 Computer networking is currently undergoing a transformation: Network control is being consolidated into a centralized “controller” by separating the so-called data plane and control plane. This transformation is what is popularly known as Software-Defined Networking. In this talk we will see how Software-Defined Networks can be exploited by attackers, and on the flip-side, how they can be leveraged to detect network attacks. For example, we will look at topology spoofing attacks, software switch exploitation in the cloud and attacks arising from malicious switches, we will also see novel techniques to detect malicious switches and hosts.

+MNT Reform ist ein neuer tragbarer Computer, der modular aufgebaut und von seinen NutzerInnen modifiziert/repariert/gehackt werden soll. Ziel ist es u.a., das gesamte System zu dokumentieren und Teile per 3D-Druck, CNC usw. austauschbar zu machen. Dabei sind alle von uns (Lukas F. Hartmann und Ana Dantas) entwickelten elektronischen und mechanischen Bestandteile GPLv3-lizensiert. Ich werde eine aktuelle Version des Laptops mitbringen und das System im Vortrag beschreiben, sowie Hürden, Schwierigkeiten und Zukunftspläne erklären.

+Privatization, gentrification and displacement have become common urban topics – affordable housing is an increasingly scarce resource. A large number of experts from different fields are working on this topic – today, we’d like to present an intersection between urban planning, architecture, open source software and 3-D printing which seems to present an alternative to the standard privatized housing market. Mary Dellenbaugh-Losse is a landscape architect and urban geographer working on affordable housing and urban commons. She will present the dilemma of affordable housing in growing urban centers, and discuss new housing typologies and organization structures (tiny houses, commons, cooperatives) which present alternatives to the standard housing market. Jens Meisner is an artist concentrating on 3-D printing. He will present a variety of examples of 3-D printed houses/housing concepts which are currently being developed. His portion of the talk will cover a variety of topics, including:
+
+- Introduction to subtractive and additive manufacturing
+- wikiHouse – An open-source modular house concept
+- Examples of house printing projects
+- Building materials/filaments
+- Pros and Cons of new manufacturing methods
+- Library of Things – A database of open-source design
