What are the two main types of data that QRadar analyzes?

QRadar primarily analyzes two main types of data: event data and flow data.

Event data refers to the individual logs generated by various security devices, applications, and systems. These logs encompass security events, such as authentication attempts, network connections, and system alerts. QRadar collects, aggregates, and analyzes this event data to identify patterns or anomalies that could indicate security incidents.

Flow data, on the other hand, represents the network traffic information that details the communication between different network entities, such as servers, endpoints, and applications. It includes details about the packets sent over the network, including attributes like source/destination IP addresses, ports used, and protocols. Analyzing flow data allows QRadar to detect suspicious activities, track bandwidth usage, and monitor overall network performance.

The combination of event and flow data provides a comprehensive view of the security posture of an organization, enabling effective threat detection and incident response.
