F.R.S.-FNRS Fellow, doctoral researcher @ UCLouvain, 2021-2025

For my research, I developed a network security system for Internet of Things (IoT) devices. This system consists of a complex firewall, supporting interactions between different devices in the network.

It is based on the (sound) hypothesis that this kind of devices have a simple network behaviour, which can be expressed in the form of reduced profiles. Those profiles are in turn used as configuration for the security system.

Those profiles also allow to express time dependencies between devices: for instance, if a device A must communicate before device B, the system will be able to block device B's traffic if no traffic coming from device A had been seen beforehand. This concept allows to take into account the interactions between devices, which are common in IoT networks.

This research work was focused on Smart Home networks, but those concepts can be applied to any network where devices showcase a limited and predictable network behaviour.

The follow-up of my research will be dedicated to deeply analyse and automatically extract patterns of IoT network communication.
