Get started on the Splunk UBA home page

To begin using Splunk User Behavior Analytics (UBA), login to the Splunk UBA web interface on the management server in your deployment.

Log in to the Splunk UBA web interface

In a supported web browser, type in the IP address or host name of your Splunk UBA management server to access the Splunk UBA Web interface. If you are logging in for the first time, use the default Splunk UBA credentials of admin for the username and changeme as the password. After you log in, perform the tasks in Secure the default account after installing Splunk UBA in Install and Upgrade Splunk User Behavior Analytics.

The IP address you specify may differ slightly depending on your operating system environment. For example, in Linux environments, you specify the IP address of the Splunk UBA management server, but for VMware or Amazon Web Services (AWS) environments, you specify the public IP address to access Splunk UBA. See the end of the installation instructions for your specific environment in Install Splunk User Behavior Analytics in Install and Upgrade Splunk User Behavior Analytics.

Filter the scope of anomalies and threats

Click Scope on the menu bar to filter the anomalies and threats that are displayed in Splunk UBA. By default, anomalies and threats for all time are displayed. You can select one of the options to view anomalies and threats for a specific period of time. Any Date is used as the default.

Entity scoring for users, devices, and apps is affected by adjusting this filter. Entity scoring occurs automatically on a daily basis.

Scope Selected in Splunk UBA	How the Scope Affects Entity Scoring
Any Date (Default)	Entity scoring is based on anomalies and threats from the past 2 months. This window of time can be customized by adjusting the entity.score.lookbackWindowMonths property in the /etc/caspida/local/conf/uba-site.properties file.
Last 12 Months	Entity scoring is based on anomalies and threats from the past 2 months. This window of time can be customized by adjusting the entity.score.lookbackWindowMonths property in the /etc/caspida/local/conf/uba-site.properties file.
Last 30 Days	Entity scoring is based on anomalies and threats from the past 30 days.
Last 7 Days	Entity scoring is based on anomalies and threats from the past 7 days.

Entity scoring occurs in real time when new anomalies are raised, or when existing anomalies are placed in the trash, permanently deleted, or restored.

Some anomaly actions can cause real-time entity scoring adjustments and it may take up to 24 hours before the updated scores are reflected in Splunk UBA.
