Dr Zonghua Zhang, nouvellement intégré comme membre à SAMOVAR, nous fera un séminaire R3S le vendredi 18 mars 2016 à 10h30 en salle A03, à Télécom SudParis.
Title : Towards Cyber Attacks Mitigation : from Cost-effective Security Hardening to Autonomic Cyberdefense
Abstract : Instead of preventing attacks from happening, which is largely believed to be mission impossible in practice, attack mitigation aims at lessening the impact of, if not completely ceasing, an inevitable attack based on its early detection. This talk is intended to share our experiences and lessons learned from the development of cyber attack mitigation mechanisms in different types of networks, including enterprise networks, wireless ad hoc networks, and software defined networking (SDN). Specifically, in enterprise networks, we show how the security mechanisms like attack graph can be bridged with organization level security metrics to aid security administrators in taking cost-effective countermeasures. Also, we will illustrate the potential of SDN to reshape the landscape of today’s cyberdefense.
Zonghua Zhang is currently an Associate Professor of Institute Mines-Telecom/TELECOM Lille. Previously, he worked as an expert researcher at the Information Security Research Center of National Institute of Information and Communications Technology (NICT), Japan from April, 2008 to April, 2010. Even earlier, he spent two years for post-doc research at the University of Waterloo, Canada and INRIA, France. Zonghua’s research covers a broad spectrum of security topics such as anomaly detection, network forensics, root cause analysis, reputation systems, and security protocols in different type of computer and communication networks. The current targeted scenarios mainly cover the emerging networking paradigms such as Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), as well as Cyber-Physical Systems (CPS) like e-healthcare and Intelligent Transportation Systems (ITS).
