What is a "reference set" in QRadar?

A "reference set" in QRadar is defined as a collection of related values that can be utilized in the creation of rules and builds within the SIEM system. This allows security analysts to manage and use data more efficiently by grouping similar pieces of information together. Reference sets can include IP addresses, user IDs, or other specific data points that might need to be referenced in correlation rules. By leveraging reference sets, users can create more sophisticated detection strategies and respond to potential threats with greater accuracy.

Utilizing reference sets is beneficial for enhancing performance and maintaining consistency in how data is evaluated against your security policies. This flexibility is part of what makes QRadar a powerful tool for security information and event management, as it allows organizations to customize their detection and response measures based on the specific context of their operational environment.
