Tema da aula - Title: Fighting Against Cyber Threats From a system perspective
Abstract
Cyber attacks have now invaded our daily lives. According to a report by the European police agency Europol, cybercrime threats are exploding in Europe. Not a day goes by without discovering that an institution or a company has been attacked. In this talk, we will explore how research in systems and distributed systems may improve the resilience to cyber attacks following 3 axes targeting mobile systems, distributed systems, and operating systems: (I) The astonishingly widespread adoption of the Android operating system has been accompanied by the spread of malware across the Android ecosystem at an alarming rate leading to study how to strengthen the robustness of mobile systems such as Android; (II) Peer sampling is a key component of distributed systems for overlay management and information dissemination. It is regularly challenged by Byzantine nodes, leading to a revisit of the field by introducing new algorithms and investigating how SGX hardware enclaves can improve resilience to threats. (III) A significant amount of research focuses on defending against cyber attacks such as ransomware but little on getting systems back up and running once they have been attacked.
