Returns:
Dict[str, Any]
A web ACL defines a collection of rules to use to inspect and control web requests. Each rule has an action defined
(allow, block, or count) for requests that match the statement of the rule. In the web ACL, you assign a default
action to take (allow, block) for any request that does not match any of the rules. The rules in a web ACL can be
a combination of the types Rule , RuleGroup , and managed rule group. You can associate a web ACL with one or more
Amazon Web Services resources to protect. The resources can be an Amazon CloudFront distribution, an Amazon API
Gateway REST API, an Application Load Balancer, or an AppSync GraphQL API.
Args:
name(text): The name of the web ACL. You cannot change the name of a web ACL after you create it.
scope(text): Specifies whether this is for an Amazon CloudFront distribution or for a regional application.
A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API,
or an AppSync GraphQL API.
To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:
* CLI -- Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
* API and SDKs -- For all calls, use the Region endpoint us-east-1.
default_action(Dict[str, Any]): The action to perform if none of the Rules contained in the WebACL match.
* Block (Dict[str, Any], optional): Specifies that WAF should block requests by default.
* CustomResponse (Dict[str, Any], optional): Defines a custom response for the web request. For information about customizing web requests
and responses, see Customizing web requests and responses in WAF in the WAF Developer Guide.
* ResponseCode (int): The HTTP status code to return to the client. For a list of status codes that you can use in
your custom reqponses, see Supported status codes for custom response in the WAF Developer
Guide.
* CustomResponseBodyKey (str, optional): References the response body that you want WAF to return to the web request client. You can
define a custom response for a rule action or a default web ACL action that is set to block. To
do this, you first define the response body key and value in the CustomResponseBodies setting
for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL
default action BlockAction setting, you reference the response body using this key.
* ResponseHeaders (List[Dict[str, Any]], optional): The HTTP headers to use in the response. Duplicate header names are not allowed. For
information about the limits on count and size for custom request and response settings, see WAF
quotas in the WAF Developer Guide.
* Name (str): The name of the custom header. For custom request header insertion, when WAF inserts the header
into the request, it prefixes this name x-amzn-waf-, to avoid confusion with the headers that
are already in the request. For example, for the header name sample, WAF inserts the header
x-amzn-waf-sample.
* Value (str): The value of the custom header.
* Allow (Dict[str, Any], optional): Specifies that WAF should allow requests by default.
* CustomRequestHandling (Dict[str, Any], optional): Defines custom handling for the web request. For information about customizing web requests and
responses, see Customizing web requests and responses in WAF in the WAF Developer Guide.
* InsertHeaders (List['CustomHTTPHeader']): The HTTP headers to insert into the request. Duplicate header names are not allowed. For
information about the limits on count and size for custom request and response settings, see WAF
quotas in the WAF Developer Guide.
visibility_config(Dict[str, Any]): Defines and enables Amazon CloudWatch metrics and web request sample collection.
* SampledRequestsEnabled (bool): A boolean indicating whether WAF should store a sampling of the web requests that match the
rules. You can view the sampled requests through the WAF console.
* CloudWatchMetricsEnabled (bool): A boolean indicating whether the associated resource sends metrics to Amazon CloudWatch. For the
list of available metrics, see WAF Metrics.
* MetricName (str): A name of the Amazon CloudWatch metric. The name can contain only the characters: A-Z, a-z, 0-9,
- (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can't
contain whitespace or metric names reserved for WAF, for example "All" and "Default_Action."
resource_id(text, optional): AWS WAF ID.
description(text, optional): A description of the web ACL that helps with identification.
rules(List[Dict[str, Any]], optional): The Rule statements used to identify the web requests that you want to allow, block, or count.
Each rule includes one top-level statement that WAF uses to identify matching web requests, and
parameters that govern how WAF handles them. Defaults to None.
* Name (str): The name of the rule. You can't change the name of a Rule after you create it.
* Priority (int): If you define more than one Rule in a WebACL, WAF evaluates each request against the Rules in
order based on the value of Priority. WAF processes rules with lower priority first. The
priorities don't need to be consecutive, but they must all be different.
* Statement (Dict[str, Any]): The WAF processing statement for the rule, for example ByteMatchStatement or
SizeConstraintStatement.
