What type of data does QRadar primarily collect?

QRadar primarily collects security events and network flows as it is designed to serve as a security information and event management (SIEM) system. Its main purpose is to aggregate, analyze, and correlate security-related data from various sources such as firewalls, intrusion detection systems, and other security appliances. Security events, which include logs generated by security devices and applications, are crucial for identifying potential threats and incidents.

Network flows also play a vital role in understanding the traffic patterns within a network, helping to detect anomalies that may indicate malicious activities. By working with both types of data, QRadar can provide comprehensive visibility into an organization's security posture, enabling effective threat detection, incident response, and compliance reporting. This ability to collect, analyze, and correlate a diverse range of security-related data is what positions QRadar as a critical tool in cybersecurity management.
