Classes

NameDescription
Class ActivatedRule

The ActivatedRule object in an UpdateWebACL request specifies a Rule that you want to insert or delete, the priority of the Rule in the WebACL, and the action that you want AWS WAF to take when a web request matches the Rule (ALLOW, BLOCK, or COUNT).

To specify whether to insert or delete a Rule, use the Action parameter in the WebACLUpdate data type.

Class AssociateWebACLRequest

Container for the parameters to the AssociateWebACL operation. Associates a web ACL with a resource.

Class AssociateWebACLResponse

This is the response object from the AssociateWebACL operation.

Class ByteMatchSet

In a GetByteMatchSet request, ByteMatchSet is a complex type that contains the ByteMatchSetId and Name of a ByteMatchSet, and the values that you specified when you updated the ByteMatchSet.

A complex type that contains ByteMatchTuple objects, which specify the parts of web requests that you want AWS WAF to inspect and the values that you want AWS WAF to search for. If a ByteMatchSet contains more than one ByteMatchTuple object, a request needs to match the settings in only one ByteMatchTuple to be considered a match.

Class ByteMatchSetSummary

Returned by ListByteMatchSets. Each ByteMatchSetSummary object includes the Name and ByteMatchSetId for one ByteMatchSet.

Class ByteMatchSetUpdate

In an UpdateByteMatchSet request, ByteMatchSetUpdate specifies whether to insert or delete a ByteMatchTuple and includes the settings for the ByteMatchTuple.

Class ByteMatchTuple

The bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to search for in web requests, the location in requests that you want AWS WAF to search, and other settings.

Class CreateByteMatchSetRequest

Container for the parameters to the CreateByteMatchSet operation. Creates a ByteMatchSet. You then use UpdateByteMatchSet to identify the part of a web request that you want AWS WAF to inspect, such as the values of the User-Agent header or the query string. For example, you can create a ByteMatchSet that matches any requests with User-Agent headers that contain the string BadBot. You can then configure AWS WAF to reject those requests.

To create and configure a ByteMatchSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateByteMatchSet request.

  2. Submit a CreateByteMatchSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateByteMatchSet request.

  4. Submit an UpdateByteMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Class CreateByteMatchSetResponse

This is the response object from the CreateByteMatchSet operation.

Class CreateIPSetRequest

Container for the parameters to the CreateIPSet operation. Creates an IPSet, which you use to specify which web requests you want to allow or block based on the IP addresses that the requests originate from. For example, if you're receiving a lot of requests from one or more individual IP addresses or one or more ranges of IP addresses and you want to block the requests, you can create an IPSet that contains those IP addresses and then configure AWS WAF to block the requests.

To create and configure an IPSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateIPSet request.

  2. Submit a CreateIPSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  4. Submit an UpdateIPSet request to specify the IP addresses that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Class CreateIPSetResponse

This is the response object from the CreateIPSet operation.

Class CreateRateBasedRuleRequest

Container for the parameters to the CreateRateBasedRule operation. Creates a RateBasedRule. The RateBasedRule contains a RateLimit, which specifies the maximum number of requests that AWS WAF allows from a specified IP address in a five-minute period. The RateBasedRule also contains the IPSet objects, ByteMatchSet objects, and other predicates that identify the requests that you want to count or block if these requests exceed the RateLimit.

If you add more than one predicate to a RateBasedRule, a request not only must exceed the RateLimit, but it also must match all the specifications to be counted or blocked. For example, suppose you add the following to a RateBasedRule:

  • An IPSet that matches the IP address 192.0.2.44/32

  • A ByteMatchSet that matches BadBot in the User-Agent header

Further, you specify a RateLimit of 15,000.

You then add the RateBasedRule to a WebACL and specify that you want to block requests that meet the conditions in the rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot. Further, requests that match these two conditions must be received at a rate of more than 15,000 requests every five minutes. If both conditions are met and the rate is exceeded, AWS WAF blocks the requests. If the rate drops below 15,000 for a five-minute period, AWS WAF no longer blocks the requests.

As a second example, suppose you want to limit requests to a particular page on your site. To do this, you could add the following to a RateBasedRule:

  • A ByteMatchSet with FieldToMatch of URI

  • A PositionalConstraint of STARTS_WITH

  • A TargetString of login

Further, you specify a RateLimit of 15,000.

