Monitoramento de eventos de segurança de rede através de ferramentas open source

Abstract

With the increasing number of attacks and data breaches, it has become essential to ensure that even low- to medium-complexity networks are properly protected. However, the limited budget for acquiring security tools can pose a challenge in this context. In light of this, the aim of this study is to evaluate the monitoring of network security events using open-source tools in order to assess the feasibility of employing such technologies for network protection. The results showed that tools like Wazuh were effective in detecting suspicious activities, providing valuable visibility into exploitation attempts, credential leaks, and other threats in environments with near-default configurations. This highlights the potential of these solutions as viable alternatives for networks with budget constraints.
