What is the primary function of Security Information and Event Management (SIEM) Systems?

The primary function of Security Information and Event Management (SIEM) systems is to consolidate log files into a centralized database. This centralization allows organizations to collect, store, and analyze security data from various sources, such as servers, network devices, and applications. By aggregating this information, SIEM systems facilitate better visibility into security events across the entire network, enabling security teams to identify patterns, detect anomalies, and respond to potential threats in a more efficient manner.

SIEM systems also perform correlation of events, helping to identify advanced threats that may not be evident from any single log entry. This enhanced capability can significantly improve an organization’s ability to manage and respond to incidents, keeping the overall security posture stronger.
