Passive Optical Access Cybersecurity Project of Kaunas University of Applied Sciences Administrative Building

Abstract

A cyber security project for passive optical access in the administrative building of Kaunas University of Applied Sciences has been presented, replacing copper networks with faster, more reliable and more efficient networks based on optical and wireless technologies, while strengthening the network's cyber security. Current technologies for data transmission over copper and optical interfaces were presented and compared with each other, as well as the strengths and weaknesses of these technologies. PON and GPON technologies and their operational features were reviewed. The basics of cyber security were presented. The design part of the project included an overview of the current situation, a conceptual network model, a scan of the target information system and an overview of the results achieved. The technical parameters of the passive optical network were calculated, cyber incident monitoring equipment was presented, network redundancy and reliability parameters were calculated. At the end of the design part, the optical network equipment was selected and deployed and wireless coverage schemes were presented in the brief. The experimental part of the project consisted of modelling the design of the passive optical network, carrying out tests and describing the necessary improvements. Finally, the work concluded with a presentation of the results (conclusions) of the whole project.
