In QRadar, how are alerts typically scored for severity?

In QRadar, alerts are typically scored for severity through a scoring rubric that assesses threat levels. This method involves evaluating various factors related to the detected security incident, including the nature of the threat, its potential impact, the behavior that led to the alert, and the context within which it occurred. By using a scoring rubric, QRadar can assign severity levels that reflect the urgency and importance of the alert, allowing security teams to prioritize their response efforts effectively. This system is designed to ensure that alerts that pose a greater risk or indicate a more severe threat are escalated or acted upon more swiftly, thereby enhancing the overall security posture of the organization.

The other options do not accurately represent how QRadar processes alerts. While the number of devices affected could influence the context of an alert, it is not a primary basis for scoring severity. Similarly, predefined security policies might inform alerts but do not directly determine their severity scoring. User feedback may contribute to refining detection and response processes over time, but it does not play a role in the initial scoring of alerts as determined by the system's rubric.