By adding this RateBasedRule to a WebACL, you could limit requests to your login page without affecting the rest of your site.

To create and configure a RateBasedRule, perform the following steps:

  1. Create and update the predicates that you want to include in the rule. For more information, see CreateByteMatchSet, CreateIPSet, and CreateSqlInjectionMatchSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateRule request.

  3. Submit a CreateRateBasedRule request.

  4. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.

  5. Submit an UpdateRateBasedRule request to specify the predicates that you want to include in the rule.

  6. Create and update a WebACL that contains the RateBasedRule. For more information, see CreateWebACL.

  • An IPSet that matches the IP address 192.0.2.44/32

  • A ByteMatchSet that matches BadBot in the User-Agent header

You then add the Rule to a WebACL and specify that you want to blocks requests that satisfy the Rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot.

To create and configure a Rule, perform the following steps:

  1. Create and update the predicates that you want to include in the Rule. For more information, see CreateByteMatchSet, CreateIPSet, and CreateSqlInjectionMatchSet.

The response to a CreateSqlInjectionMatchSet request.

Class CreateWebACLRequest

Container for the parameters to the CreateWebACL operation. Creates a WebACL, which contains the Rules that identify the CloudFront web requests that you want to allow, block, or count. AWS WAF evaluates Rules in order based on the value of Priority for each Rule.

You also specify a default action, either ALLOW or BLOCK. If a web request doesn't match any of the Rules in a WebACL, AWS WAF responds to the request with the default action.

To create and configure a WebACL, perform the following steps:

  1. Create and update the ByteMatchSet objects and other predicates that you want to include in Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.

Class Predicate

Specifies the ByteMatchSet, IPSet, SqlInjectionMatchSet, XssMatchSet, and SizeConstraintSet objects that you want to add to a Rule and, for each object, indicates whether you want to negate the settings, for example, requests that do NOT originate from the IP address 192.0.2.44.

Class RateBasedRule

A RateBasedRule is identical to a regular Rule, with one addition: a RateBasedRule counts the number of requests that arrive from a specified IP address every five minutes. For example, based on recent requests that you've seen from an attacker, you might create a RateBasedRule that includes the following conditions:

  • The requests come from 192.0.2.44.

  • They contain the value BadBot in the User-Agent header.

In the rule, you also define the rate limit as 15,000.

Requests that meet both of these conditions and exceed 15,000 requests every five minutes trigger the rule's action (block or count), which is defined in the web ACL.

Class Rule

A combination of ByteMatchSet, IPSet, and/or SqlInjectionMatchSet objects that identify the web requests that you want to allow, block, or count. For example, you might create a Rule that includes the following predicates:

  • An IPSet that causes AWS WAF to search for web requests that originate from the IP address 192.0.2.44

  • A ByteMatchSet that causes AWS WAF to search for web requests for which the value of the User-Agent header is BadBot.

To match the settings in this Rule, a request must originate from 192.0.2.44 AND include a User-Agent header for which the value is BadBot.

Class RuleSummary

Contains the identifier and the friendly name or description of the Rule.

Class RuleUpdate

Specifies a Predicate (such as an IPSet) and indicates whether you want to add it to a Rule or delete it from a Rule.

Class SampledHTTPRequest

The response from a GetSampledRequests request includes a SampledHTTPRequests complex type that appears as SampledRequests in the response syntax. SampledHTTPRequests contains one SampledHTTPRequest object for each web request that is returned by GetSampledRequests.

Class SizeConstraint

Specifies a constraint on the size of a part of the web request. AWS WAF uses the Size, ComparisonOperator, and FieldToMatch to build an expression in the form of "SizeComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

Class SizeConstraintSet

A complex type that contains SizeConstraint objects, which specify the parts of web requests that you want AWS WAF to inspect the size of. If a SizeConstraintSet contains more than one SizeConstraint object, a request only needs to match one constraint to be considered a match.

Class SizeConstraintSetSummary

The Id and Name of a SizeConstraintSet.

Class SizeConstraintSetUpdate

Specifies the part of a web request that you want to inspect the size of and indicates whether you want to add the specification to a SizeConstraintSet or delete it from a SizeConstraintSet.

