Explanation
Detailed information about identities, such as user names, email addresses, phone numbers, and roles, is stored in the Identity Lookup CSV file in Splunk Enterprise Security. The Identity Lookup CSV file is a lookup file that contains the identity data that is collected and extracted from various data sources, such as Active Directory, LDAP, or custom identity lists. The Identity Lookup CSV file is used to enrich events with identity information and generate notable events based on identity correlation searches. You can view and manage the Identity Lookup CSV file using the Asset and Identity Management page in Splunk Enterprise Security.
