    DDoS Edge Defender supports precise protection for connected web applications. With the precise protection, 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 the requests matched the conditions, you can configure CAPTCHA to verify the requesters or a policy to automatically drop the packets. Precise protection is available for policy customization in various use cases to precisely defend against CC attacks.

    The match conditions define the request characteristics to be checked, i.e., the attribute characteristics of the HTTP field in a request. Precise protection supports checking the HTTP fields below:

    Field Description Logic
    URI URL address of the access request Equal to; Include; Exclude
    UA Information including identifier of the client browser that initiates the access request Equal to; Include; Exclude
    Cookie Cookie information in the access request Equal to; Include; Exclude
