Overview

You can configure referer validation, IP address access control lists (ACLs), User-Agent ACLs, token authentication, remote authentication, and IP access frequency to identify and filter out unauthorized users and improve CDN security.

You can modify access control settings of a domain name that is in the Enabled or Configuring state and is not locked or banned by CDN.