Class SqlInjectionMatchSet

A complex type that contains SqlInjectionMatchTuple objects, which specify the parts of web requests that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header. If a SqlInjectionMatchSet contains more than one SqlInjectionMatchTuple object, a request needs to include snippets of SQL code in only one of the specified parts of the request to be considered a match.

Class SqlInjectionMatchSetSummary

The Id and Name of a SqlInjectionMatchSet.

Class SqlInjectionMatchSetUpdate

Specifies the part of a web request that you want to inspect for snippets of malicious SQL code and indicates whether you want to add the specification to a SqlInjectionMatchSet or delete it from a SqlInjectionMatchSet.

Class SqlInjectionMatchTuple

Specifies the part of a web request that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header.

Class TimeWindow

In a GetSampledRequests request, the StartTime and EndTime objects specify the time range for which you want AWS WAF to return a sample of web requests.

In a GetSampledRequests response, the StartTime and EndTime objects specify the time range for which AWS WAF actually returned a sample of web requests. AWS WAF gets the specified number of requests from among the first 5,000 requests that your AWS resource receives during the specified time period. If your resource receives more than 5,000 requests during that period, AWS WAF stops sampling after the 5,000th request. In that case, EndTime is the time that AWS WAF received the 5,000th request.

Class UpdateByteMatchSetRequest

Container for the parameters to the UpdateByteMatchSet operation. Inserts or deletes ByteMatchTuple objects (filters) in a ByteMatchSet. For each ByteMatchTuple object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change a ByteMatchSetUpdate object, you delete the existing object and add a new one.

  • The part of a web request that you want AWS WAF to inspect, such as a query string or the value of the User-Agent header.

  • The bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to look for. For more information, including how you specify the values for the AWS WAF API and the AWS CLI or SDKs, see TargetString in the ByteMatchTuple data type.

  • Where to look, such as at the beginning or the end of a query string.

  • Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.

For example, you can add a ByteMatchSetUpdate object that matches web requests in which User-Agent headers contain the string BadBot. You can then configure AWS WAF to block those requests.

To create and configure a ByteMatchSet, perform the following steps:

  1. Create a ByteMatchSet. For more information, see CreateByteMatchSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateByteMatchSet request.

  3. Submit an UpdateByteMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Class UpdateByteMatchSetResponse

This is the response object from the UpdateByteMatchSet operation.

Class UpdateIPSetRequest

Container for the parameters to the UpdateIPSet operation. Inserts or deletes IPSetDescriptor objects in an IPSet. For each IPSetDescriptor object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change an IPSetDescriptor object, you delete the existing object and add a new one.

  • The IP address version, IPv4 or IPv6.

  • The IP address in CIDR notation, for example, 192.0.2.0/24 (for the range of IP addresses from 192.0.2.0 to 192.0.2.255) or 192.0.2.44/32 (for the individual IP address 192.0.2.44).

AWS WAF supports /8, /16, /24, and /32 IP address ranges for IPv4, and /24, /32, /48, /56, /64 and /128 for IPv6. For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing.

IPv6 addresses can be represented using any of the following formats:

  • 1111:0000:0000:0000:0000:0000:0000:0111/128

  • 1111:0:0:0:0:0:0:0111/128

  • 1111::0111/128

  • 1111::111/128

You use an IPSet to specify which web requests you want to allow or block based on the IP addresses that the requests originated from. For example, if you're receiving a lot of requests from one or a small number of IP addresses and you want to block the requests, you can create an IPSet that specifies those IP addresses, and then configure AWS WAF to block the requests.

To create and configure an IPSet, perform the following steps:

  1. Submit a CreateIPSet request.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  3. Submit an UpdateIPSet request to specify the IP addresses that you want AWS WAF to watch for.

When you update an IPSet, you specify the IP addresses that you want to add and/or the IP addresses that you want to delete. If you want to change an IP address, you delete the existing IP address and add the new one.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Class UpdateIPSetResponse

This is the response object from the UpdateIPSet operation.

Class UpdateRateBasedRuleRequest

Container for the parameters to the UpdateRateBasedRule operation. Inserts or deletes Predicate objects in a rule and updates the RateLimit in the rule.

Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet, that specifies the web requests that you want to block or count. The RateLimit specifies the number of requests every five minutes that triggers the rule.

