Resilient Networking 2023

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.


The Lecture is held in English.

The lecture is going to be given on Fridays, 09:45–11:15. We will organize the reading group during the first lecture, so please try to make sure that you participate in this event, at least. The first reading group will then take place in December.

Alike the past years there's a limit of 16 students who can participate in this course, as the reading group does not scale to larger groups.

Please register in the ILIAS course so we have an overview of the participants. The registration will open October 1st, 2023.

Please register to the mailing list.

Reading Group

The course consists of a lecture (3SWS) and an exercise course (1SWS). The exercise course is organized as a 'biweekly' reading group. This means that we will read papers from the context of the topics in class. Everybody is expected to read all mandatory papers (around 9), and we will choose volunteers for each paper to briefly summarize the content, before the entire group discusses their questions and comments regarding the paper (please refer to the template below, the presentations aren't intended to be full-fledged, as in a seminar).
We hope to discuss two papers during each session.

There is a PDF template that you can use to prepare your paper for the reading group.
There is an etherpad to facilitate organization and coordination of the reading group.
