About the Project

Project description

Este proyecto surge del Trabajo de Fin de Máster (TFM) del Master en Ciberseguridad, titulado «Metodología para la implementación de un SIEM open-source robusto en organizaciones de la Administración Pública»

The main objective of the research is to develop a detailed methodology for implementing a robust open-source SIEM (Security Information and Event Manager) in government organizations. Using innovative approaches and open-source tools, it seeks to improve public sector entities' cybersecurity posture and protect critical infrastructures and citizens' data.

Background

These studies are essential because they explore how implementing open-source tools in public organizations with budget constraints and limited resources can be critical to addressing cybersecurity challenges in Latin America and the Caribbean (LAC). Given technology's growing role in government management, understanding how these tools can strengthen cyber defenses and protect critical data is essential to ensuring security and trust in digital services.

Implementing a Robust Open-Source SIEM: A Methodology for Strengthening Public Sector Cyber Defense

This study presents a methodology for implementing an open-source tool to strengthen cyber defense in response to growing cybersecurity challenges in public administration. It highlights the advantages of open-source software in terms of cost and flexibility, especially given the budgetary constraints and lengthy administrative processes that hinder technology adoption in many LAC countries. In addition to implementation, other open-source solutions are integrated to extend cybersecurity capabilities, thus providing a holistic approach to addressing threats in the digital environment.

Resource 1: Glossary

The glossary defines key cybersecurity terms for implementing SIEM (Security Information and Event Management).

Resource 2: Manual

The user manual provides detailed instructions and case studies for using the open-source SIEM. Its clear and straightforward steps guide users through monitoring and managing the SIEM to strengthen cyber defense.

Resource 3: Guide

The practical guide provides a step-by-step approach to implementing Wazuh SIEM in government organizations. From scope definition to integration with other tools, this guide provides detailed guidance to ensure a robust, sustainable, and successful implementation of open-source SIEM.

General Objective

This project aims to improve organizations' cybersecurity posture for detection, response, and protection against cyber threats by creating a methodology for implementing an effective open-source SIEM tool.

Specific Objectives

1. Research current best practices and approaches to implementing SIEM systems, including using resources such as a glossary to ensure an understanding of key terms.

2. Design a detailed methodology that covers the entire process, from planning and integration to ongoing management of an open-source SIEM in organizations. The methodology should include developing resources such as a user manual and a guide to facilitate the tool's operation and configuration.

3. Test and validate the proposed methodology in simulated and real-world environments to evaluate its effectiveness and feasibility in different organizational contexts, using resources such as a comprehensive guide to orient the process.

4. Provide specific recommendations to improve the implementation and management of open-source SIEM, emphasizing resource optimization and leveraging existing resources.

Findings and Results Achieved

Implementing a Robust Open-Source SIEM: A Methodology for Strengthening Public Sector Cyber Defense

The project proposes a sound methodology for implementing a robust open-source SIEM in public organizations, highlighting Wazuh as the most suitable tool.
The proposed methodology prioritizes defining the scope and requirements for deploying the tool within any organization's infrastructure.
Se destaca la optimización del SIEM Wazuh como una «herramienta robusta» mediante la integración de otras soluciones de código abierto que añaden capacidades adicionales de ciberseguridad. Esta estrategia enfatiza la importancia de mejorar sistemas existentes en lugar de crear nuevos, lo que contribuye a una solución más sostenible a largo plazo.
The importance of training the cybersecurity team for proactive detection and response is stressed.
