Description: The lecture resilient networking provides an overview on the basics of secure networks as well as on current threats and respective countermeasures. Especially bandwidth-depleting Denial of Service attacks represent a serious threat. Moreover, over the last years the number of targeted and highly sophisticated attacks on company and governmental networks increased. To make it worse, as a new trend at the moment, the interconnection of the Internet with cyber physical systems takes place. Such systems, e.g., the energy network (smart grid), trans- portation systems and large industrial facilities, are critical infrastructures with severe results in case of their failure. Thus, the Internet that interconnects these systems has evolved to a critical infrastructure as well.

The lecture introduces the current state-of-the-art in the research towards resilient networks. Resilience-enhancing techniques can be generally classified in proactive and reactive methods. Proactive techniques are redundancy and compartmentalization. Redundancy allows to tolerate attacks to a certain extent, while compartmentalization attempts to restrict the attack locally and preventing its expansion across the whole system. Reactive techniques follow a three step approach by comprising the phases of detecting an attack, mitigate its impacts, and finally restore a system's usual operation.

Short bio:  Thorsten Strufe is professor of IT Security at Karlsruhe Institute of Technology (KIT/KASTEL), and adjunct professor for Privacy and Network Security at TU Dresden. He is a deputy speaker of the Excellence Centre for Tactile Internet with Human-in-the-Loop (CeTI), and a PI in the national IT security competence center KASTEL Security Research Labs.

His research interests lie in the areas of privacy and network security, especially in the context of social networking services and novel mixed reality applications. Recently, he has focused on studying privacy implications of user behavior and possibilities to provide privacy-preserving and secure networked services.

Previous posts include faculty positions at TU Dresden, TU Darmstadt, and Uni Mannheim, as well as postdoc/researcher positions at EURECOM (France) and TU Ilmenau.
