Chaire Cyber CNI – Cybersecurity for Critical Networked Infrastructures

Key Attack Strategies Against Black Box DNNs

At the 2022 IMT Atlantique research seminar, Yassine Hmamouche presented our joint works on “Key Attack Strategies Against Black Box DNNs”. This work happens in the frame of an intra-school collaboration project with Yehya Nasser and Amer Baghdadi of IMT Atlantique Brest that are experts on hardware security. For the chaire cyberCNI.fr this work is relevant as it complements our work on security of hardware systems coming form the software side.

Participation at the RESSI 2022 -THE event of the French security community

The chaire cyberCNI.fr participates at the “Rendez-vous de la Recherche et de l’Enseignement de la Sécurité des Systèmes d’Information” (RESSI) 2022. RESSI is a scientific event that aims to bring together and animate the French-speaking community of academic and industrial research and teaching related to the security of information systems.

Cyber CNI 2021 fall Research Updates: Update of our Platform

The cyberCNI.fr (https://cyberCNI.fr/) Research Update (Spring/ Fall) happens once per semester. It is the big status event of the chair Cyber CNI. All works around the chair are presenting their progress, current works, and next challenges. In this talk, our research engineer Fabien Autrel presents how we improved our testbed based on Fischertechnik and CyberRange technologies.

Cyber CNI 2021 fall Research Updates: revue of the year 2021

The cyberCNI.fr (https://cyberCNI.fr/) Research Update (Spring/ Fall) happens once per semester. It is the big status event of the chair Cyber CNI. All works around the chair are presenting their progress, current works, and next challenges. The year 2021 was rich of activities. In this talk, our chairholder Marc-Oliver Pahl presents an overview of the most important activities of the year. The perfect possibility to catch up with the ecosystem of the chaire Cyber CNI.

Chaire CyberCNI @EDF Paris (21.9.2021) – Hassan CHAITOU, Security risk optimization for learning on heterogeneous quality data

On Sep 21, 2021, we had the pleasure to visit our partner EDF in Paris Palaiseau! Here is another highlight presentation:

Hassan CHAITOU, Security risk optimization for learning on heterogeneous quality data
A classifier is a component used in the automation of “decision-making” or complex data abstraction: intruder detection, speed limitation extraction. For an efficient classifier, the training must be on a large volume of data and be renewed over time by integrating or revoking certain learning data. From a security point of view, this process represents a risk since it offers the attacker various ways of degrading classifier performance (either by forcing classifications mischievous, either by randomly degrading its performance). These two types of attacks require more or less effort from the attacker.

This risk is exacerbated when data comes from sources (network equipment, organizations) corresponding to heterogeneous trust levels. Hassan’s thesis aims at controlling the risk associated with this update via game theory in the case where the confidence in the learning data is not homogeneous.

Chaire CyberCNI @EDF Paris (21.9.2021) – Julius BÜNGER, Keeping software in massive IoT installations up-to-date

On Sep 21, 2021, we had the pleasure to visit our partner EDF in Paris Palaiseau! Here is another highlight presentation:

Julius BÜNGER, Keeping software in massive IoT installations up-to-date
Julius’s thesis will provide solutions to ease the IoT device recycling. An object may become unusable for several reasons, for example a hardware failure, no more energy from the battery or obsolete functions. In that case, it is important to decommission the device, and recycle it. One solution for recycling is to re-use the object in a different application or deployment, if it embeds the necessary functions. It can also be disassembled and its parts can be sent to different recycling industry. In order to make this possible, we need to address the issues of localization, keep-alive,classification and security.

Participation at the panel “Cyber security & Digital policies” at theYoung Security Conference 2021

On July 13, 2021, I have the pleasure to be invited as panelist at the Young Security Conference.
The Young Security Conference (YSC) aims at connecting young thinkers with policy experts and academic scholars in a dialogue about the future of European security and defense.
I will participate in the panel “15h30 – 17h30: Afternoon Session III: Cyber security & Digital policies”.
