DeepSec 2024 Talk: Living on the Edge: eBPF Defenses for Embedded System (in the Automotive Domain) – Reinhard Kugler (

Sanna/ September 20, 2024/ Conference/ 0 comments

Linux has become a driving factor in the industrial and automotive domain. Vehicles are already a complex network of electrical components. In recent years, the technology stack and connectivity of vehicles have drastically evolved. Is all this complexity still safe and secure? How can embedded systems running different bus systems and physical interfaces be protected against modern attackers? The now mandatory updates of on-board components in these vehicles have introduced even new security challenges to this evolving landscape. Common Linux security measures, including capabilities, permissions, and mandatory access control, are already hitting their limits. Using eBPF technologies promises a flexible way to define security at runtime without the need to change the application code. Will this be as transformative for the embedded sector as it has been for the cloud? This talk presents hands-on

DeepSec 2018 Talk: Suricata and XDP, Performance with an S like Security – Eric Leblond

Sanna/ November 2, 2018/ Conference, Security

extended Berkeley Packet Filter (eBPF) and eXtreme Data Path (XDP) technologies are gaining in popularity in the tracing and performance community in Linux for eBPF and among the networking people for XDP. After an introduction to these technologies, this talk proposes to have a look at the usage of the eBPF and XDP technology in the domain of security. A special focus lies on Suricata that uses this technology to enhance its performance and by consequence on the accuracy of its network analysis and detection. We asked Eric a few more questions about his talk. Please tell us the top 5 facts about your talk. Packet loss really matters. A threat detection engine like Suricata is losing 10% of IDS alerts if it misses 3% of traffic. And there are 10% of incomplete file