* ByteMatchStatement (Dict[str, Any], optional): A rule statement that defines a string match search for WAF to apply to web requests. The byte
match statement provides the bytes to search for, the location in requests that you want WAF to
search, and other settings. The bytes to search for are typically a string that corresponds with
ASCII characters. In the WAF console and the developer guide, this is refered to as a string
match statement.
* SearchString (ByteString): A string value that you want WAF to search for.
* FieldToMatch (Dict[str, Any]): The part of the web request that you want WAF to inspect. For more information, see
FieldToMatch.
* SingleHeader (Dict[str, Any], optional): Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or
Referer. This setting isn't case sensitive. Example JSON: "SingleHeader": { "Name": "haystack" }
Alternately, you can filter and inspect all headers with the Headers FieldToMatch setting.
* Name (str): The name of the query header to inspect.
* SingleQueryArgument (Dict[str, Any], optional): Inspect a single query argument. Provide the name of the query argument to inspect, such as
UserName or SalesRegion. The name can be up to 30 characters long and isn't case sensitive.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
* Name (str): The name of the query argument to inspect.
* AllQueryArguments (Dict, optional): Inspect all query arguments.
* UriPath (Dict, optional): Inspect the request URI path. This is the part of the web request that identifies a resource,
for example, /images/daily-ad.jpg.
* QueryString (Dict, optional): Inspect the query string. This is the part of a URL that appears after a ? character, if any.
* Body (Dict[str, Any], optional): Inspect the request body as plain text. The request body immediately follows the request
headers. This is the part of a request that contains any additional data that you want to send
to your web server as the HTTP request body, such as data from a form. Only the first 8 KB
(8192 bytes) of the request body are forwarded to WAF for inspection by the underlying host
service. For information about how to handle oversized request bodies, see the Body object
configuration.
* OversizeHandling (str, optional): What WAF should do if the body is larger than WAF can inspect.
* Method (Dict, optional): Inspect the HTTP method. The method indicates the type of operation that the request is asking
the origin to perform.
* JsonBody (Dict[str, Any], optional): Inspect the request body as JSON. The request body immediately follows the request headers. This
is the part of a request that contains any additional data that you want to send to your web
server as the HTTP request body, such as data from a form. Only the first 8 KB (8192 bytes) of
the request body are forwarded to WAF for inspection by the underlying host service. For
information about how to handle oversized request bodies, see the JsonBody object configuration.
* MatchPattern (Dict[str, Any]): The patterns to look for in the JSON body. WAF inspects the results of these pattern matches
against the rule inspection criteria.
* All (Dict, optional): Match all of the elements. See also MatchScope in JsonBody. You must specify either this
setting or the IncludedPaths setting, but not both.
* IncludedPaths (List[str], optional): Match only the specified include paths. See also MatchScope in JsonBody. Provide the include
paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"].
For information about this syntax, see the Internet Engineering Task Force (IETF) documentation
JavaScript Object Notation (JSON) Pointer. You must specify either this setting or the All
setting, but not both. Don't use this option to include all paths. Instead, use the All
setting.
* MatchScope (str): The parts of the JSON to match against using the MatchPattern. If you specify All, WAF matches
against keys and values.
* InvalidFallbackBehavior (str, optional): What WAF should do if it fails to completely parse the JSON body.
The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and
inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
* OversizeHandling (str, optional): What WAF should do if the body is larger than WAF can inspect.
* Headers (Dict[str, Any], optional): Inspect the request headers. You must configure scope and pattern matching filters in the
Headers object, to define the set of headers to and the parts of the headers that WAF inspects.
Only the first 8 KB (8192 bytes) of a request's headers and only the first 200 headers are
forwarded to WAF for inspection by the underlying host service. You must configure how to handle
any oversize header content in the Headers object. WAF applies the pattern matching filters to
the headers that it receives from the underlying host service.
* MatchPattern (Dict[str, Any]): The filter to use to identify the subset of headers to inspect in a web request. You must
specify exactly one setting: either All, IncludedHeaders, or ExcludedHeaders. Example JSON:
"HeaderMatchPattern": { "ExcludedHeaders": {"KeyToExclude1", "KeyToExclude2"} }
* All (Dict, optional): Inspect all headers.
* IncludedHeaders (List[str], optional): Inspect only the headers that have a key that matches one of the strings specified here.
