Arquitectura Modular de Ciberseguridad Basada en Software Libre
This document presents the proposed design of a prototype logical infrastructure for the
. operation of CSIRT-UNAD, based on the evaluation and selection of open-source tools. The proposal articulates a modular ecosystem that integrates Wazuh (correlation and monitoring), Suricata (network intrusion detection), ELK Stack (log storage and visualization), TheHive and Cortex (incident management and automation), and MISP (threat intelligence). The model covers the entire incident management cycle and aligns with frameworks such as NIST, ENISA, and SIM3 v2, as well as national policies (CONPES 3995) and UNAD’s Institutional Development Plan. The results demonstrate technical feasibility and cost-effectiveness, as well as its value for applied research, academic outreach, and interinstitutional cooperation, positioning CSIRT-UNAD as a sustainable university benchmark.
