Systems Security Group

Cyber Security deficiencies constitute a clear, present and future danger.

The identification, assessment and mitigation of vulnerabilities and threats, constitute critical security artefacts. These artefacts require consideration across the entire systems stack, encompassing hardware, software, middleware, networks, and users.

With security as an end-to-end "systems" property, the Systems Security Group (SSG) undertakes fundamental and empirically-driven research, addressing the susceptibility of complex socio-technical systems to compromises.

The SSG group advocates a data-centric view, to comprehensively explore system-level security challenges, spanning data at rest, transit, and over its usage. We research the interplay between vulnerabilities, threats, and impact in order to provide trustworthy (dependable, resilient, and secure) functionality in computer systems. Our application domains include cyber-physical systems, network infrastructure, software, middleware and virtualized environments.

Research members

Antonio's research aims at the integration between theoretical and applied security towards designing secure systems and protecting them. He has a background in theoretical informatics and experience working in the industry. This combination is prerequisite good basis for conducting notable research, while proposing practical solutions. Although he has an interest in several aspects of security, he is currently conducting research in the areas of access control models, policies and systems, Cloud security, Critical Infrastructure Protection (CIP), and formal verification (model checking).

View Antonios's profile

My current cyber security research interests in several key areas; Cyber Risk Management in Complex Socio-Technical Systems and Cyber Physical Systems, with the latter primarily serving as a key problem domain for the former. The primary driver is to explore cyber security risk management concepts that move away from asset centric approaches to include threat agent and effect based frameworks. In addition, the applied domain of this work has moved to focus more on the financial services sector, with the addition of developing an understanding of the nature of cyber risks that lead to systemic issues.

Suri holds the Distinguished Professorship and Chair in Cybersecurity at Lancaster University where he co-directs the university-wide Security Institute. Suri previously held the Chair Professorship on “Dependable Systems & Software” at TU Darmstadt, Germany. Following his PhD at UMass-Amherst, he has held positions at AlliedSignal/Honeywell Research, Boston Univ, Saab Endowed Chair Professorship, multiple sabbaticals at Microsoft Research, and visiting positions at the Univ of Texas at Austin, Academia Sincia, PolyU Hong Kong and Technion.

His research interests span the design, analysis and assessment of trustworthy (dependable & secure) Cloud systems and software. He is an advocate of the data-centric system approach to Cybersecurity, and on the quantification of security.
