Use Cases
Anti-DDoS Advanced supports precise protection for connected web businesses. With precise protection enabled, you can configure protection policies combining multiple conditions of common HTTP fields, such as uri, ua, cookie, referer, and accept to screen access requests. For requests that match the conditions, you can configure CAPTCHA to verify the requesters or a policy to automatically drop or allow the requests. Precise protection is available for policy customization in various use cases to precisely defend against CC attacks.
Match conditions define the request characteristics to be verified, that is, the attribute characteristics of HTTP fields in a request. Precise protection supports verifying the following HTTP fields:
Field | Description | Logic |
uri | URI of an access request | Equal to, include, and exclude |
ua | Identifier and other information of the client browser that initiates an access request | Equal to, include, and exclude |
cookie | Cookie information in an access request | Equal to, include, and exclude |
referer | Source website of an access request, from which the access request is redirected | Equal to, include, and exclude |
accept | Data type to be received by the client that initiates the access request | Equal to, include, and exclude |
script | Source web address of the access request | Equal to and not equal to |
Directions
1. Log in to the new Anti-DDoS console and click CC Protection on the left sidebar.
2. Select a domain name from the left list.
3. In the Precise protection section, click Set.
