Sustainable Security & Safety: Challenges and Opportunities

Authors: Andrew Paverd, Marcus Völp, Ferdinand Brasser, Matthias Schunter, N. Asokan, Ahmad-Reza Sadeghi, Paulo Esteves-Veríssimo, Andreas Steininger, and Thorsten Holz

Published in: OASIcs, Volume 73, 4th International Workshop on Security and Dependability of Critical Embedded Real-Time Systems (CERTS 2019)

Abstract
A significant proportion of today’s information and communication technology (ICT) systems are entrusted with high value assets, and our modern society has become increasingly dependent on these systems operating safely and securely over their anticipated lifetimes. However, we observe a mismatch between the lifetimes expected from ICT-supported systems (such as autonomous cars) and the duration for which these systems are able to remain safe and secure, given the spectrum of threats they face. Whereas most systems today are constructed within the constraints of foreseeable technology advancements, we argue that long term, i.e., sustainable security & safety, requires anticipating the unforeseeable and preparing systems for threats not known today. In this paper, we set out our vision for sustainable security & safety. We summarize the main challenges in realizing this desideratum in real-world systems, and we identify several design principles that could address these challenges and serve as building blocks for achieving this vision.

4. 8102 Working Group – Attack Taxonomy

Authors: Marc Daciér, Hervé Debar, Thorsten Holz, Engin Kirda, Jan Kohlrausch, Christopher Kruegel, Konrad Rieck, and James Sterbenz

Published in: Dagstuhl Seminar Proceedings, Volume 8102, Perspectives Workshop: Network Attack Detection and Defense (2008)

Abstract
The starting point of this working group was the question about the kinds of attacks that can be detected by inspecting in network traffic. In general, we identified four major problems that network-based intrusion detection systems are facing: 1. Encrypted network traffic 2. Application-level attacks 3. Performance 4. Evasion attack.

6. 08102 Working Group – Requirements for Network Monitoring from an IDS Perspective

Authors: Lothar Braun, Falko Dressler, Thorsten Holz, Engin Kirda, Jan Kohlrausch, Christopher Kruegel, Tobias Limmer, Konrad Rieck, and James Sterbenz

Published in: Dagstuhl Seminar Proceedings, Volume 8102, Perspectives Workshop: Network Attack Detection and Defense (2008)

Abstract
Detection of malicious traffic is based on its input data, the information that is co-ming from network-based monitoring systems. Best detection rates would only be possible by monitoring all data transferred over all network lines in a distributed net-work. Monitoring and reporting this amount of data are feasible in neither today's, nor will be in future's systems. Later analysis like stateful inspection of the traffic imposes even more processing costs. But only at this level of monitoring and analysis there may be a chance to capture all attacks inside a system. So there needs to be a trade-off between detection success and the processing costs.