* ExcludedHeaders (List[str], optional): Inspect only the headers whose keys don't match any of the strings specified here.
* MatchScope (str): The parts of the headers to match with the rule inspection criteria. If you specify All, WAF
inspects both keys and values.
* OversizeHandling (str): What WAF should do if the headers of the request are larger than WAF can inspect.
* Cookies (Dict[str, Any], optional): Inspect the request cookies. You must configure scope and pattern matching filters in the
Cookies object, to define the set of cookies and the parts of the cookies that WAF inspects.
Only the first 8 KB (8192 bytes) of a request's cookies and only the first 200 cookies are
forwarded to WAF for inspection by the underlying host service. You must configure how to handle
any oversize cookie content in the Cookies object. WAF applies the pattern matching filters to
the cookies that it receives from the underlying host service.
* MatchPattern (Dict[str, Any]): The filter to use to identify the subset of cookies to inspect in a web request. You must
specify exactly one setting: either All, IncludedCookies, or ExcludedCookies. Example JSON:
"CookieMatchPattern": { "IncludedCookies": {"KeyToInclude1", "KeyToInclude2", "KeyToInclude3"} }
* All (Dict, optional): Inspect all cookies.
* IncludedCookies (List[str], optional): Inspect only the cookies that have a key that matches one of the strings specified here.
* ExcludedCookies (List[str], optional): Inspect only the cookies whose keys don't match any of the strings specified here.
* MatchScope (str): The parts of the cookies to inspect with the rule inspection criteria. If you specify All, WAF
inspects both keys and values.
* OversizeHandling (str): What WAF should do if the cookies of the request are larger than WAF can inspect.
* TextTransformations (List[Dict[str, Any]]): Text transformations eliminate some of the unusual formatting that attackers use in web requests
in an effort to bypass detection. If you specify one or more transformations in a rule
statement, 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.
* Priority (int): Sets the relative processing order for multiple transformations that are defined for a rule
statement. WAF processes all transformations, from lowest priority to highest, before inspecting
the transformed content. The priorities don't need to be consecutive, but they must all be
different.
* Type (str): You can specify the following transformation types:
BASE64_DECODE - Decode a Base64-encoded string.
BASE64_DECODE_EXT - Decode a Base64-encoded string, but use a forgiving implementation
that ignores characters that aren't valid.
CMD_LINE - Command-line transformations. These are helpful in reducing effectiveness of attackers who inject an operating system command-line
command and use unusual formatting to disguise some or all of the command.
* PositionalConstraint (str): The area within the portion of the web request that you want WAF to search for SearchString.
Valid values include the following: CONTAINS The specified part of the web request must
include the value of SearchString, but the location doesn't matter. CONTAINS_WORD The
specified part of the web request must include the value of SearchString, and SearchString must
contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition,
SearchString must be a word, which means that both of the following are true: SearchString is
at the beginning of the specified part of the web request or is preceded by a character other
than an alphanumeric character or underscore (_). Examples include the value of a header and
;BadBot. SearchString is at the end of the specified part of the web request or is followed
by a character other than an alphanumeric character or underscore (_), for example, BadBot; and
-BadBot;. EXACTLY The value of the specified part of the web request must exactly match the
value of SearchString. STARTS_WITH The value of SearchString must appear at the beginning of
the specified part of the web request. ENDS_WITH The value of SearchString must appear at the
end of the specified part of the web request.
* SqliMatchStatement (Dict[str, Any], optional): Attackers sometimes insert malicious SQL code into web requests in an effort to extract data
from your database. To allow or block web requests that appear to contain malicious SQL code,
create one or more SQL injection match conditions. An SQL injection match condition identifies
the part of web requests, such as the URI or the query string, that you want WAF to inspect.
Later in the process, when you create a web ACL, you specify whether to allow or block requests
that appear to contain malicious SQL code.
* FieldToMatch ('FieldToMatch'): The part of the web request that you want WAF to inspect. For more information, see
FieldToMatch.
* TextTransformations (List['TextTransformation']): Text transformations eliminate some of the unusual formatting that attackers use in web requests
in an effort to bypass detection. If you specify one or more transformations in a rule
statement, 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.
