An information barrier must exist before you can add segments to it. Segments contain one or more managed users, and no managed user can exist in more than one segment.
- Go to Admin Console > Shield.
- Click the Information Barrier tab.
- Click Edit. (If you do not see an information barrier, create one first.)
- Click Add Segment. (You can add up to 10 segments. If the information barrier contains 10 segments, the Add Segment link will not be available.)
- Enter a segment name and an optional description. (A description is recommended to help you understand the segment's context and purpose.)
- Click Save.
- Click Add Users in the segment you just created.
- Click Select File to select and upload a list of users from a CSV (comma-separated values) file. If you do not have a file with a list of users ready, click Download blank, pre-formatted CSV template and add users to that file. As the file is being uploaded, it is being checked for conflicts with any other segments. (Segments cannot contain users who exists in other segments.)
- Select the CSV file from your file system and click Open.
- Review the results of the conflict check. If there are no conflicts, or if you are satisfied with the conflict resolution, click Save. Otherwise, click Start Over to upload a new list of users.
