Synopsis

Calls the AWS WAF Regional UpdateRegexMatchSet API operation.

Syntax

Update-WAFRRegexMatchSet
-RegexMatchSetId <String>
-ChangeToken <String>
-Update <RegexMatchSetUpdate[]>
-Force <SwitchParameter>

Description

Inserts or deletes RegexMatchTuple objects (filters) in a RegexMatchSet. For each RegexMatchSetUpdate object, you specify the following values:
  • Whether to insert or delete the object from the array. If you want to change a RegexMatchSetUpdate object, you delete the existing object and add a new one.
  • The part of a web request that you want AWS WAF to inspectupdate, such as a query string or the value of the User-Agent header.
  • The identifier of the pattern (a regular expression) that you want AWS WAF to look for. For more information, see RegexPatternSet.
  • Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.
For example, you can create a RegexPatternSet that matches any requests with User-Agent headers that contain the string B[a@]dB[o0]t. You can then configure AWS WAF to reject those requests. To create and configure a RegexMatchSet, perform the following steps:
  1. Create a RegexMatchSet. For more information, see CreateRegexMatchSet.
  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRegexMatchSet request.
  3. Submit an UpdateRegexMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the identifier of the RegexPatternSet that contain the regular expression patters you want AWS WAF to watch for.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

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? False
-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? False
-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. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

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? False
-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? False
-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? False
-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? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named

Only specify this parameter if you must direct the call to a specific custom endpoint.
