Melhoria da Segurança da Rede de Computadores no Instituto Superior de Ciências da Educação da Huíla

Abstract

Educational institutions are of great importance to ensure the development of a country. Therefore, it is necessary that the academic, administrative and technological entities are constantly improved to guarantee the success of the activities of the respective institutions. The Higher Institute of Educational Sciences in Huíla, in particular, has listed the constant challenge of improving its technological environment, fundamentally with regard to communication technologies as a way of facilitating the sharing of information between all actors in the teaching and learning process. However, exchanging information without adequate security can become dangerous and consequently attract third parties interested in stealing such data and infecting networks, resulting in substantial losses. This research has as an investigation question how to improve security at the computer network level of the Higher Institute of Education Sciences of Huíla? and its general objective was to implement security mechanisms at the level of the ISCED-Huíla computer network. This is an applied quantitative research, in which Bottom-up was used as a network method, which allowed a more detailed approach to each part of the system project. The research was developed in the context of the Instituto Superior de Ciências da Educação da Huíla, following the proposal defended by Valeriano Sunda (2021). Data collection was carried out after completing the surveys, in which four (4) employees responsible for managing the network and fifteen (15) administrative workers who used the institution's computer network participated. After the diagnosis and the triangulation with the theoretical part of the study, the need to implement security measures in the institution's computer network was identified. With the perception of this problem, it was decided to seek to protect the network through the implementation of pfSense technology. With the implementation of pfSense there were significant improvements in computer network security, with emphasis on user authentication on the network via institutional email, firewall rules and web cache.
