No single point of failure: Taking an aerospace design mentality for OT security

Stephen Fisher Davies
Cyber Security Researcher at the Airbus Cyber Innovation and Scouting team

Tuesday, Sept. 13, 2022

In this talk, I will discuss the issues posed by externally accessible operational technology (OT) and the interconnectivity of devices which run critical national infrastructures (CNI). OT and CNI systems previously protected through air gaps and obscurity are now connected to the internet and bolted into IT infrastructure, thereby have a more complex and accessible attack surface. Increasingly sophisticated attacks are now being focused at these systems, as such we need to innovate new methods of protecting these systems against attacks. Many systems cannot easily be upgraded to a modern, supported alternative. Here we will discuss the rising issue of attacks focused on programmable logic controllers, Industrial IOT (IIOT) and the infrastructure which depends on their use. Removing existing single points of failure is one way to improve the dependability of ICS and Industry 4.0, working within the operational constraints of these systems.

This team focuses on cybersecurity and resilience of IT and OT equipment with a focus on industrial manufacturing security. After receiving his BSc in Computer forensics awarded by the University of Glamorgan in 2008, Stephen has spent his career working in the innovation space for the Commercial Data Recovery industry and Digital Forensics for Criminal and other legal investigations. In his previous work as the manager and technical lead of an ISO17025 certified forensic lab, Stephen has a great deal of experience testing and validating Digital Forensic tools to see they provide dependable outputs which are fit for purpose and are reliable for use within criminal investigations. In addition to receiving Police commendations for his work in this time he was fortunate enough to assist in a great number of major investigations as an expert witness for Police forces all over the UK, the National Crime Agency and overseas incident investigations.

Powering our digital lives with 5G

Tuesday, Sept. 13, 2022

LTE and 5G are enabling and supporting the transformation of energy systems as they strive to increase sustainability. Digitalisation and communication are leading to an increasingly connected world while AI techniques are optimizing operations. Innovations in power system services, measurement devices, architectures and legal structures place demanding requirements on the reliability, availability and performance of the communications networks supporting them. Innovations in LTE, 5G and concepts for 6G, are addressing these challenging requirements with new products and services being deployed in the field and tested in field and laboratory trials. They are leading to a new range of sustainable and local energy options for both large and small consumers, producers, and prosumers of energy as the energy landscape transforms. This presentation offers insight into these innovations and how they contribute to sustainable energy systems.

Dr. Fiona Williams is currently a Research Director of Ericsson driving innovations in 5G and energy solutions. She is currently the Co-ordinator of the edgeFLEX H2020 RIA project which is bringing 5G to bear on the issues of expanding the role of Virtual Power Plants in the management of power grids through enabling new power grid ancillary services and the promotion of regulatory change. She built up research, innovation and IPR activities for Ericsson in Germany since 1991 and earlier for Ericsson in Ireland. She set-up and led large-scale collaborative research programmes, organisations and a joint-venture consulting company partly owned by Ericsson. She holds board member and chairperson positions in a range of organisations and is a Fellow of the international Wireless World Research Forum. She studied for her B.Sc. (Hons.) and Ph.D. degrees at the National University of Ireland and as a visiting fellow at Imperial College, London.

Hypervisor-based Architecture for Mixed-Criticality Systems Design and Development

Wednesday, Sept. 14, 2022

The combination of functions with different levels of time requirements in cyber-physical systems (CPS) has always been a concern and a relevant area of research that has generated a large number of theoretical and practical contributions in the implementation of embedded systems. The term mixed-criticality systems (MCS) including functions to be performed with different levels of criticality in the same system has encompassed this series of works. On the other hand, the evolution of processors, especially multicore systems, has made it possible to integrate under the same hardware platform a set of applications of different timing requirements/criticality with the consequent reduction of energy consumption, wiring, weight, etc. In this vision of a single platform running applications of different levels of criticality, hypervisors for critical embedded systems play a key role. The ability to prevent applications from propagating faults and to isolate them spatially and temporally provides very solid elements for the design, development, validation and certification of applications independently. The objective of this keynote is to show the fundamentals and the use of hypervisors for the design and development of embedded systems with enhanced utilization of processor architectures and with important advantages for application development and certification.

Alfons Crespo
Alfons Crespo is full professor at the Universitat Politecnica de Valencia (UPV) and founding member of the Institute of Automatics and Industrial Informatics (AI2) of the UPV. His research area has always been related to real time systems in its different dimensions such as scheduling, execution support including virtualization techniques, programming languages, and design and development of embedded systems. He has collaborated extensively with national and international research groups, especially with control theory groups to combine scheduling techniques with the control to increase the performances of controllers. He has participated continuously for more than 20 years in European and national research projects. One of the results of the work carried out in the different projects is the XtratuM hypervisor that was transferred to the UPV spin-off fentISS for its evolution, industrialization and certification. The XtratuM hypervisor (a product of fentISS) is running on several satellite constellations and space missions. In terms of scientific production, he has co-authored more than 200 journal and conference papers in the field of real-time systems. He has supervised more than 25 doctoral theses and his teaching has focused on courses in operating systems, embedded systems and real-time systems.
