Educational cybersecurity through the protection and intrusion detection of computer networks 202 65

Abstract

Educational cybersecurity has become a priority due to the increasing number of threats in school networks. In upper secondary education institutions, the lack of access control, the presence of open ports, and the improper use of passwords create vulnerabilities that compromise the integrity, availability, and confidentiality of information. This study proposes strengthening security through network hardening and the implementation of intrusion detection systems (IDS), such as Suricata. Through a mixed methodological approach exploratory, descriptive, and experimental a diagnosis of the network infrastructure is carried out, followed by the configuration and implementation of the IDS to monitor traffic in real time and detect malicious activities. Expected results include a reduction in security incidents, optimization of network performance, and an improved capacity to respond to threats. Network hardening, combined with intrusion detection, not only helps prevent attacks but also strengthens technological management in educational environments. In conclusion, the adoption of these strategies contributes to creating safer, more reliable, and efficient digital spaces, promoting academic development and the protection of institutional data.
