To get a high-level view of how Amazon WAF and other Amazon services work with most IAM features, see Amazon services that work with IAM in the IAM User Guide.

Identity-based policies for Amazon WAF

Supports identity-based policies: Yes

Identity-based policies are JSON permissions policy documents that you can attach to an identity, such as an IAM user, group of users, or role. These policies control what actions users and roles can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see Define custom IAM permissions with customer managed policies in the IAM User Guide.

With IAM identity-based policies, you can specify allowed or denied actions and resources as well as the conditions under which actions are allowed or denied. To learn about all of the elements that you can use in a JSON policy, see IAM JSON policy elements reference in the IAM User Guide.

To view examples of Amazon WAF identity-based policies, see Identity-based policy examples for Amazon WAF.

Resource-based policies within Amazon WAF

Supports resource-based policies: Yes

Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM role trust policies and Amazon S3 bucket policies. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must specify a principal in a resource-based policy. Principals can include accounts, users, roles, federated users, or Amazon Web Services services.

To enable cross-account access, you can specify an entire account or IAM entities in another account as the principal in a resource-based policy. For more information, see Cross account resource access in IAM in the IAM User Guide.

Amazon WAF uses resource based policies to support the sharing of rule groups across accounts. You share a rule group that you own with another Amazon account by providing the resource-based policy settings to the Amazon WAF API call PutPermissionPolicy or to an equivalent CLI or SDK call. For additional information, including examples and links to documentation for the other available languages, see PutPermissionPolicy in the Amazon WAF API Reference. This functionality isn't available through other means, such as the console or Amazon CloudFormation.

Policy actions for Amazon WAF

Supports policy actions: Yes

Administrators can use Amazon JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.

The Action element of a JSON policy describes the actions that you can use to allow or deny access in a policy. Include actions in a policy to grant permissions to perform the associated operation.

To see a list of Amazon WAF actions and permissions for each, see Actions defined by Amazon WAF V2 in the Service Authorization Reference.

Policy actions in Amazon WAF use the following prefix before the action:

wafv2

To specify multiple actions in a single statement, separate them with commas.

"Action": [
      "wafv2:action1",
      "wafv2:action2"
         ]

You can specify multiple actions using wildcards (*). For example, to specify all actions in Amazon WAF that begin with List, include the following action:

"Action": "wafv2:List*"

To view examples of Amazon WAF identity-based policies, see Identity-based policy examples for Amazon WAF.

Policy resources for Amazon WAF

Supports policy resources: Yes

Administrators can use Amazon JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.

The Resource JSON policy element specifies the object or objects to which the action applies. As a best practice, specify a resource using its Amazon Resource Name (ARN). For actions that don't support resource-level permissions, use a wildcard (*) to indicate that the statement applies to all resources.

"Resource": "*"

To see the list of Amazon WAF resource types and their ARNs, see Resources defined by Amazon WAF V2 in the Service Authorization Reference. To learn with which actions you can specify the ARN of each resource, see Actions defined by Amazon WAF V2. To allow or deny access to a subset of Amazon WAF resources, include the ARN of the resource in the resource element of your policy.

The ARNs of Amazon WAF wafv2 resources have the following format:

arn:partition:wafv2:region:account-id:scope/resource-type/resource-name/resource-id

For general information about ARN specifications, see Amazon Resource Names (ARNs) in the Amazon Web Services General Reference.

The following lists requirements that are specific to the ARNs of wafv2 resources:

  • region: For Amazon WAF resources that you use to protect Amazon CloudFront distributions, set this to us-east-1. Otherwise, set this to the Region you're using with your protected regional resources.

  • scope: Set the scope to global for use with an Amazon CloudFront distribution or regional for use with any of the regional resources that Amazon WAF supports. The regional resources are an Amazon API Gateway REST API, an Application Load Balancer, an Amazon AppSync GraphQL API, an Amazon Cognito user pool, an Amazon App Runner service, and an Amazon Verified Access instance.

  • resource-type: Specify one of the following values: webacl, rulegroup, ipset, regexpatternset, or managedruleset.

  • resource-name: Specify the name that you gave the Amazon WAF resource, or specify a wildcard (*) to indicate all resources that satisfy the other specifications in the ARN. You must either specify the resource name and resource ID or specify a wildcard for both.

  • resource-id: Specify the ID of the Amazon WAF resource, or specify a wildcard (*) to indicate all resources that satisfy the other specifications in the ARN. You must either specify the resource name and resource ID or specify a wildcard for both.

