Defining the allowlist

As an administrator, you can restrict access to CES through approved hosts only. This adds a layer of security against host header poisoning attacks. You can manage the approved hosts in a table. 

On the Allowlist tab, you can view the hosts. Some hosts appear by default and are tied to the machine on which CES is installed. These pre-approved hosts cannot be deleted and appear grayed-out in the table.
