About

Overview

Ilir holds PhD (2007) and BEng (Honours) (2003) degrees in Software Reliability and Computing respectively from City, University of London. He joined the Centre for Software Reliability (CSR) in July 2003, first as a Research Assistant and then as a PhD student. He was appointed a Research Fellow in January 2009, Lecturer in November 2012, Senior Lecturer in April 2014, and Reader in October 2019.

Since July 2019, he is serving as the Head of Department of Computer Science. Prior to this he has served as Deputy Head of department (2018/19), Director of Undergraduate programmes (2017/18), and the Course Director for the MSc in Management of Information Security and Risk (2012-2018).

He served as Principal Investigator in two projects which investigated the potential benefits of diversity and defence in depth for security: the UK EPSRC-funded D3S project (2015-2018); and the EU H2020-funded DiSIEM project (Diversity Enhancements for SIEMs) (2016-2019).

He has worked previously in the DOTS and DIRC projects, a research project sponsored by the UK Defence Science and Technology Laboratory (DSTL) on technological trends of secure system evolution as well as the EU Framework Programme 6 (FP 6) project ReSIST and EU FP 7 project AMBER. He was the CSR lead on the ReSIST activity FOREVER. He was also a co-investigator in the SESAMO project.

He is a Certified Information Systems Security Professional (CISSP), and a member of IEEE, ACM and BCS.

With colleagues Vladimir Stankovic and Peter Popov, Ilir has setup a spin-off company called ResilSoft Ltd, which aims to commercialise research on diverse databases which formed part of Ilir's and Vladimir’s PhD theses, which were supervised by Peter.

Research

Research

Ilir's research area is Software and Systems Engineering. His research focus is on quantitative assessment of the dependability and security of software-based systems. This focus has led him to research methods for assessing fault-tolerant and intrusion-tolerant systems that make use of “design diversity” – using more the one diverse protection system or end system to increase the overall system dependability and security. Other terms used in literature for “design diversity” are “layered defence”, “defence in depth” and “defence in breadth”. He has been closely involved in most of the security research undertaken at CSR since 2005, co-authoring the papers and proposals that resulted from this research. The research on diversity has included numerous application areas:
- Operating Systems
- Database Systems,
- AntiVirus (AV) products,
- Intrusion Detection Systems (IDSs),
- Static Analysis Tools (SATs),
- Botnet detectors and malicious web crawling detection;
- Biometric Fingerprint Authentication Systems

Currently he is a PI on two research projects: EPSRC D3S (2015-2018) and H2020 DiSIEM (2016-2019).

In 2010-2011 he was involved in a security review of the specifications of the European Railway Traffic Management System (ERTMS) on behalf of the UK railway industry.

He was one of 17 UK researchers to be selected to attend two workshops on Aviation Security organised by the UK Home Office and the US Department for Homeland Security in August and December 2010, which aimed to 'develop an assortment of creative and original ideas to help identify what aviation security could and should be in the year 2027'.

In the summer of 2011 he spent two months on a research visit to the US National Institute for Standards and Technology (NIST). The visit was sponsored by NIST, and he researched open-ended vulnerability testing and assessment methods for electronic voting systems that could be used in US federal elections.

In the last 10 years he has served as a member of the Programme Committee (PC) for the IEEE ISSRE (where he co-chaired the PC in 2017), DSN, EDCC, PRDC and NCA conferences as well as Springer-Verlag SAFECOMP conference. In 2018, he guest-edited a special issue of the IEEE Transaction on Reliability. He has reviewed for various journals including IEEE TSE, TDSC and TR.