For example, the following ARN specifies all protection packs (web ACLs) with regional scope for the account 111122223333 in Region us-west-1:

arn:aws:wafv2:us-west-1:111122223333:regional/webacl/*/*

The following ARN specifies the rule group named MyIPManagementRuleGroup with global scope for the account 111122223333 in Region us-east-1:

arn:aws:wafv2:us-east-1:111122223333:global/rulegroup/MyIPManagementRuleGroup/1111aaaa-bbbb-cccc-dddd-example-id

To view examples of Amazon WAF identity-based policies, see Identity-based policy examples for Amazon WAF.

Policy condition keys for Amazon WAF

Supports service-specific policy condition keys: Yes

Administrators can use Amazon JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.

The Condition element specifies when statements execute based on defined criteria. You can create conditional expressions that use condition operators, such as equals or less than, to match the condition in the policy with values in the request. To see all Amazon global condition keys, see Amazon global condition context keys in the IAM User Guide.

In addition, Amazon WAF supports the following condition keys that you can use to provide fine-grained filtering for your IAM policies:

  • wafv2:LogDestinationResource

    This condition key takes an Amazon Resource Name (ARN) specification for the logging destination. This is the ARN that you provide for the logging destination when you use the REST API call PutLoggingConfiguration.

    You can explicitly specify an ARN and you can specify filtering for the ARN. The following example specifies filtering for Amazon S3 bucket ARNs that have a specific location and prefix. 

    "Condition": { "ArnLike": { "wafv2:LogDestinationResource": "arn:aws:s3:::aws-waf-logs-suffix/custom-prefix/*" } }

  • wafv2:LogScope

    This condition key defines the source of the logging configuration in a string. Currently, this is always set to the default of Customer, which indicates that the logging destination is owned and managed by you.

To see a list of Amazon WAF condition keys, see Condition keys for Amazon WAF V2 in the Service Authorization Reference. To learn with which actions and resources you can use a condition key, see Actions defined by Amazon WAF V2.

To view examples of Amazon WAF identity-based policies, see Identity-based policy examples for Amazon WAF.

ACLs in Amazon WAF

Supports ACLs: No

Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format.

ABAC with Amazon WAF

Supports ABAC (tags in policies): Partial

Attribute-based access control (ABAC) is an authorization strategy that defines permissions based on attributes called tags. You can attach tags to IAM entities and Amazon resources, then design ABAC policies to allow operations when the principal's tag matches the tag on the resource.

To control access based on tags, you provide tag information in the condition element of a policy using the aws:ResourceTag/key-name, aws:RequestTag/key-name, or aws:TagKeys condition keys.

If a service supports all three condition keys for every resource type, then the value is Yes for the service. If a service supports all three condition keys for only some resource types, then the value is Partial.

For more information about ABAC, see Define permissions with ABAC authorization in the IAM User Guide. To view a tutorial with steps for setting up ABAC, see Use attribute-based access control (ABAC) in the IAM User Guide.

Using temporary credentials with Amazon WAF

Supports temporary credentials: Yes

Temporary credentials provide short-term access to Amazon resources and are automatically created when you use federation or switch roles. Amazon recommends that you dynamically generate temporary credentials instead of using long-term access keys. For more information, see Temporary security credentials in IAM and Amazon Web Services services that work with IAM in the IAM User Guide.

Forward access sessions for service Amazon WAF

Supports forward access sessions (FAS): Yes

Forward access sessions (FAS) use the permissions of the principal calling an Amazon Web Services service, combined with the requesting Amazon Web Services service to make requests to downstream services. For policy details when making FAS requests, see Forward access sessions.

Service roles for Amazon WAF

Supports service roles: Yes

A service role is an IAM role that a service assumes to perform actions on your behalf. An IAM administrator can create, modify, and delete a service role from within IAM. For more information, see Create a role to delegate permissions to an Amazon Web Services service in the IAM User Guide.

Warning

Changing the permissions for a service role might break Amazon WAF functionality. Edit service roles only when Amazon WAF provides guidance to do so.

Service-linked roles for Amazon WAF

Supports service-linked roles: Yes

A service-linked role is a type of service role that is linked to an Amazon Web Services service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your Amazon Web Services account and are owned by the service. An IAM administrator can view, but not edit the permissions for service-linked roles.

For details about creating or managing Amazon WAF service-linked roles, see Using service-linked roles for Amazon WAF.
