特任准教授：ベウラン ラズバン フローリン（BEURAN, Razvan Florin）
We welcome students with abilities related to networks and network security who also have good computer programming and/or mathematical skills. Independent thinking and a strong motivation to learn and develop oneself are a must.
Students who graduate will have a deep knowledge of networks and network security. They will be able to develop network-related software and perform network experiments and assessments using various methods: analytical modeling, simulation, emulation and actual trials. Students will also have hands-on network security experience; thus they will be able to deal with cyber-security issues in the real world. Their English paper reading/writing and presentation skills will also improve significantly.

Network emulation and real-time visualization framework.
People have become more and more reliant on the Internet for daily communication. In addition, networks are and will be more and more used to improve people’s quality of life in the context of smart homes, but also in the area of industrial automation. This will lead to a world in which devices and people are all connected to the same network: the Internet of Everything (IoE).
Such a pervasive network infrastructure requires providing guarantees regarding the network performance, so that Quality of Experience (QoE) requirements are met. Network emulation is an experiment technique that makes possible carrying out the performance evaluations needed in this context by recreating a wide range of network conditions.
We developed the framework called NERVF (see figure below) to make possible various complex experiments, including with emulated wireless networks and mobility.
Although network communication makes life more convenient, it also exposes users to risks they must be aware of, such as malware,
phishing, etc. As a consequence, the network applications people use, especially in mission-critical and safety-critical environments,
need to be designed and analyzed from the perspective of such security risks. Furthermore, IT and security specialists must have the practical skills needed to be able to properly handle computer security incidents.
This knowledge can be acquired only partially through theoretical lectures, and it is of utmost importance to have practical experience
with actual threats in order to be able to deal with them in an effi cient and timely manner. This kind of experience can only be obtained in cyber ranges, realistic environments for cyber-security training that we design and implement.

We aim at providing a dynamic environment in which students cani ncrease their knowledge, learn new skills and develop new abilties. We lay a strong emphasis on applying theoretical knowledge in practice, and on hands-on experience with various aspects of networks and network security. Publishing and presenting oneʼs work are highly encouraged and supported.
