How Do I Check If CDN Is Being Maliciously Used?

If your site is attacked or has malicious traffic coming, there may be sudden traffic spikes that result in a bill higher than your normal expenditures. This section describes the potential risks and solutions.

• Risks

  Attacks and malicious traffic generate excessive bandwidth usage, and you need to pay significantly more than you usually do.

• Solutions
  1. Configure access control (including referer validation, IP address ACL, and token authentication) for domain names to avoid unnecessary traffic or bandwidth consumption. For details, see Access Control.
  2. Enable balance alert. If the available balance in your account is lower than the specified amount, the system will send you an SMS alert.
     

     To ensure data integrity and accuracy of bills, a bill is usually generated after a billing cycle ends. Therefore, the bill time is later than the time when resources are consumed, and resource consumption cannot be reflected in real time through bills. This is due to the distributed architecture of CDN PoPs. This billing method is widely used.
