报告题目:Dynamic Knowledge Interpolation and its Application to Network Security


Application of fuzzy rule-based interpolation (FRI) has been escalating for making intelligent systems viable in solving many challenging real-world problems. However, requirements of such systems may change over time and the supporting static rule models may not be able to provide accurate interpolation results in the long run. Dynamic fuzzy rule interpolation (D-FRI) offers a potential solution to such problems. A particular application is for network security that is often one of the biggest concerns of any organisation irrespective of their size and nature of business.

Intrusion detection systems (IDSs) are a popular and effective security tool for generating alerts to network administrators, in order to inform against possible or existing threats. A standard IDS may be not very effective or even unsuitable for an organisational requirements over a sustained period. This talk will present an application of D-FRI for building an effective IDS. In particular, it will introduce an intelligent IDS that is built upon the most popular open source IDS, Snort via integration with D-FRI. The talk will illustrate how the integration of D-FRI with Snort provides an additional level of intelligence in predicting possible threats. This integration also facilitates dynamic modelling, in terms of a dynamic fuzzy rule base, by promoting new rules based on the current network traffic conditions, helping Snort to reduce both false positives and false negatives. The talk will also cover other applications of D-FRI in network security and thoughts for further development.


Professor Qiang Shen received a PhD in Knowledge-Based Systems and a DSc in Computational Intelligence. He holds the Established Chair of Computer Science and is a Pro Vice-Chancellor (i.e., Vice President) at Aberystwyth University. He is a Fellow of the Learned Society of Wales (aka. the Royal Society of Wales) and a UK Research Excellence Framework (2008-2014 and 2014-2021) panel member (for Computer Science and Informatics), one of the only two overseas Chinese scholars who have been twice appointed to such an important role across all assessment panels by the UK Government. He has been a long-serving Associate Editor or Editorial Board member of many leading international journals (e.g., IEEE Transactions on Cybernetics and IEEE Transactions on Fuzzy Systems), and has chaired and given keynotes at numerous international conferences.

Professor Shen’s current research interests include: computational intelligence, learning and reasoning under uncertainty, pattern recognition, data modelling and analysis, and their applications for intelligent decision support (e.g., space exploration, crime detection, consumer profiling, systems monitoring, and medical diagnosis). He has authored 2 research monographs and approximately 400 peer-reviewed papers, including an award-winning IEEE Outstanding Transactions paper. He has served as the first supervisor of more than 60 PDRAs/PhDs, including one UK Distinguished Dissertation Award winner. Professor Shen is a London 2012 Olympic Torch Relay torchbearer, nominated to carry the Olympic torch in celebration of the centenary of Alan Turing.
