Description

Updates the specified WebACL. While updating a web ACL, WAF provides continous coverage to the resources that you have associated with the web ACL. When you make changes to web ACLs or web ACL components, like rules and rule groups, WAF propagates the changes everywhere that the web ACL and its components are stored and used. Your changes are applied within seconds, but there might be a brief period of inconsistency when the changes have arrived in some places and not in others. So, for example, if you change a rule action setting, the action might be the old action in one area and the new action in another area. Or if you add an IP address to an IP set used in a blocking rule, the new address might briefly be blocked in one area while still allowed in another. This temporary inconsistency can occur when you first associate a web ACL with an Amazon Web Services resource and when you change a web ACL that is already associated with a resource. Generally, any inconsistencies of this type last only a few seconds. This operation completely replaces the mutable specifications that you already have for the web ACL with the ones that you provide to this call. To modify the web ACL, retrieve it by calling GetWebACL, update the settings as needed, and then provide the complete web ACL specification to this call. A web ACL defines a collection of rules to use to inspect and control web requests. Each rule has an action defined (allow, block, or count) for requests that match the statement of the rule. In the web ACL, you assign a default action to take (allow, block) for any request that does not match any of the rules. The rules in a web ACL can be a combination of the types Rule, RuleGroup, and managed rule group. You can associate a web ACL with one or more Amazon Web Services resources to protect. The resources can be an Amazon CloudFront distribution, an Amazon API Gateway REST API, an Application Load Balancer, or an AppSync GraphQL API.

Parameters

-CustomResponseBody <Hashtable>
A map of custom response keys and content bodies. When you create a rule with a block action, you can send a custom response to the web request. You define these for the web ACL, and then use them in the rules and default actions that you define in the web ACL. For information about customizing web requests and responses, see Customizing web requests and responses in WAF in the WAF Developer Guide. For information about the limits on count and size for custom request and response settings, see WAF quotas in the WAF Developer Guide.

This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Id <String>
The unique identifier for the web ACL. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

AliasesCaptchaConfig_ImmunityTimeProperty_ImmunityTime
-LockToken <String>
A token used for optimistic locking. WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException. If this happens, perform another get, and use the new token returned by that operation.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Name <String>
The name of the web ACL. You cannot change the name of a web ACL after you create it.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the Id parameter. The -PassThru parameter is deprecated, use -Select '^Id' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Rule <Rule[]>
The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that WAF uses to identify matching web requests, and parameters that govern how WAF handles them.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRules
-Scope <Scope>
Specifies whether this is for an Amazon CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, or an AppSync GraphQL API. To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:
  • CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1.
  • API and SDKs - For all calls, use the Region endpoint us-east-1.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'NextLockToken'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.WAFV2.Model.UpdateWebACLResponse). Specifying the name of a property of type Amazon.WAFV2.Model.UpdateWebACLResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.

Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage.

Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
