Implements IConstruct, IDependable, IInspectable, ITaggableV2

Enables AWS Shield Advanced for a specific AWS resource.

The resource can be an Amazon CloudFront distribution, Amazon Route 53 hosted zone, AWS Global Accelerator standard accelerator, Elastic IP Address, Application Load Balancer, or a Classic Load Balancer. You can protect Amazon EC2 instances and Network Load Balancers by association with protected Amazon EC2 Elastic IP addresses.

Configure a single AWS::Shield::Protection

Use this protection to protect a single resource at a time.

To configure this Shield Advanced protection through AWS CloudFormation , you must be subscribed to Shield Advanced . You can subscribe through the Shield Advanced console and through the APIs. For more information, see Subscribe to AWS Shield Advanced .

See example templates for Shield Advanced in AWS CloudFormation at aws-samples/aws-shield-advanced-examples .

Configure Shield Advanced using AWS CloudFormation and AWS Firewall Manager

You might be able to use Firewall Manager with AWS CloudFormation to configure Shield Advanced across multiple accounts and protected resources. To do this, your accounts must be part of an organization in AWS Organizations . You can use Firewall Manager to configure Shield Advanced protections for any resource types except for Amazon Route 53 or AWS Global Accelerator .

For an example of this, see the one-click configuration guidance published by the AWS technical community at One-click deployment of Shield Advanced .

Configure multiple protections through the Shield Advanced console

You can add protection to multiple resources at once through the Shield Advanced console . For more information see Getting Started with AWS Shield Advanced and Managing resource protections in AWS Shield Advanced .

Initializer

new CfnProtection(scope: Construct, id: string, props: CfnProtectionProps)

Parameters

• scope Construct — Scope in which this resource is defined.
• id string — Construct identifier for this resource (unique in its scope).
• props CfnProtectionProps — Resource properties.

Construct Props

Name	Type	Description
name	string	The name of the protection. For example, My CloudFront distributions .
resourceArn	string	The ARN (Amazon Resource Name) of the AWS resource that is protected.
applicationLayerAutomaticResponseConfiguration?	IResolvable | ApplicationLayerAutomaticResponseConfigurationProperty	The automatic application layer DDoS mitigation settings for the protection.
healthCheckArns?	string[]	The ARN (Amazon Resource Name) of the health check to associate with the protection.
tags?	CfnTag[]	Key:value pairs associated with an AWS resource.

---

name

Type: string

The name of the protection. For example, My CloudFront distributions .

If you change the name of an existing protection, Shield Advanced deletes the protection and replaces it with a new one. While this is happening, the protection isn't available on the AWS resource.

---

resourceArn

Type: string

The ARN (Amazon Resource Name) of the AWS resource that is protected.

---

applicationLayerAutomaticResponseConfiguration?

Type: IResolvable | ApplicationLayerAutomaticResponseConfigurationProperty (optional)

The automatic application layer DDoS mitigation settings for the protection.

This configuration determines whether Shield Advanced automatically manages rules in the web ACL in order to respond to application layer events that Shield Advanced determines to be DDoS attacks.

If you use AWS CloudFormation to manage the web ACLs that you use with Shield Advanced automatic mitigation, see the additional guidance about web ACL management in the AWS::WAFv2::WebACL resource description.

---

healthCheckArns?

Type: string[] (optional)

The ARN (Amazon Resource Name) of the health check to associate with the protection.

Health-based detection provides improved responsiveness and accuracy in attack detection and mitigation.

You can use this option with any resource type except for Route 53 hosted zones.

For more information, see Configuring health-based detection using health checks in the AWS Shield Advanced Developer Guide .

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

• path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).

---

addDependency(target)

public addDependency(target: CfnResource): void

Parameters

• target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

---

addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

• target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

---

addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

• key string
• value any

Add a value to the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)

---

addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

• path string — - The path of the property, you can use dot notation to override values in complex types.
• value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

---

addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

• propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.

---

addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

• propertyPath string — The path of the property.
• value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

---

applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

• policy RemovalPolicy
• options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

---

getAtt(attributeName, typeHint?)

public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference

Parameters

• attributeName string — The name of the attribute.
• typeHint ResolutionTypeHint

Returns

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

---

getMetadata(key)

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)