If you add more than one predicate to a RateBasedRule, a request must match all the predicates and exceed the RateLimit to be counted or blocked. For example, suppose you add the following to a RateBasedRule:

  • An IPSet that matches the IP address 192.0.2.44/32

  • A ByteMatchSet that matches BadBot in the User-Agent header

Further, you specify a RateLimit of 15,000.

You then add the RateBasedRule to a WebACL and specify that you want to block requests that satisfy the rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot. Further, requests that match these two conditions much be received at a rate of more than 15,000 every five minutes. If the rate drops below this limit, AWS WAF no longer blocks the requests.

As a second example, suppose you want to limit requests to a particular page on your site. To do this, you could add the following to a RateBasedRule:

  • A ByteMatchSet with FieldToMatch of URI

  • A PositionalConstraint of STARTS_WITH

  • A TargetString of login

Further, you specify a RateLimit of 15,000.

By adding this RateBasedRule to a WebACL, you could limit requests to your login page without affecting the rest of your site.

Class UpdateRateBasedRuleResponse

This is the response object from the UpdateRateBasedRule operation.

Class UpdateRuleRequest

Container for the parameters to the UpdateRule operation. Inserts or deletes Predicate objects in a Rule. Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet, that specifies the web requests that you want to allow, block, or count. If you add more than one predicate to a Rule, a request must match all of the specifications to be allowed, blocked, or counted. For example, suppose you add the following to a Rule:

  • A ByteMatchSet that matches the value BadBot in the User-Agent header

  • An IPSet that matches the IP address 192.0.2.44

You then add the Rule to a WebACL and specify that you want to block requests that satisfy the Rule. For a request to be blocked, the User-Agent header in the request must contain the value BadBotand the request must originate from the IP address 192.0.2.44.

To create and configure a Rule, perform the following steps:

  1. Create and update the predicates that you want to include in the Rule.

  2. Create the Rule. See CreateRule.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.

  4. Submit an UpdateRule request to add predicates to the Rule.

  5. Create and update a WebACL that contains the Rule. See CreateWebACL.

If you want to replace one ByteMatchSet or IPSet with another, you delete the existing one and add the new one.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Class UpdateRuleResponse

This is the response object from the UpdateRule operation.

Class UpdateSizeConstraintSetRequest

Container for the parameters to the UpdateSizeConstraintSet operation. Inserts or deletes SizeConstraint objects (filters) in a SizeConstraintSet. For each SizeConstraint object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change a SizeConstraintSetUpdate object, you delete the existing object and add a new one.

  • The part of a web request that you want AWS WAF to evaluate, such as the length of a query string or the length of the User-Agent header.

  • Whether to perform any transformations on the request, such as converting it to lowercase, before checking its length. Note that transformations of the request body are not supported because the AWS resource forwards only the first 8192 bytes of your request to AWS WAF.

  • A ComparisonOperator used for evaluating the selected part of the request against the specified Size, such as equals, greater than, less than, and so on.

  • The length, in bytes, that you want AWS WAF to watch for in selected part of the request. The length is computed after applying the transformation.

For example, you can add a SizeConstraintSetUpdate object that matches web requests in which the length of the User-Agent header is greater than 100 bytes. You can then configure AWS WAF to block those requests.

To create and configure a SizeConstraintSet, perform the following steps:

  1. Create a SizeConstraintSet. For more information, see CreateSizeConstraintSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateSizeConstraintSet request.

  3. Submit an UpdateSizeConstraintSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Class UpdateSizeConstraintSetResponse

This is the response object from the UpdateSizeConstraintSet operation.

Class UpdateSqlInjectionMatchSetRequest

Container for the parameters to the UpdateSqlInjectionMatchSet operation. 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:

  1. Submit a CreateSqlInjectionMatchSet request.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  3. 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.

Class UpdateSqlInjectionMatchSetResponse

The response to an UpdateSqlInjectionMatchSets request.

Class UpdateWebACLRequest

Container for the parameters to the UpdateWebACL operation. Inserts or deletes ActivatedRule objects in a WebACL. Each Rule identifies web requests that you want to allow, block, or count. When you update a WebACL, you specify the following values:

  • A default action for the WebACL, either ALLOW or BLOCK. AWS WAF performs the default action if a request doesn't match the criteria in any of the Rules in a WebACL.