* XssMatchStatement (Dict[str, Any], optional): A rule statement that defines a cross-site scripting (XSS) match search for WAF to apply to web
requests. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a
vehicle to inject malicious client-site scripts into other legitimate web browsers. The XSS
match statement provides the location in requests that you want WAF to search and text
transformations to use on the search area before WAF searches for character sequences that are
likely to be malicious strings.
* FieldToMatch ('FieldToMatch'): The part of the web request that you want WAF to inspect. For more information, see
FieldToMatch.
* TextTransformations (List['TextTransformation']): Text transformations eliminate some of the unusual formatting that attackers use in web requests
in an effort to bypass detection. If you specify one or more transformations in a rule
statement, 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.
* SizeConstraintStatement (Dict[str, Any], optional): A rule statement that compares a number of bytes against the size of a request component, using
a comparison operator, such as greater than (>) or less than (<). For example, you can use a
size constraint statement to look for query strings that are longer than 100 bytes. If you
configure WAF to inspect the request body, WAF inspects only the first 8192 bytes (8 KB). If the
request body for your web requests never exceeds 8192 bytes, you can create a size constraint
condition and block requests that have a request body greater than 8192 bytes. 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.
* FieldToMatch ('FieldToMatch'): The part of the web request that you want WAF to inspect. For more information, see
FieldToMatch.
* ComparisonOperator (str): The operator to use to compare the request part to the size setting.
* Size (int): The size, in byte, to compare to the request part, after any transformations.
* TextTransformations (List['TextTransformation']): Text transformations eliminate some of the unusual formatting that attackers use in web requests
in an effort to bypass detection. If you specify one or more transformations in a rule
statement, 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.
* GeoMatchStatement (Dict[str, Any], optional): A rule statement used to identify web requests based on country of origin.
* CountryCodes (List[str], optional): An array of two-character country codes, for example, [ "US", "CN" ], from the alpha-2 country
ISO codes of the ISO 3166 international standard.
* ForwardedIPConfig (Dict[str, Any], optional): The configuration for inspecting IP addresses in an HTTP header that you specify, instead of
using the IP address that's reported by the web request origin. Commonly, this is the
X-Forwarded-For (XFF) header, but you can specify any header name. If the specified header
isn't present in the request, WAF doesn't apply the rule to the web request at all.
* HeaderName (str): The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For
(XFF) header, set this to X-Forwarded-For. If the specified header isn't present in the
request, WAF doesn't apply the rule to the web request at all.
* FallbackBehavior (str): The match status to assign to the web request if the request doesn't have a valid IP address in
the specified position. If the specified header isn't present in the request, WAF doesn't apply
the rule to the web request at all. You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
* RuleGroupReferenceStatement (Dict[str, Any], optional): A rule statement used to run the rules that are defined in a RuleGroup. To use this, create a
rule group with your rules, then provide the ARN of the rule group in this statement. You cannot
nest a RuleGroupReferenceStatement, for example for use inside a NotStatement or OrStatement.
You can only use a rule group reference statement at the top level inside a web ACL.
* ARN (str): The Amazon Resource Name (ARN) of the entity.
* ExcludedRules (List[Dict[str, Any]], optional): The rules in the referenced rule group whose actions are set to Count. When you exclude a rule,
WAF evaluates it exactly as it would if the rule action setting were Count. This is a useful
option for testing the rules in a rule group without modifying how they handle your web traffic.
* Name (str): The name of the rule whose action you want to override to Count.
* IPSetReferenceStatement (Dict[str, Any], optional): A rule statement used to detect web requests coming from particular IP addresses or address
ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use
the ARN of that set in this statement. To create an IP set, see CreateIPSet. Each IP set rule
statement references an IP set. You create and maintain the set independent of your rules. This
allows you to use the single set in multiple rules. When you update the referenced set, WAF
automatically updates all rules that reference it.
* ARN (str): The Amazon Resource Name (ARN) of the IPSet that this statement references.
* IPSetForwardedIPConfig (Dict[str, Any], optional): The configuration for inspecting IP addresses in an HTTP header that you specify, instead of
using the IP address that's reported by the web request origin. Commonly, this is the
X-Forwarded-For (XFF) header, but you can specify any header name. If the specified header
isn't present in the request, WAF doesn't apply the rule to the web request at all.
