Simulative evaluation of security attacks, Master student presentation
Francesco Racciatti, graduating Master's student at the University of Pisa, will present his work:
Simulative evaluation of security attacks in Wireless Sensor Networks and IP-based Computer Networks
Cyber-physical systems and computer networks are exposed to a number of cyber-physical attacks, that can have a severe impact against performance, and service integrity and availability. Although it is important to assure an adequate level of security, it is practically unfeasible to address all possible attacks at the maximum possible extent, due to technical or economic constraints. Hence, even before the system/network deployment takes place, it is vital to understand the impact of security attacks, in order to rank them according to their severity, and address them more effectively and efficiently. We have developed a simulative approach that allows the user to quantitatively evaluate the impact of cyber-physical attacks. Rather than implementing and actually performing the considered attacks, our approach simply reproduces their final effects on the network and application. The user describes attacks through a high-level specification language, and does not need to implement or customize any component of the referred simulative platform. On the basis of this approach, we have implemented two attack simulator prototypes, both built on top of the OMNeT++ platform. The first one is based on the WSN simulator Castalia, while the second one is based on the INET simulator, which is mainly intended for IP-based conventional computer networks. To fix ideas and show the capabilities of our simulators, we consider two realistic application scenarios, and evaluate the effects of cyber-physical attacks against the considered networks and applications.
Francesco Racciatti is a graduating Master's student in Computer Engineering at the University of Pisa, Italy. His Master Thesis project concerns the development of simulative tools to evaluate cyber-physical security attacks and their effects.
