberger is a scientist and project manager at the Austrian Institute of Technology (AIT), located in Vienna, Austria. His main research interests are log data analysis with focus on anomaly detection and cyber threat intelligence (CTI). This includes the development of (i) novel machine learning that allow online processing of large amounts of log data to enable attack detection in real time, and (ii) artificial intelligence (AI) methods and concepts for extracting threat information from anomalies to automatically generate actionable and shareable CTI. Besides the involvement in several national and international research projects, Markus is one of the key researchers working on AIT's anomaly detection project AECID (Automatic Event Correlation for Incident Detection). Among the most prominent solutions developed within this project, Markus and his team created AMiner, a software component for log analysis, which implements several anomaly detection algorithms and is included as package in the official Debian distribution. In 2016, Markus enrolled for his PhD studies in computer science at the Vienna University of Technology, with focus on anomaly detection in computer log data. The subject of his PhD aligns with several national and international research projects AIT is involved in. In 2015 Markus obtained his Master's Degree in Technical Mathematics at the Vienna University of Technology. Since 2014 he is a full-time researcher at AIT in the area of cyber security.
