Synopsis

Calls the AWS WAF UpdateRateBasedRule API operation.

Syntax

Update-WAFRateBasedRule
-RuleId <String>
-ChangeToken <String>
-RateLimit <Int64>
-Update <RuleUpdate[]>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use. Inserts or deletes Predicate objects in a rule and updates the RateLimit in the rule. Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet, that specifies the web requests that you want to block or count. The RateLimit specifies the number of requests every five minutes that triggers the rule. If you add more than one predicate to a RateBasedRule, a request must match all the predicates and exceed the RateLimit to be counted or blocked. For example, suppose you add the following to a RateBasedRule:
  • An IPSet that matches the IP address 192.0.2.44/32
  • A ByteMatchSet that matches BadBot in the User-Agent header
Further, you specify a RateLimit of 1,000. You then add the RateBasedRule to a WebACL and specify that you want to block requests that satisfy the rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot. Further, requests that match these two conditions much be received at a rate of more than 1,000 every five minutes. If the rate drops below this limit, AWS WAF no longer blocks the requests. As a second example, suppose you want to limit requests to a particular page on your site. To do this, you could add the following to a RateBasedRule:
  • A ByteMatchSet with FieldToMatch of URI
  • A PositionalConstraint of STARTS_WITH
  • A TargetString of login
Further, you specify a RateLimit of 1,000. By adding this RateBasedRule to a WebACL, you could limit requests to your login page without affecting the rest of your site.

Parameters

-ChangeToken <String>
The value returned by the most recent call to GetChangeToken.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
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)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the RuleId parameter. The -PassThru parameter is deprecated, use -Select '^RuleId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-RateLimit <Int64>
The maximum number of requests, which have an identical value in the field specified by the RateKey, allowed in a five-minute period. If the number of requests exceeds the RateLimit and the other predicates specified in the rule are also met, AWS WAF triggers the action that is specified for this rule.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-RuleId <String>
The RuleId of the RateBasedRule that you want to update. RuleId is returned by CreateRateBasedRule and by ListRateBasedRules.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'ChangeToken'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.WAF.Model.UpdateRateBasedRuleResponse). Specifying the name of a property of type Amazon.WAF.Model.UpdateRateBasedRuleResponse 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
Accept pipeline input?True (ByPropertyName)
-Update <RuleUpdate[]>
An array of RuleUpdate objects that you want to insert into or delete from a RateBasedRule.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesUpdates

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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
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. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). 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 with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesSK, SecretAccessKey
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Outputs

System.String or Amazon.WAF.Model.UpdateRateBasedRuleResponse
This cmdlet returns a System.String object. The service call response (type Amazon.WAF.Model.UpdateRateBasedRuleResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
