Abstract: The proposed activity concerned lectures on Network Security focusing on the hands-on experience. The course dealt with the analysis, design, and management issues for achieving an effective network security zone. Key concepts and technologies that were presented included Linux firewalls, authentication, type of attacks (DDoS/DOS/DNS) and possible mitigation techniques. An overview of encryption algorithms and security protocols were also presented. Students had to have access to a personal Virtual Machine (VM) in which they flashed a Debian OS (or other Linux distro). By login to their VM they experimented with using Linux firewalls, hardening server security as well as monitoring potential malicious attempts for breaching security.

Abstract: During the last years, Neuromorphic Photonics has attracted the spotlight of attention, due to unique advantages that emerge when combining the merits of integrated photonics such as: high wall-plug efficiency, inherent parallelism and bio-isomorphism of their dynamics with neuro-computational concepts. In particular, biological system’s attributes such as spiking, excitability and plasticity unlock unique computational features that allow a new generation of unconventional photonic “processors” based on concepts such as reservoir computing, liquid state machines and spiking neural networks. These optical concepts are currently implemented using state-of-the-art of photonic technology and aim at addressing high-end machine learning related applications such as: high speed image processing (industry 4.0, machine vision, aerospace etc.), next generation plastic optical networks and high-speed low-power processing in general.

Abstract: Digital signal processing and its synergy with optical signal processing is an indispensable tool which enables high speed communications in either short-reach or long-haul transmission systems. As the baud rate and/or the modulation format complexity increases, the signal processing must become even more elegant so as to protect the transmitted signals from transceiver imperfections and the interplay of chromatic dispersion and fiber non-linearity. Very recently, machine learning techniques and/or hardware accelerators based on neuromorphic computing emerge as two promising ways to enhance the capabilities of signal processing especially in harsh nonlinear environments for symbol rates exceeding 50 Gbaud.
The seminar provided a state of the art overview of the emerging neuromorphic computing and machine learning techniques and models towards the mitigation of transmission impairments in optical communication systems.

Dr Marcos Anastasopoulos
University of Bristol, UK
Dr Markos Anastasopoulos has presented a tutorial of “Network Modeling” under the frame of an ONDM-2019 Summer School. The Summer School has offered a set of presentations, addressing MSc and PhD students in the areas of Optical and 5G Networking.
The main purpose of the tutorial was to present to the SMARTNET students the basic principles and methods for developing optimization models applied in the design of smart communication and sensors networks. This set of lectures was focused on optimization problems and methods for traffic routing, flow, and resource capacity optimization. The design models and considered methods were mainly used for backbone and core telecom networks as these are among the most challenging due to their scale, complexity, and cost. Emphasis was given on explaining the principles and methods of network modeling and optimization in a comprehensive, unified, generic, and precise manner. To achieve this goal by the lectures that was given presented the problems on a level of abstraction to avoid unnecessary complexity aiming at helping the Erasmus Mundus students to understand the basics, developments, and recent advances in network design. To cover the major issues in the design of smart telecom networks, the following topics were addressed:
- modeling techniques for developing and formulating various design problems;
- multi-layer modeling of networks comprising different technologies (and functionalities); and
- development of network protection and restoration mechanisms.
