Class SizeConstraint

    • Method Detail

      • fieldToMatch

        public final FieldToMatch fieldToMatch()

        Specifies where in a web request to look for the size constraint.

        Returns:
        Specifies where in a web request to look for the size constraint.
      • textTransformation

        public final TextTransformation textTransformation()

        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 FieldToMatch before inspecting it for a match.

        You can only specify a single type of TextTransformation.

        Note that if you choose BODY for the value of Type, you must choose NONE for TextTransformation because CloudFront forwards only the first 8192 bytes for inspection.

        NONE

        Specify NONE if you don't want to perform any text transformations.

        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 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).

        URL_DECODE

        Use this option to decode a URL-encoded value.

        If the service returns an enum value that is not available in the current SDK version, textTransformation will return TextTransformation.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from textTransformationAsString().

        Returns:
        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 FieldToMatch before inspecting it for a match.

      • comparisonOperator

        public final ComparisonOperator comparisonOperator()

        The type of comparison you want AWS WAF to perform. AWS WAF uses this in combination with the provided Size and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

        EQ: Used to test if the Size is equal to the size of the FieldToMatch

        NE: Used to test if the Size is not equal to the size of the FieldToMatch

        LE: Used to test if the Size is less than or equal to the size of the FieldToMatch

      • size

        public final Long size()

        The size in bytes that you want AWS WAF to compare against the size of the specified FieldToMatch. AWS WAF uses this in combination with ComparisonOperator and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

        Valid values for size are 0 - 21474836480 bytes (0 - 20 GB).

        If you specify URI for the value of Type, the / in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.
