AWS::WAFv2::WebACL ManagedRuleGroupStatement

A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement.

You cannot nest a ManagedRuleGroupStatement, for example for use inside a NotStatement or OrStatement. It can only be referenced as a top-level statement within a rule.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "ExcludedRules" : [ ExcludedRule, ... ],
  "ManagedRuleGroupConfigs" : [ ManagedRuleGroupConfig, ... ],
  "Name" : String,
  "ScopeDownStatement" : Statement,
  "VendorName" : String,
  "Version" : String
}

YAML

  ExcludedRules: 
    - ExcludedRule
  ManagedRuleGroupConfigs: 
    - ManagedRuleGroupConfig
  Name: String
  ScopeDownStatement: 
    Statement
  VendorName: String
  Version: String

Properties

ExcludedRules

The rules in the referenced rule group whose actions are set to Count. When you exclude a rule, AWS WAF evaluates it exactly as it would if the rule action setting were Count. This is a useful option for testing the rules in a rule group without modifying how they handle your web traffic.

Required: No

Type: List of ExcludedRule

Maximum: 100

Update requires: No interruption

ManagedRuleGroupConfigs

Additional information that's used by a managed rule group. Most managed rule groups don't require this.

Use this for the account takeover prevention managed rule group AWSManagedRulesATPRuleSet, to provide information about the sign-in page of your application.

You can provide multiple individual ManagedRuleGroupConfig objects for any rule group configuration, for example UsernameField and PasswordField. The configuration that you provide depends on the needs of the managed rule group. For the ATP managed rule group, you provide the following individual configuration objects: LoginPath, PasswordField, PayloadType and UsernameField.

Required: No

Type: List of ManagedRuleGroupConfig

Update requires: No interruption

Name

The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.

Required: Yes

Type: String

Minimum: 1

Maximum: 128

Pattern: ^[\w\-]+$

Update requires: No interruption

ScopeDownStatement

An optional nested statement that narrows the scope of the web requests that are evaluated by the managed rule group. Requests are only evaluated by the rule group if they match the scope-down statement. You can use any nestable Statement in the scope-down statement, and you can nest statements at any level, the same as you can for a rule statement.

Required: No

Type: Statement

Update requires: No interruption

VendorName

The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.

Required: Yes

Type: String

Minimum: 1

Maximum: 128

Pattern: .*\S.*

Update requires: No interruption

Version

The version of the managed rule group to use. If you specify this, the version setting is fixed until you change it. If you don't specify this, AWS WAF uses the vendor's default version, and then keeps the version at the vendor's default when the vendor updates the managed rule group settings.

Required: No

Type: String

Minimum: 1

Maximum: 64

Pattern: ^[\w#:\.\-/]+$

Update requires: No interruption
