Functions
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.
requests you want to allow or block based on the country that the requests
originate from. For example, if you're receiving a lot of requests from one
or more countries and you want to block the requests, you can create an
GeoMatchSet
that contains those countries and then configure AWS WAF to
block the requests.
that 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.
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

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.
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.
- `INSYNC`: Propagation is complete.

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.

Tagging is only available through the API, SDKs, and CLI. You can't manage or view tags through the AWS WAF Classic console. You can tag the AWS resources that you manage through AWS WAF Classic: web ACLs, rule groups, and rules.
You can access information about all traffic that AWS WAF inspects using the following steps:
- Create an Amazon Kinesis Data Firehose.
Create the data firehose with a PUT source and in the region that you are
operating. However, if you are capturing logs for Amazon CloudFront, always
create the firehose in US East (N. Virginia).
Do not create the data firehose using a `Kinesis stream` as your source. - Associate that firehose to your web ACL using a `PutLoggingConfiguration` request.
supported use for this action is to share a RuleGroup across accounts.
The PutPermissionPolicy
is subject to the following restrictions:
- You can attach only one policy with each `PutPermissionPolicy` request.
- The policy must include an `Effect`, `Action` and `Principal`.
- `Effect` must specify `Allow`.
- The `Action` in the policy must be `waf:UpdateWebACL`, `waf-regional:UpdateWebACL`, `waf:GetRuleGroup` and `waf-regional:GetRuleGroup` . Any extra or wildcard actions in the policy will be rejected.
- The policy cannot include a `Resource` parameter.
- The ARN in the request must be a valid WAF RuleGroup ARN and the RuleGroup must exist in the same region.
- The user making the request must be the owner of the RuleGroup.
- Your policy must be composed using IAM Policy version 2012-10-17.

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.

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
- A `ByteMatchSet` with `FieldToMatch` of [`URI`](https://hexdocs.pm/elixir/URI.html)
- A `PositionalConstraint` of `STARTS_WITH`
- A `TargetString` of `login`
RegexMatchSet

object, you specify the
following values:
- Whether to insert or delete the object from the array. If you want to change a `RegexMatchSetUpdate` object, you delete the existing object and add a new one.
- The part of a web request that you want AWS WAF to inspectupdate, such as a query string or the value of the `User-Agent` header.
- The identifier of the pattern (a regular expression) that you want AWS WAF to look for. For more information, see `RegexPatternSet`.
- Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.
- Create a `RegexMatchSet.` For more information, see `CreateRegexMatchSet`.
- Use `GetChangeToken` to get the change token that you provide in the `ChangeToken` parameter of an `UpdateRegexMatchSet` request.
- Submit an `UpdateRegexMatchSet` request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the identifier of the `RegexPatternSet` that contain the regular expression patters you want AWS WAF to watch for.
RegexPatternSet
. For each RegexPatternString
object, you specify the

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 that 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`
- Create and update the predicates that you want to include in the `Rule`.
- Create the `Rule`. See `CreateRule`.
- Use `GetChangeToken` to get the change token that you provide in the `ChangeToken` parameter of an `UpdateRule` request.
- Submit an `UpdateRule` request to add predicates to the `Rule`.
- Create and update a `WebACL` that contains the `Rule`. See `CreateWebACL`.
You can only insert REGULAR
rules into a rule group.
You can have a maximum of ten rules per rule group.
To create and configure a RuleGroup
, perform the following steps:
- Create and update the `Rules` that you want to include in the `RuleGroup`. See `CreateRule`.
- Use `GetChangeToken` to get the change token that you provide in the `ChangeToken` parameter of an `UpdateRuleGroup` request.
- Submit an `UpdateRuleGroup` request to add `Rules` to the `RuleGroup`.
- Create and update a `WebACL` that contains the `RuleGroup`. See `CreateWebACL`.
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. You can only specify a single type of TextTransformation.
- 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.
- Create a `SizeConstraintSet.` For more information, see `CreateSizeConstraintSet`.
- Use `GetChangeToken` to get the change token that you provide in the `ChangeToken` parameter of an `UpdateSizeConstraintSet` request.
- 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.
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 or custom query parameter, the name of the header or parameter.
- `TextTransformation`: Which text transformation, if any, to perform on the web request before inspecting the request for snippets of malicious SQL code. You can only specify a single type of TextTransformation.
- Submit a `CreateSqlInjectionMatchSet` request.
- Use `GetChangeToken` to get the change token that you provide in the `ChangeToken` parameter of an `UpdateIPSet` request.
- Submit an `UpdateSqlInjectionMatchSet` request to specify the parts of web requests that you want AWS WAF to inspect for snippets of SQL code.
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 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 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.
- Create and update the predicates that you want to include in `Rules`. For more information, see `CreateByteMatchSet`, `UpdateByteMatchSet`, `CreateIPSet`, `UpdateIPSet`, `CreateSqlInjectionMatchSet`, and `UpdateSqlInjectionMatchSet`.
- Create and update the `Rules` that you want to include in the `WebACL`. For more information, see `CreateRule` and `UpdateRule`.
- Create a `WebACL`. See `CreateWebACL`.
- Use `GetChangeToken` to get the change token that you provide in the `ChangeToken` parameter of an `UpdateWebACL` request.
- 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. The `ActivatedRule` can be a rule group. If you specify a rule group as your `ActivatedRule` , you can exclude specific rules from that rule group. If you already have a rule group associated with a web ACL and want to submit an `UpdateWebACL` request to exclude certain rules from that rule group, you must first remove the rule group from the web ACL, the re-insert it again, specifying the excluded rules. For details, see `ActivatedRule$ExcludedRules` .
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 an `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 or custom query parameter, the name of the header or parameter.
- `TextTransformation`: Which text transformation, if any, to perform on the web request before inspecting the request for cross-site scripting attacks. You can only specify a single type of TextTransformation.
- Submit a `CreateXssMatchSet` request.
- Use `GetChangeToken` to get the change token that you provide in the `ChangeToken` parameter of an `UpdateIPSet` request.
