What does the “Flow” data in QRadar represent?

The "Flow" data in QRadar represents network traffic information that summarizes behaviors across the network. This type of data is crucial because it allows security analysts to understand the flow of data packets between devices, analyze communication patterns, and identify anomalies indicative of potential security threats.

Flow data includes details such as the source and destination IP addresses, the ports being used, the protocols involved, and the volume of data transferred. By aggregating this information, QRadar enables users to see how users and systems interact over the network, which can aid in detecting unusual activity or performance issues.

Understanding network behaviors through flow data is vital for spotting potential intrusions, unauthorized access attempts, or unusual patterns that may warrant further investigation. This summary perspective of traffic patterns helps organizations maintain a secure and efficient network environment.
