What Security Capabilities Does CDN Provide?

  • By adding your domain name to Huawei Cloud CDN, you can have your origin IP addresses hidden to prevent origin servers from being exposed to attackers.
  • If CDN PoPs fail to provide services due to heavy attack traffic, CDN will temporarily ban the attacked domain name, change its status to Disabled, and disable the acceleration service for it. The domain name cannot be accessed but its configuration is retained (within the retention period).
  • CDN supports referer validation, IP address access control lists (ACLs), and token authentication. For details, see Access Control.
  • You can enable Edge Security Service (ESA) to protect your domain names.
