Reference sets overview
Use reference sets in IBM QRadar to store data in a simple list format.
You can populate the reference set with external data, such as indicators of compromise (IOCs), or you can use it to store business data, such as IP addresses and user names, that is collected from events and flows that occur on your network.
A reference set contains unique values that you can use in searches, filters, rule test conditions, and rule responses. Use rules to test whether a reference set contains a data element, or configure the rule response to add data to a reference set. For example, you can create a rule that detects when an employee accesses a prohibited website, and configure the rule response to add the employee's IP address or user name to a reference set.
For more information about configuring rule responses to add data to a reference set, see the IBM QRadar User Guide.
Reference sets are the only type of reference data collection that you can manage in QRadar. You can also use the command-line and the Restful API documentation interface to manage reference sets.
