This guide helps you prevent extra costs from extensive bandwidth and traffic caused by attacks and hotlinking. Note that such costs cannot be waived or refunded.
Access Control
Enable access control (free of charge) for your domain names in the console.
Item
Description
Hotlink protection
Configure a policy based on the referer field in the HTTP request header
IP blocklist/allowlist
Set up a policy based on requester IPs
IP access limit
Apply upper limits on the number of access requests/second/node from a client IP, which can help defend against high-frequency CC attacks and hotlinking.
Authentication configuration
Require the client to calculate the signature as configured and add it to the request. The CDN node allows the request only when the signature is authenticated.
UA blocklist/allowlist
Check the User-Agent of the HTTP request header and allow/reject requests according to the configured blocklist/allowlist.
Downstream speed limit
Control the CDN downstream bandwidth by setting the maximum throughput speed of a URL on the server.
Traffic Management
Set up policies for traffic and bandwidth control, monitor the traffic and bandwidth and get alerts in time.
Item
Description
Usage limit
You can set a traffic/bandwidth usage limit for your domain name. When the traffic/bandwidth generated within a 5-minute period exceeds the limit, the CDN service will be suspended, returning 404 to all incoming requests.
Cloud Monitor
Cloud Monitor helps monitor your CDN domain names and traffic usage. It also supports alerting via SMS, email and WeChat if the usage threshold is reached, allowing you to spot potential risks in a timely manner.
Traffic packs
If you choose traffic-based billing, set the alert policies in Traffic Pack Management. You will be notified when the remaining traffic quota goes below the threshold.