* HeaderName (str): The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For
(XFF) header, set this to X-Forwarded-For. If the specified header isn't present in the
request, WAF doesn't apply the rule to the web request at all.
* FallbackBehavior (str): The match status to assign to the web request if the request doesn't have a valid IP address in
the specified position. If the specified header isn't present in the request, WAF doesn't apply
the rule to the web request at all. You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
* Position (str): The position in the header to search for the IP address. The header can contain IP addresses of
the original client and also of proxies. For example, the header value could be 10.1.1.1,
127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest
identify proxies that the request went through. The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually
the client's original IP. LAST - Inspect the last IP address in the list of IP addresses in
the header. ANY - Inspect all IP addresses in the header for a match. If the header contains
more than 10 IP addresses, WAF inspects the last 10.
* RegexPatternSetReferenceStatement (Dict[str, Any], optional): A rule statement used to search web request components for matches with regular expressions. To
use this, create a RegexPatternSet that specifies the expressions that you want to detect, then
use the ARN of that set in this statement. A web request matches the pattern set rule statement
if the request component matches any of the patterns in the set. To create a regex pattern set,
see CreateRegexPatternSet. Each regex pattern set rule statement references a regex pattern set.
You create and maintain the set independent of your rules. This allows you to use the single set
in multiple rules. When you update the referenced set, WAF automatically updates all rules that
reference it.
* ARN (str): The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
* FieldToMatch ('FieldToMatch'): The part of the web request that you want WAF to inspect. For more information, see
FieldToMatch.
* TextTransformations (List['TextTransformation']): Text transformations eliminate some of the unusual formatting that attackers use in web requests
in an effort to bypass detection. If you specify one or more transformations in a rule
statement, 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.
* RateBasedStatement (Dict[str, Any], optional): A rate-based rule tracks the rate of requests for each originating IP address, and triggers the
rule action when the rate exceeds a limit that you specify on the number of requests in any
5-minute time span. You can use this to put a temporary block on requests from an IP address
that is sending excessive requests. WAF tracks and manages web requests separately for each
instance of a rate-based rule that you use. For example, if you provide the same rate-based rule
settings in two web ACLs, each of the two rule statements represents a separate instance of the
rate-based rule and gets its own tracking and management by WAF. If you define a rate-based rule
inside a rule group, and then use that rule group in multiple places, each use creates a
separate instance of the rate-based rule that gets its own tracking and management by WAF. When
the rule action triggers, WAF blocks additional requests from the IP address until the request
rate falls below the limit. You can optionally nest another statement inside the rate-based
statement, to narrow the scope of the rule so that it only counts requests that match the nested
statement. For example, based on recent requests that you have seen from an attacker, you might
create a rate-based rule with a nested AND rule statement that contains the following nested
statements: An IP match statement with an IP set that specified the address 192.0.2.44. A
string match statement that searches in the User-Agent header for the string BadBot. In this
rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000.
Requests that meet both of the conditions in the statements are counted. If the count exceeds
1,000 requests per five minutes, the rule action triggers. Requests that do not meet both
conditions are not counted towards the rate limit and are not affected by this rule. You cannot
nest a RateBasedStatement inside another statement, for example inside a NotStatement or
OrStatement. You can define a RateBasedStatement inside a web ACL and inside a rule group.
* Limit (int): The limit on requests per 5-minute period for a single originating IP address. If the statement
includes a ScopeDownStatement, this limit is applied only to the requests that match the
statement.
* AggregateKeyType (str): Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this,
configure the ForwardedIPConfig, to specify the header to use.
* ScopeDownStatement ('Statement', optional): An optional nested statement that narrows the scope of the web requests that are evaluated by
the rate-based statement. Requests are only tracked by the rate-based statement if they match
the scope-down statement. You can use any nestable Statement in the scope-down statement, and
you can nest statements at any level, the same as you can for a rule statement.
* ForwardedIPConfig ('ForwardedIPConfig', optional): The configuration for inspecting IP addresses in an HTTP header that you specify, instead of
using the IP address that's reported by the web request origin. Commonly, this is the
X-Forwarded-For (XFF) header, but you can specify any header name. If the specified header
isn't present in the request, WAF doesn't apply the rule to the web request at all. This is
required if AggregateKeyType is set to FORWARDED_IP.
