Adaptive User Segmentation

Illumio's Adaptive User Segmentation (AUS) allows you to leverage Microsoft Active Directory User Groups to control access to computing resources in your organization. With this feature, you can create user groups in the PCE that map directly to your Active Directory Groups.

Overview of Adaptive User Segmentation

You can then create rules using these groups to control outbound access on specific workloads, such as a VDI desktop, based on the user's group membership logged in to that workload.

For example, you may want to restrict access to the ERP application to only employees in the Sales user group, but not to users in the HR department. You may wish to allow HR users to access only HR applications, but not all internal resources.

If you have a Windows workload that controls access to other resources in your network, such as a VDI desktop with the VEN installed, you can add both the VDI desktop workload and Active Directory User Groups to the rule. Writing this type of rule allows user access only to the resources that are explicitly allowed by the rules.

Add Active Directory User Groups
  1. From the PCE web console menu, choose Policy Objects > User Groups.

  2. On the User Groups page, click Add.

  3. In the User Group page, enter a name, system identifier (SID), and description for the Active Directory Group.

  4. Click Save.

    The new Active Directory Group appears in the User Groups list. You can now use the user group in a policy to control access to specific workloads.

Note

A maximum of 100 User Groups can be displayed.