  • The Rules that you want to add and/or delete. If you want to replace one Rule with another, you delete the existing Rule and add the new one.

  • For each Rule, whether you want AWS WAF to allow requests, block requests, or count requests that match the conditions in the Rule.

  • The order in which you want AWS WAF to evaluate the Rules in a WebACL. If you add more than one Rule to a WebACL, AWS WAF evaluates each request against the Rules in order based on the value of Priority. (The Rule that has the lowest value for Priority is evaluated first.) When a web request matches all of the predicates (such as ByteMatchSets and IPSets) in a Rule, AWS WAF immediately takes the corresponding action, allow or block, and doesn't evaluate the request against the remaining Rules in the WebACL, if any.

To create and configure a WebACL, perform the following steps:

  1. Create and update the predicates that you want to include in Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.

  2. Create and update the Rules that you want to include in the WebACL. For more information, see CreateRule and UpdateRule.

  3. Create a WebACL. See CreateWebACL.

  4. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.

  5. Submit an UpdateWebACL request to specify the Rules that you want to include in the WebACL, to specify the default action, and to associate the WebACL with a CloudFront distribution.

Be aware that if you try to add a RATE_BASED rule to a web ACL without setting the rule type when first creating the rule, the UpdateWebACL request will fail because the request tries to add a REGULAR rule (the default rule type) with the specified ID, which does not exist.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Class UpdateWebACLResponse

This is the response object from the UpdateWebACL operation.

Class UpdateXssMatchSetRequest

Container for the parameters to the UpdateXssMatchSet operation. Inserts or deletes XssMatchTuple objects (filters) in an XssMatchSet. For each XssMatchTuple object, you specify the following values:

  • Action: Whether to insert the object into or delete the object from the array. To change a XssMatchTuple, 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 cross-site scripting attacks.

You use XssMatchSet objects to specify which CloudFront requests you want to allow, block, or count. For example, if you're receiving requests that contain cross-site scripting attacks in the request body and you want to block the requests, you can create an XssMatchSet with the applicable settings, and then configure AWS WAF to block the requests.

To create and configure an XssMatchSet, perform the following steps:

  1. Submit a CreateXssMatchSet request.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  3. Submit an UpdateXssMatchSet request to specify the parts of web requests that you want AWS WAF to inspect for cross-site scripting attacks.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Class UpdateXssMatchSetResponse

The response to an UpdateXssMatchSets request.

Class WafAction

For the action that is associated with a rule in a WebACL, specifies the action that you want AWS WAF to perform when a web request matches all of the conditions in a rule. For the default action in a WebACL, specifies the action that you want AWS WAF to take when a web request doesn't match all of the conditions in any of the rules in a WebACL.

Class WebACL

Contains the Rules that identify the requests that you want to allow, block, or count. In a WebACL, you also specify a default action (ALLOW or BLOCK), and the action for each Rule that you add to a WebACL, for example, block requests from specified IP addresses or block requests from specified referrers. You also associate the WebACL with a CloudFront distribution to identify the requests that you want AWS WAF to filter. If you add more than one Rule to a WebACL, a request needs to match only one of the specifications to be allowed, blocked, or counted. For more information, see UpdateWebACL.

Class WebACLSummary

Contains the identifier and the name or description of the WebACL.

Class WebACLUpdate

Specifies whether to insert a Rule into or delete a Rule from a WebACL.

Class XssMatchSet

A complex type that contains XssMatchTuple objects, which specify the parts of web requests that you want AWS WAF to inspect for cross-site scripting attacks and, if you want AWS WAF to inspect a header, the name of the header. If a XssMatchSet contains more than one XssMatchTuple object, a request needs to include cross-site scripting attacks in only one of the specified parts of the request to be considered a match.

Class XssMatchSetSummary

The Id and Name of an XssMatchSet.

Class XssMatchSetUpdate

Specifies the part of a web request that you want to inspect for cross-site scripting attacks and indicates whether you want to add the specification to an XssMatchSet or delete it from an XssMatchSet.

Class XssMatchTuple

Specifies the part of a web request that you want AWS WAF to inspect for cross-site scripting attacks and, if you want AWS WAF to inspect a header, the name of the header.
