Web Application Firewall：ModifyProtectionModuleRule

Usage notes

You can call the ModifyProtectionModuleRule operation to modify a rule of a specific WAF protection module. The protection modules include web intrusion prevention, data security, advanced protection, bot management, access control or throttling, and website whitelist. You can set the DefenseType parameter to specify the protection module. For more information about the values of this parameter, see the description of the DefenseType parameter.

QPS limits

You can call this operation up to 10 times per second per account. If the number of the calls per second exceeds the limit, throttling is triggered. As a result, your business may be affected. We recommend that you take note of the limit when you call this operation.

• If the DefenseType parameter is set to whitelist, the value of the Rule parameter consists of the following parameters:
  • name: the name of the rule. This parameter is required. Data type: string.
  • tags: the protection module that does not check requests. This parameter is required. Data type: array. The values of the tags parameter vary based on the types of the whitelist.

    Note The values of the tags parameter can contain only the values that are listed in a specific whitelist. For example, the values of the tags parameter cannot contain both regular and cc. This is because regular belongs to the whitelist for the web intrusion prevention module and cc belongs to the whitelist for the access control or throttling module.
    • To configure the global whitelist, set the tags parameter to the following value:
      • waf: Requests bypass all protection modules.
    • To configure the whitelist for the web intrusion prevention module, set the tags parameter to one or more of the following values:
      • regular: Requests bypass the protection rules engine module. Requests bypass all protection rules.
      • regular_rule: Requests bypass specific rules of the protection rules engine module. If you set the tags parameter to the value, you must configure the regularRules parameter to specify the IDs of the rules.
      • regular_type: Requests bypass specific types of the rules of the protection rules engine module. If you set the tags parameter to the value, you must configure the regularRules parameter to specify the types of the rules.
      • deeplearning: Requests bypass the deep learning engine module.
    • To configure the whitelist for the access control or throttling module, set the tags parameter to one or more of the following values:
      • cc: Requests bypass the HTTP flood protection module.
      • customrule: Requests bypass custom protection policies.
      • blacklist: Requests bypass the IP address blacklist module.
      • antiscan: Requests bypass the scan protection module.
    • To configure the whitelist for the data security module, set the tags parameter to one or more of the following values:
      • dlp: Requests bypass the data leakage prevention module.
      • tamperproof: Requests bypass the website tamper-proofing module.
      • account: Requests bypass the account security module.
    • To configure the whitelist for the bot management module, set the tags parameter to one or more of the following values:
      • bot_intelligence: Requests bypass the bot threat intelligence module.
      • bot_algorithm: Requests bypass the typical bot behavior identification module.
      • bot_wxbb: Requests bypass the app protection module.
      • antifraud: Requests bypass the data risk control module.
  • antifraud: Requests bypass the data risk control module. If the value of the tags parameter contains regular_rule, the regularRules parameter is required. You can view the IDs of the rules when you create a rule group. To create a rule group, go to the WAF console and click Protection Rule Group. On the page that appears, click Create Rule Group. For more information, see Customize protection rule groups.

        {
            "name": "test",
            "tags": ["cc","customrule"],
