(ByteMatchTuple).TextTransformation

Defined in github.com/aws/aws-sdk-go/service/waf/api.go

Description

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on TargetString before inspecting a request for a match.

CMD_LINE

When you're concerned that attackers are injecting an operating system commandline 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 160 Replaces (ampersand)lt; with a "less than" symbol Replaces (ampersand)gt; with > Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters LOWERCASE

Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
