Configuring a Traffic Identifier for a Known Attack Source

Prerequisites

The website to be protected has been added to WAF.

Constraints

• If the IP address tag is configured, ensure that the protected website has a layer-7 proxy configured in front of WAF and that Proxy Configured is set to Yes for the protected website.

  If the IP address tag is not configured, WAF identifies the client IP address by default.

• Before enabling Cookie- or Params-based known attack source rules, configure a session or user tag for the corresponding website domain name.

Procedure

1. Log in to the management console.
2. Click in the upper left corner of the management console and select a region or project.
3. Click in the upper left corner and choose Web Application Firewall (Dedicated) under Security.
4. In the navigation pane, choose Website Settings.
5. In the Domain Name column, click the domain name of the target website to go to the basic information page.
6. In the Traffic Identifier area, click next to IP Tag, Session Tag, or User Tag to configure a traffic identifier by referring to Table 1. Figure 1 shows an example.