* AndStatement (Dict[str, Any], optional): A logical rule statement used to combine other rule statements with AND logic. You provide more
than one Statement within the AndStatement.
* Statements (List[Dict[str, Any]]): The statements to combine with AND logic. You can use any statements that can be nested.
* ByteMatchStatement ('ByteMatchStatement', optional): A rule statement that defines a string match search for WAF to apply to web requests. The byte
match statement provides the bytes to search for, the location in requests that you want WAF to
search, and other settings. The bytes to search for are typically a string that corresponds with
ASCII characters. In the WAF console and the developer guide, this is refered to as a string
match statement.
* SqliMatchStatement ('SqliMatchStatement', optional): Attackers sometimes insert malicious SQL code into web requests in an effort to extract data
from your database. To allow or block web requests that appear to contain malicious SQL code,
create one or more SQL injection match conditions. An SQL injection match condition identifies
the part of web requests, such as the URI or the query string, that you want WAF to inspect.
Later in the process, when you create a web ACL, you specify whether to allow or block requests
that appear to contain malicious SQL code.
* XssMatchStatement ('XssMatchStatement', optional): A rule statement that defines a cross-site scripting (XSS) match search for WAF to apply to web
requests. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a
vehicle to inject malicious client-site scripts into other legitimate web browsers. The XSS
match statement provides the location in requests that you want WAF to search and text
transformations to use on the search area before WAF searches for character sequences that are
likely to be malicious strings.
* SizeConstraintStatement ('SizeConstraintStatement', optional): A rule statement that compares a number of bytes against the size of a request component, using
a comparison operator, such as greater than (>) or less than (<). For example, you can use a
size constraint statement to look for query strings that are longer than 100 bytes. If you
configure WAF to inspect the request body, WAF inspects only the first 8192 bytes (8 KB). If the
request body for your web requests never exceeds 8192 bytes, you can create a size constraint
condition and block requests that have a request body greater than 8192 bytes. 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.
* GeoMatchStatement ('GeoMatchStatement', optional): A rule statement used to identify web requests based on country of origin.
* RuleGroupReferenceStatement ('RuleGroupReferenceStatement', optional): A rule statement used to run the rules that are defined in a RuleGroup. To use this, create a
rule group with your rules, then provide the ARN of the rule group in this statement. You cannot
nest a RuleGroupReferenceStatement, for example for use inside a NotStatement or OrStatement.
You can only use a rule group reference statement at the top level inside a web ACL.
* IPSetReferenceStatement ('IPSetReferenceStatement', optional): A rule statement used to detect web requests coming from particular IP addresses or address
ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use
the ARN of that set in this statement. To create an IP set, see CreateIPSet. Each IP set rule
statement references an IP set. You create and maintain the set independent of your rules. This
allows you to use the single set in multiple rules. When you update the referenced set, WAF
automatically updates all rules that reference it.
* RegexPatternSetReferenceStatement ('RegexPatternSetReferenceStatement', optional): A rule statement used to search web request components for matches with regular expressions. To
use this, create a RegexPatternSet that specifies the expressions that you want to detect, then
use the ARN of that set in this statement. A web request matches the pattern set rule statement
if the request component matches any of the patterns in the set. To create a regex pattern set,
see CreateRegexPatternSet. Each regex pattern set rule statement references a regex pattern set.
You create and maintain the set independent of your rules. This allows you to use the single set
in multiple rules. When you update the referenced set, WAF automatically updates all rules that
reference it.
* RateBasedStatement ('RateBasedStatement', optional): A rate-based rule tracks the rate of requests for each originating IP address, and triggers the
rule action when the rate exceeds a limit that you specify on the number of requests in any
5-minute time span. You can use this to put a temporary block on requests from an IP address
that is sending excessive requests. WAF tracks and manages web requests separately for each
instance of a rate-based rule that you use. For example, if you provide the same rate-based rule
settings in two web ACLs, each of the two rule statements represents a separate instance of the
rate-based rule and gets its own tracking and management by WAF. If you define a rate-based rule
inside a rule group, and then use that rule group in multiple places, each use creates a
separate instance of the rate-based rule that gets its own tracking and management by WAF. When
the rule action triggers, WAF blocks additional requests from the IP address until the request
rate falls below the limit. You can optionally nest another statement inside the rate-based
statement, to narrow the scope of the rule so that it only counts requests that match the nested
statement. For example, based on recent requests that you have seen from an attacker, you might
create a rate-based rule with a nested AND rule statement that contains the following nested
statements: An IP match statement with an IP set that specified the address 192.0.2.44. A
string match statement that searches in the User-Agent header for the string BadBot. In this
rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000.
