Custom risk indicators

The user risk indicators that Citrix Analytics detects by default are based on machine learning algorithms. Citrix Analytics now allows you to create custom risk indicators. You can define conditions based on the user events and create a custom risk indicator. If the events match the defined criteria, Citrix Analytics triggers the custom risk indicator and displays it on the user’s risk timeline.

You can create custom risk indicators on the following data sources:

  • Citrix Access Control
  • Citrix Content Collaboration
  • Citrix Gateway
  • Citrix Virtual Apps and Desktops

Custom risk indicators page

The Custom Risk Indicators page provides insights into all the custom risk indicators generated for a user, severity, data source, number of policies, status, and the last modified date and time of the indicator. To create a custom risk indicator, see Creating a custom risk indicator.

When you select the risk indicator, you are redirected to the Modify Risk Indicator page. For more information, see Modifying a custom risk indicator.

Analyzing a custom risk indicator

Consider the user whose action triggered a custom risk indicator that you defined. When this behavior is detected, Citrix Analytics generates a custom risk indicator for the respective user.

When you select the custom risk indicator on the user’s risk timeline, the right pane displays the following information:

  • Defined Condition(s): Shows a summary of the conditions that you define while creating a custom risk indicator.

  • Description: Provides a summary of the description you provide while creating the custom risk indicator. If no description is provided while creating the custom risk indicator, this section reflects None.

  • Trigger Frequency: Displays the option that you select in the Advanced options section while creating the custom risk indicator.
