Trait representing the capabilities of the WAF API. WAF clients implement this trait.

Required Methods

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.

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.

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.

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

Creates a Rule, which contains the IPSet objects, ByteMatchSet objects, and other predicates that identify the requests that you want to block. If you add more than one predicate to a Rule, a request must match all of the specifications to be allowed or blocked. For example, suppose you add the following to a Rule:

  • 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.

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

  3. Submit a CreateRule request.

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

  5. Submit an UpdateRule request to specify the predicates that you want to include in the Rule.

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

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

Creates a SizeConstraintSet. You then use UpdateSizeConstraintSet to identify the part of a web request that you want AWS WAF to check for length, such as the length of the User-Agent header or the length of the query string. For example, you can create a SizeConstraintSet that matches any requests that have a query string that is longer than 100 bytes. You can then configure AWS WAF to reject those requests.

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

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

  2. Submit a CreateSizeConstraintSet request.

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

  4. 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.

Creates a SqlInjectionMatchSet, which you use to allow, block, or count requests that contain snippets of SQL code in a specified part of web requests. AWS WAF searches for character sequences that are likely to be malicious strings.

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

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

  2. Submit a CreateSqlInjectionMatchSet request.

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

  4. Submit an UpdateSqlInjectionMatchSet request to specify the parts of web requests in which you want to allow, block, or count malicious 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.

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.

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

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

  4. Submit a CreateWebACL request.

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

  6. 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.

For more information about how to use the AWS WAF API, see the AWS WAF Developer Guide.

Creates an XssMatchSet, which you use to allow, block, or count requests that contain cross-site scripting attacks in the specified part of web requests. AWS WAF searches for character sequences that are likely to be malicious strings.

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

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

  2. Submit a CreateXssMatchSet request.

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

  4. Submit an UpdateXssMatchSet request to specify the parts of web requests in which you want to allow, block, or count 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.

Returns the ByteMatchSet specified by ByteMatchSetId.

When you want to create, update, or delete AWS WAF objects, get a change token and include the change token in the create, update, or delete request. Change tokens ensure that your application doesn't submit conflicting requests to AWS WAF.

Each create, update, or delete request must use a unique change token. If your application submits a GetChangeToken request and then submits a second GetChangeToken request before submitting a create, update, or delete request, the second GetChangeToken request returns the same value as the first GetChangeToken request.

When you use a change token in a create, update, or delete request, the status of the change token changes to PENDING, which indicates that AWS WAF is propagating the change to all AWS WAF servers. Use GetChangeTokenStatus to determine the status of your change token.

Returns the status of a ChangeToken that you got by calling GetChangeToken. ChangeTokenStatus is one of the following values:

  • PROVISIONED: You requested the change token by calling GetChangeToken, but you haven't used it yet in a call to create, update, or delete an AWS WAF object.

  • PENDING: AWS WAF is propagating the create, update, or delete request to all AWS WAF servers.

  • IN_SYNC: Propagation is complete.

Returns the IPSet that is specified by IPSetId.

Returns the RateBasedRule that is specified by the RuleId that you included in the GetRateBasedRule request.

Returns an array of IP addresses currently being blocked by the RateBasedRule that is specified by the RuleId. The maximum number of managed keys that will be blocked is 10,000. If more than 10,000 addresses exceed the rate limit, the 10,000 addresses with the highest rates will be blocked.

Returns the Rule that is specified by the RuleId that you included in the GetRule request.

Gets detailed information about a specified number of requests--a sample--that AWS WAF randomly selects from among the first 5,000 requests that your AWS resource received during a time range that you choose. You can specify a sample size of up to 500 requests, and you can specify any time range in the previous three hours.

GetSampledRequests returns a time range, which is usually the time range that you specified. However, if your resource (such as a CloudFront distribution) received 5,000 requests before the specified time range elapsed, GetSampledRequests returns an updated time range. This new time range indicates the actual period during which AWS WAF selected the requests in the sample.

Returns the SizeConstraintSet specified by SizeConstraintSetId.

Returns the SqlInjectionMatchSet that is specified by SqlInjectionMatchSetId.

Returns the WebACL that is specified by WebACLId.

Returns the XssMatchSet that is specified by XssMatchSetId.

Returns an array of ByteMatchSetSummary objects.

Returns an array of IPSetSummary objects in the response.

Returns an array of RuleSummary objects.

Returns an array of RuleSummary objects.

Returns an array of SizeConstraintSetSummary objects.

Returns an array of SqlInjectionMatchSet objects.

Returns an array of WebACLSummary objects in the response.

Returns an array of XssMatchSet objects.

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.

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.

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.

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 BadBot and 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.

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.

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.

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.

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.
