Audit user activity in Splunk UBA

You can audit user activity in Splunk UBA by reviewing the audit logs in Splunk UBA or by sending audit logs to the Splunk platform for analysis.

User activity logged by Splunk UBA

Audit logs contain the name of the action performed, the type of the action performed, the username of the user performing the action, and the time of the action. In addition, if the action performed affects an entity such as a user or device, Splunk UBA logs the entity type, entity ID, and the URL for the affected entity details page. To see more details about an entity, search the entity ID in the table relevant to the entity type. For example, search an entity ID for a device in the Devices table.

By default, Splunk UBA retains three months of user activity audit logs.

Audit log example

For example, audit logs for the user jgonzalez downloading diagnostic data and then viewing the device details page for a device look as follows:

Action Name Details Username Time

retentionPeriodInDays: 2
jgonzalez Jun 13, 2017 2:14 PM
View Device Details acme-61669202 jgonzalez Jun 13, 2017 5:33 PM

The device name is a link to the device details page.

Filter by time, action, username, or entity type to reduce the scope of the audit logs for review. For example, you can examine the activity of a specific user over a period of time, identify the users that performed a sensitive action in a period of time, locate the user that interacted with a specific threat in Splunk UBA, or show all activity for a narrow period of time.

Send audit logs to the Splunk platform for analysis
