Inserts or deletes
SqlInjectionMatchTuple objects (filters) in a
SqlInjectionMatchSet. For each
SqlInjectionMatchTuple
object, you specify the following values:
-
Action
: Whether to insert the object into or delete the object from the array. To change a SqlInjectionMatchTuple
, you delete the existing object and add a new one.
-
FieldToMatch
: The part of web requests that you want AWS WAF to inspect and, if you want AWS WAF to inspect a header, the name of the header.
-
TextTransformation
: Which text transformation, if any, to perform on the web request before inspecting the request for snippets of malicious SQL code.
You use SqlInjectionMatchSet
objects to specify which CloudFront requests you want to allow, block, or count. For example, if you're receiving requests that contain snippets of SQL code in the query string and you want to block the requests, you can create a SqlInjectionMatchSet
with the applicable settings, and then configure AWS WAF to block the requests.
To create and configure a SqlInjectionMatchSet
, perform the following steps:
-
Submit a CreateSqlInjectionMatchSet request.
-
Use GetChangeToken to get the change token that you provide in the ChangeToken
parameter of an UpdateIPSet request.
-
Submit an UpdateSqlInjectionMatchSet
request to specify the parts of web requests that you want AWS WAF to inspect for snippets of SQL code.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.
