Remarks

For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

If you configure AWS WAF to inspect the request body, AWS WAF inspects only the number of bytes in the body up to the limit for the web ACL and protected resource type. If you know that the request body for your web requests should never exceed the inspection limit, you can use a size constraint statement to block requests that have a larger request body size. For more information about the inspection limits, see Body and JsonBody settings for the FieldToMatch data type.

If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

Properties

ComparisonOperator

The operator to use to compare the request part to the size setting.

public string? ComparisonOperator { get; set; }

Property Value

string

Remarks

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-wafv2-rulegroup-sizeconstraintstatement.html#cfn-wafv2-rulegroup-sizeconstraintstatement-comparisonoperator

FieldToMatch

The part of the web request that you want AWS WAF to inspect.

public object? FieldToMatch { get; set; }

Property Value

object

Remarks

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-wafv2-rulegroup-sizeconstraintstatement.html#cfn-wafv2-rulegroup-sizeconstraintstatement-fieldtomatch

Type union: either IResolvable or CfnRuleGroupPropsMixin.IFieldToMatchProperty

Size

The size, in byte, to compare to the request part, after any transformations.

public double? Size { get; set; }

Property Value

double?

Remarks

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-wafv2-rulegroup-sizeconstraintstatement.html#cfn-wafv2-rulegroup-sizeconstraintstatement-size

TextTransformations

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

public object? TextTransformations { get; set; }

Property Value

object

Remarks

If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
