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.
- IP addresses belong to carriers and change irregularly. Although Huawei Cloud periodically updates the IP address library, the update may be delayed. As a result, some access control functions may occasionally block or allow requests, or client requests may not be scheduled to the optimal PoP.
