NAME
Paws::WAFv2::TextTransformation
USAGE
This class represents one of two things:
Arguments in a call to a service
Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.
As an example, if Att1 is expected to be a Paws::WAFv2::TextTransformation object:
$service_obj->Method(Att1 => { Priority => $value, ..., Type => $value });
Results returned from an API call
Use accessors for each attribute. If Att1 is expected to be an Paws::WAFv2::TextTransformation object:
$result = $service_obj->Method(...);
$result->Att1->Priority
DESCRIPTION
This is the latest version of AWS WAF, named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html).
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
ATTRIBUTES
REQUIRED Priority => Int
Sets the relative processing order for multiple transformations that
are defined for a rule statement. AWS WAF processes all
transformations, from lowest priority to highest, before inspecting the
transformed content. The priorities don't need to be consecutive, but
they must all be different.
REQUIRED Type => Str
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: \ " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
\f, formfeed, decimal 12
\t, tab, decimal 9
\n, newline, decimal 10
\r, carriage return, decimal 13
\v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE
also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE
performs the following operations:
Replaces
(ampersand)quot;
with"
Replaces
(ampersand)nbsp;
with a non-breaking space, decimal 160Replaces
(ampersand)lt;
with a "less than" symbolReplaces
(ampersand)gt;
with>
Replaces characters that are represented in hexadecimal format,
(ampersand)(hash)xhhhh;
, with the corresponding charactersReplaces characters that are represented in decimal format,
(ampersand)(hash)nnnn;
, with the corresponding characters
LOWERCASE

Use this option to decode a URL-encoded value.
