Description
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 high cost to businesses and individuals. Advances in networking such as Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) have enabled the network availability and scalability required to support massive global connectivity. With SDN and programmable networks, we introduce flexibility to the control and processing of network traffic, which may be leveraged for in-network security functions. However, as we explore the use of network programmability frameworks and languages such as P4 to accelerate packet processing functions for the flexible and scalable connectivity in next-generation networks, we cannot lose sight of the security of the programmable network itself. Indeed, this flexibility and programmability potentially exposes the network devices to compromise.This talk will explore the opportunities and challenges of programmable network security, developments in the field, and our related research at CSIT/QUB.

What you never wanted to know about vulnerability databases
Orateur : Henrik Plate - Endor Labs
Vulnerability databases play a crucial role in modern software security, serving as the backbone for Application Security (AppSec) and Software Composition Analysis (SCA) tools. However, the accuracy and reliability of these databases vary significantly, often leading to misinformed security decisions. This talk explores the challenges associated with vulnerability databases, including incomplete[…]-

CHERIoT RTOS: An OS for Fine-Grained Memory-Safe Compartments on Low-Cost Embedded Devices
Orateur : Hugo Lefeuvre - The University of British Columbia
Embedded systems do not benefit from strong memory protection, because they are designed to minimize cost. At the same time, there is increasing pressure to connect embedded devices to the internet, where their vulnerable nature makes them routinely subject to compromise. This fundamental tension leads to the current status-quo where exploitable devices put individuals and critical infrastructure[…]-
