What is the primary purpose of performing queries in a SIEM tool?

The primary purpose of performing queries in a Security Information and Event Management (SIEM) tool is to investigate events and generate actionable reports. SIEM tools aggregate and analyze security data from various sources, such as logs from servers, applications, and network devices. By conducting queries on the collected data, security analysts can uncover patterns, detect anomalies, and understand the context of security incidents.

This ability to dissect and analyze data is essential for quickly responding to potential threats, providing insights for compliance reporting, and helping teams make informed decisions based on comprehensive data analysis. Actionable reports generated from these queries help in identifying vulnerabilities, potential breaches, and areas where security posture can be improved, ultimately contributing to a stronger security framework.

In contrast, controlling user access rights is more related to identity and access management, while automating patch management processes focuses on keeping software up to date to mitigate vulnerabilities. Monitoring network bandwidth usage pertains to traffic analysis rather than security event management. Therefore, none of these options align with the core functionality of SIEM tools as effectively as investigating events and generating actionable reports does.
