Which feature enables QRadar to track security metrics over time?

The ability of QRadar to track security metrics over time is primarily facilitated by dashboard visualization. This feature allows users to create and customize graphical representations of various security events, incidents, and metrics, which can be monitored in real-time or over specific time frames. Through the use of dashboards, security teams can visualize trends, track performance indicators, and analyze historical data effectively, providing insights that help in understanding the evolution of security threats and the overall security posture of the organization.

While event correlation, log analysis, and flow aggregation are important functionalities within QRadar, they do not inherently focus on presenting data in a way that allows for the ongoing tracking of metrics over time. Event correlation helps to identify relationships and patterns between security events, log analysis involves the examination of log data to uncover relevant information, and flow aggregation pertains to summarizing network flows for analysis. However, it is the dashboard visualization feature that serves as the comprehensive tool for continuously monitoring and reporting security metrics in an easily digestible format.
