Abstract: Handling uncertainty in cyber security and privacy is an important aspect for security analysis in enterprise communication networks. However, there has been inadequate research effort in studying what modeling approaches could promisingly manage such uncertainty, and how to construct the models to make them useful in practice. In this plenary talk, we aim at presenting intelligent systems techniques and approaches on effectively managing uncertainty modeling for cyber security and privacy, and offer initial evidence indicating that this could be a useful approach. The presentation is centered around vulnerability prediction analytics, privacy modeling, cyberattack and intrusion detection and response modelling. System administrators need to know what is really happening, the scope and severity level of attacks, possible consequences, and probably potential countermeasures. Moreover, they need to know the sensitivity and specificity of the defensive techniques. Although the subject is complex involving many methodologies it will be attempted to report current efforts, including ours, on identifying the important types of uncertainty and on using mainly the intelligent systems approach to capture them for enhanced security analysis. Several examples will be outlined ranging from Markov chain modelling and neural networks to Bayesian network modelling, focusing in the analysis of sensitivity of these models to their parameters perturbation through illustrative preliminary experiments.
Brief Biography of the Speaker: Dimitrios A. Karras received his Diploma and M.Sc. Degree in Electrical and Electronic Engineering from the National Technical University of Athens, Greece in 1985 and the Ph. Degree in Electrical Engineering, from the National Technical University of Athens, Greece in 1995, with honours. From 1990 and up to 2004 he collaborated as visiting professor and researcher with several universities and research institutes in Greece. Since 2004, after his election, he has been with the Sterea Hellas Institute of Technology, Automation Dept., Greece as associate professor in Digital Systems and Signal Processing as well as with the Hellenic Open University, Dept. Informatics as a visiting professor in Communication Systems (the latter since 2002 and up to 2010). He has published more than 65 research refereed journal papers in various areas of pattern recognition, image/signal processing and neural networks as well as in bioinformatics and more than 180 research papers in International refereed scientific Conferences. His research interests span the fields of pattern recognition and neural networks, image and signal processing, image and signal systems, biomedical systems, communications, networking and security. He has served as program committee member in many international conferences, as well as program chair and general chair in several international workshops and conferences in the fields of signal, image, communication and automation systems. He is, also, former editor in chief (2008-2016) of the International Journal in Signal and Imaging Systems Engineering (IJSISE), academic editor in the TWSJ, ISRN Communications and the Applied Mathematics Hindawi journals as well as associate editor in various scientific journals. He has been cited in more than 1725 research papers, his H/G-indices are 18/39 (Google Scholar) and his Erdos number is 5. His RG score is 30.65 ( https://www.researchgate.net/ profile/Dimitrios_Karras2/)
