Enabling Watermark Protection
Last updated: 2019-01-14 15:50:49PDF
You can efficiently and comprehensively protect against layer 4 CC attacks such as masquerading and replay attacks by accessing watermark protection. By sharing the watermark algorithm and key between the business side and the Aegis protection system, watermark protection embeds a watermark in every message sent by the client. As the attack messages have no watermark, the protection system can easily identify and discard them. For more information on the configuration, see Custom Advanced Security Policy.
How to Enable

Go to the Aegis Anti-DDoS Console, click Business Domain Name List* in the left pane, and click **Enable watermark.
