Chaire Cyber CNI – Cybersecurity for Critical Networked Infrastructures

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.

About the research updates at the partners

The chair Cybersecurity for Critical Networked Infrastructures (CyberCNI.fr) has currently six industrial partners: Airbus, Amossys, BNP Paribas, EDF, Nokia, SNCF. There is continuous exchange between the PhD students and the partners. Every six months, there is an additional research update (spring/fall) event that provides the opportunity to see all running works together. In addition, research updates are done with and at specific partners.

The advantage of such an event is having even more people from the respective company present. This permits interesting discussions and regularly leads to even more people following the works of the chair.
