Abstract(s)
As ferramentas de monitorização de rede desempenham um papel essencial na segurança, disponibilidade e eficiência da gestão de sistemas informáticos. Através da sua utilização é possível detetar de forma precoce incidentes, prevenir falhas e mitigar potenciais ataques cibernéticos. A presente dissertação descreve o processo de análise, seleção e implementação de uma solução de monitorização adaptada ao contexto da empresa Arsopi, na sequência da descontinuação da ferramenta anteriormente utilizada. Para tal, foi efetuado um estudo
comparativo entre três alternativas open source — Zabbix, CheckMK e Nagios Core —, avaliando as respetivas funcionalidades, arquiteturas, compatibilidade, processos de instalação, vantagens e limitações. A análise permitiu concluir que o Zabbix era a solução que melhor se adequava às necessidades identificadas. Na vertente prática, procedeu-se à implementação do Zabbix num servidor dedicado, seguindo um conjunto de medidas de segurança, e à sua configuração para monitorização de servidores, dispositivos de rede e firewall. Foram ainda desenvolvidos itens personalizados, recorrendo a WMI, SNMP e APIs, bem como dashboards adaptados às necessidades da equipa de IT. Os resultados obtidos demonstraram uma melhoria significativa em termos de eficiência operacional, proatividade na deteção de problemas e redução do tempo de resposta a incidentes, sendo o feedback da equipa globalmente positivo. A dissertação conclui que a adoção de uma solução de monitorização adequada, configurada de forma personalizada e segura, representa uma ferramenta estratégica para a resiliência e robustez da infraestrutura tecnológica, contribuindo para uma gestão mais eficaz e para um
aumento da segurança global da rede.
Network monitoring tools play a crucial role in ensuring the security, availability, and efficiency of IT systems management. Their use enables the early detection of incidents, the prevention of failures, and the mitigation of potential cyberattacks. This dissertation describes the process of analyzing, selecting, and implementing a monitoring solution tailored to the context of Arsopi, following the discontinuation of the company’s previous tool. A comparative study of three open-source alternatives — Zabbix, CheckMK, and Nagios Core — was conducted to evaluate their functionalities, architectures, compatibility, installation processes, advantages, and limitations. The analysis concluded that Zabbix was the solution best suited to the organization’s requirements. In the practical component, Zabbix was deployed on a dedicated server, accompanied by a set of security measures, and configured to monitor servers, network devices, and the firewall. Additionally, custom items were developed using WMI, SNMP, and API integrations, along with personalized dashboards adapted to the IT team’s needs. The results demonstrated a significant improvement in operational efficiency, proactive incident detection, and reduced response times, with overall positive feedback from the IT staff. The dissertation concludes that adopting a properly configured and secure monitoring solution constitutes a strategic tool for strengthening the resilience and robustness of technological infrastructures, contributing to more effective system management and enhanced overall network security.
