What is "Log Aggregation" in QRadar?

Log aggregation in QRadar refers to the process of collecting log data in a centralized location. This functionality is crucial for effective security information and event management (SIEM) because it allows for streamlined data management and analysis. By gathering logs from various sources, such as network devices, servers, applications, and endpoints, QRadar enables organizations to have a comprehensive view of their security posture.

Centralized log collection not only aids in real-time monitoring but also facilitates historical analysis and compliance reporting. It simplifies the process of identifying patterns, anomalies, and potential security incidents, as all relevant logs are housed in one place, making it easier for analysts to investigate and respond to threats.

This approach contrasts with analyzing logs for real-time threat detection, distributing logs to various storage systems, or filtering out irrelevant log entries, which are all elements of broader log management but do not capture the essence of log aggregation as a primary function.
