Where ML Security Is Broken and How to Fix It
Speaker : Maura Pintor (PRA Lab, University of Cagliari)
To understand the sensitivity under attacks and to develop defense mechanisms, machine-learning model designers craft worst-case adversarial perturbations with gradient-descent optimization algorithms against the model under evaluation. However, many of the proposed defenses have been shown to provide a false sense of robustness due to failures of the attacks, rather than actual improvements in[…] -

Security and privacy in personal data management systems
Speaker : Nicolas Anciaux (INRIA)
Personal Data Management Systems (called PDMS) provide individuals with a hardware and/or software solution to manage their data under control. From a data management and security/privacy perspective, the issues involved are complex and differ significantly from the traditional database setting. The emergence of trusted execution environments (such as Intel SGX) could be a game changer. This[…] -

Contemporary Issues in Digital Forensics
Speaker : Ben Martini (University of South Australia)
The discipline of digital forensics, or as it was then known ‘forensic computing’, began with a focus on retrieving admissible evidence from computer systems (typically personal computers). However, with the increased pervasiveness of connected digital technologies in the last 20 years, a wide variety of new and complex sources of digital evidence have emerged. This has presented a range of[…] -

Programmable Network Security – Challenges and Opportunities
Speaker : Sandra Scott-Hayward (Queen’s University Belfast)
Society’s dependence on communication networks for all aspects of day-to-day living; business, education, entertainment etc. makes “the network” a very attractive target for malicious attack, which cyber criminals are only too eager to exploit, attempting to limit or block access to essential services (e.g., healthcare, banking, critical infrastructure etc.), disrupting our daily lives and causing[…] -

Les cyber opérations, entre opportunités stratégiques et contraintes opérationnelles
Speaker : Stéphane Taillat (Académie Militaire de Saint Cyr-Coëtquidan)
Le recours aux opérations numériques et au cyberespace s’est généralisé dans la gestion des crises et des conflits internationaux. Pour autant, aucune des cyber opérations étatiques ou prêtées à des États n’ont débouché sur des conflits armés ou sur une escalade significative des tensions. A ce titre, cette conférence cherche à s’interroger sur l’utilité stratégique des opérations numériques et du[…] -

A Fundamental Approach to Cyber Risk Analysis
Speaker : Rainer Böhme (Universität Innsbruck)
This paper provides a framework actuaries can use to think about cyber risk. We propose a differentiated view of cyber versus conventional risk by separating the nature of risk arrival from the target exposed to risk. Our review synthesizes the liter- ature on cyber risk analysis from various disciplines, including computer and network engineering, economics, and actuarial sciences. As a result,[…] -
