Configuring a Traffic Identifier for a Known Attack Source

WAF allows you to configure traffic identifiers by IP address, session, or user tag to block possibly malicious requests from known attack sources based on IP address, Cookie, or Params.

If you have enabled enterprise projects, ensure that you have all operation permissions for the project where your WAF instance locates. Then, you can select the project from the Enterprise Project drop-down list and configure known attack source traffic identifiers for the domain names.

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 Layer-7 proxy 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 under Security & Compliance.
  4. In the navigation pane on the left, 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.

    Tag

    Description

    Example Value

    IP Tag

    HTTP request header field of the original client IP address.

    Ensure that the protected website has a layer-7 proxy configured in front of WAF and that Proxy Configured under the website basic information settings is set to Layer-7 proxy for this parameter to take effect.

    This field is used to store the real IP address of the client. You can customize the field name and configure multiple fields (separated by commas). After the configuration, WAF preferentially reads the configured field to obtain the real IP address of the client. If multiple fields are configured, WAF reads the IP address from left to right.
    NOTICE:
    • If you want to use a TCP connection IP address as the client IP address, set IP Tag to $remote_addr.
    • If WAF does not obtain the real IP address of a client from fields you configure, WAF reads the cdn-src-ip, x-real-ip, x-forwarded-for, and $remote_addr fields in sequence to read the client IP address.

    X-Forwarded-For

    Session Tag

    This tag is used to block possibly malicious requests based on the cookie attributes of an attack source. Configure this parameter to block requests based on cookie attributes.

    jssessionid

    User Tag

    This tag is used to block possibly malicious requests based on the Params attribute of an attack source. Configure this parameter to block requests based on the Params attributes.

    name

  7. Click Confirm.
