Anti-DDoS supports watermark protection for the messages sent by the application end. Within the range of the UDP and TCP message ports configured, the application end and Anti-DDoS share the same watermark algorithm and key. After the configuration is completed, every message sent from the client will be embedded with the watermark while attack messages will not, so that the attack messages can be identified and discarded. Watermark protection can effectively and comprehensively defend against layer-4 CC attacks, such as analog business packet attacks and replay attacks.
You have purchased an Anti-DDoS Advanced (Global Enterprise Edition) instance and set the object to protect.
