Wazuh is an open-source platform for continuous security monitoring. It brings threat detection, vulnerability detection, file-integrity monitoring, and compliance analysis into one view, helping teams turn activity across their systems into findings they can investigate. section 8.2
Agents on endpoints send information to a central Wazuh server for analysis and display in a dashboard. Wazuh can run on one server or scale across multiple nodes. Its rule-based engine monitors logs, network traffic, and file integrity, then alerts on suspicious activity. section 8.2
Use the findings according to the decision they support:
- Investigate alerts about unusual login attempts, unauthorized file changes, or unexpected network connections before they become larger incidents. section 8.2
- Prioritize corrective action using detected vulnerabilities and their severity. section 8.2
- Review compliance reports and dashboards against requirements such as PCI DSS, GDPR, and HIPAA. section 8.2
From alert to incident analysis
Suppose Wazuh flags an unauthorized change to a critical file alongside unusual login attempts. Collect the relevant alerts, logs, and network data; correlate them for indicators of compromise; then reconstruct the event timeline and assess which systems or data were affected. The alert starts the investigation—it does not, by itself, establish the incident’s cause or business impact. section 8.2 section 9.5
Set alerts and thresholds against the organization’s risk tolerance, and pair monitoring with clear reporting and response. Wazuh can integrate with the ELK Stack for visualization, but open-source deployments can demand substantial configuration and maintenance. Judge success by whether findings support timely, prioritized action—not by alert volume alone. section 10.2.5 section 3.5.1 section 8.8
