What does a Security Information and Event Management (SIEM) system primarily do?

• A. Provides cloud storage solutions
• B. Performs software updates
• C. Collects and analyzes security incidents
• D. Manages company email accounts

Answer: (C)

A Security Information and Event Management (SIEM) system is designed to collect, analyze, and correlate security data from across an organization’s network and various systems. Its primary function is to provide real-time visibility into security incidents by gathering logs from servers, devices, applications, and other data sources. SIEM solutions help in identifying potential security threats by analyzing patterns and anomalies in the collected data, enabling organizations to respond proactively to incidents and improve overall security posture. The focus of a SIEM system is on enhancing security through the aggregation and correlation of log data, which helps in detecting not only individual security events but also understanding the context and potential impact of those events on the organization. This capability is essential for maintaining effective security monitoring and compliance with regulatory standards. The other choices relate to functions that are not aligned with the core purpose of a SIEM. For instance, cloud storage solutions pertain to data storage and management rather than security incident monitoring. Software updates are about maintaining system integrity and performance and do not directly involve security incident analysis. Managing email accounts is an administrative function unrelated to the detection or analysis of security threats.
