Examples

Define Geographic Constraints

The following example defines a set of GeoMatchConstraints for a web access control list (ACL) rule.

JSON

"MyGeoConstraints": {
  "Type": "AWS::WAFRegional::GeoMatchSet",
  "Properties": {
    "Name": "GeoMatchSet for restricted countries",
    "GeoMatchConstraints": [
      {
        "Type" : "Country",
        "Value" : "AE"
      },
      {
        "Type" : "Country",
        "Value" : "ZW"
      }
    ]
  }      
}

YAML

MyGeoConstraints: 
  Type: "AWS::WAFRegional::GeoMatchSet"
  Properties: 
    Name: "GeoMatchSet for restricted countries"
    GeoMatchConstraints: 
      - 
        Type: "Country"
        Value: "AE"
      - 
        Type: "Country"
        Value: "AE"

Associate a GeoMatchSet with a Web ACL Rule

The following example associates the MyGeoConstraints with a web ACL rule.

JSON

"MyGeoMatchRule" : {
  "Type": "AWS::WAFRegional::Rule",
  "Properties": {
    "Name": "MyGeoMatchRule",
    "MetricName" : "MyGeoMatchRule",
    "Predicates": [
      {
        "DataId" : {  "Ref" : "MyGeoConstraints" },
        "Negated" : false,
        "Type" : "GeoMatch"
      }
    ]
  }      
}

YAML

MyGeoMatchRule: 
  Type: "AWS::WAFRegional::Rule"
  Properties: 
    Name: "MyGeoMatchRule"
    MetricName: "MyGeoMatchRule"
    Predicates: 
      - 
        DataId: 
          Ref: "MyGeoConstraints"
        Negated: false
        Type: "GeoMatch"

Create a Web ACL

The following example associates the MyGeoMatchRule rule with a web ACL. The web ACL allows requests that originate from all countries except for those that are defined in the MyGeoMatchRule.

JSON

"MyWebACL": {
  "Type": "AWS::WAFRegional::WebACL",
  "Properties": {
    "Name": "WebACL to block restricted countries",
    "DefaultAction": {
      "Type": "ALLOW"
    },
    "MetricName" : "MyWebACL",
    "Rules": [
      {
        "Action" : {
          "Type" : "BLOCK"
        },
        "Priority" : 1,
        "RuleId" : { "Ref" : "MyGeoMatchRule" }
      }
    ]
  }      
}

YAML

MyWebACL: 
  Type: "AWS::WAFRegional::WebACL"
  Properties: 
    Name: "WebACL to block restricted countries"
    DefaultAction: 
      Type: "ALLOW"
    MetricName: "MyWebACL"
    Rules: 
      - 
        Action: 
          Type: "BLOCK"
        Priority: 1
        RuleId: 
          Ref: "MyGeoMatchRule"