Requests that meet both of the conditions in the statements are counted. If the count exceeds
1,000 requests per five minutes, the rule action triggers. Requests that do not meet both
conditions are not counted towards the rate limit and are not affected by this rule. You cannot
nest a RateBasedStatement inside another statement, for example inside a NotStatement or
OrStatement. You can define a RateBasedStatement inside a web ACL and inside a rule group.
* AndStatement ('AndStatement', optional): A logical rule statement used to combine other rule statements with AND logic. You provide more
than one Statement within the AndStatement.
* OrStatement (Dict[str, Any], optional): A logical rule statement used to combine other rule statements with OR logic. You provide more
than one Statement within the OrStatement.
* Statements (List['Statement']): The statements to combine with OR logic. You can use any statements that can be nested.
* NotStatement (Dict[str, Any], optional): A logical rule statement used to negate the results of another rule statement. You provide one
Statement within the NotStatement.
* Statement ('Statement'): The statement to negate. You can use any statement that can be nested.
* ManagedRuleGroupStatement (Dict[str, Any], optional): A rule statement used to run the rules that are defined in a managed rule group. To use this,
provide the vendor name and the name of the rule group in this statement. You can retrieve the
required names by calling ListAvailableManagedRuleGroups. You cannot nest a
ManagedRuleGroupStatement, for example for use inside a NotStatement or OrStatement. It can only
be referenced as a top-level statement within a rule.
* VendorName (str): The name of the managed rule group vendor. You use this, along with the rule group name, to
identify the rule group.
* Name (str): The name of the managed rule group. You use this, along with the vendor name, to identify the
rule group.
* Version (str, optional): The version of the managed rule group to use. If you specify this, the version setting is fixed
until you change it. If you don't specify this, WAF uses the vendor's default version, and then
keeps the version at the vendor's default when the vendor updates the managed rule group
settings.
* ExcludedRules (List['ExcludedRule'], optional): The rules in the referenced rule group whose actions are set to Count. When you exclude a rule,
WAF evaluates it exactly as it would if the rule action setting were Count. This is a useful
option for testing the rules in a rule group without modifying how they handle your web traffic.
* ScopeDownStatement ('Statement', optional): An optional nested statement that narrows the scope of the web requests that are evaluated by
the managed rule group. Requests are only evaluated by the rule group if they match the scope-
down statement. You can use any nestable Statement in the scope-down statement, and you can nest
statements at any level, the same as you can for a rule statement.
* ManagedRuleGroupConfigs (List[Dict[str, Any]], optional): Additional information that's used by a managed rule group. Most managed rule groups don't
require this. Use this for the account takeover prevention managed rule group
AWSManagedRulesATPRuleSet, to provide information about the sign-in page of your application.
You can provide multiple individual ManagedRuleGroupConfig objects for any rule group
configuration, for example UsernameField and PasswordField. The configuration that you provide
depends on the needs of the managed rule group. For the ATP managed rule group, you provide the
following individual configuration objects: LoginPath, PasswordField, PayloadType and
UsernameField.
* LoginPath (str, optional): The path of the login endpoint for your application. For example, for the URL
https://example.com/web/login, you would provide the path /web/login.
* PayloadType (str, optional): The payload type for your login endpoint, either JSON or form encoded.
* UsernameField (Dict[str, Any], optional): Details about your login page username field.
* Identifier (str): The name of the username field. For example /form/username.
* PasswordField (Dict[str, Any], optional): Details about your login page password field.
* Identifier (str): The name of the password field. For example /form/password.
* LabelMatchStatement (Dict[str, Any], optional): A rule statement that defines a string match search against labels that have been added to the
web request by rules that have already run in the web ACL. The label match statement provides
the label or namespace string to search for. The label string can represent a part or all of the
fully qualified label name that had been added to the web request. Fully qualified labels have a
prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL
context of the rule that added the label. If you do not provide the fully qualified name in your
label match string, WAF performs the search for labels that were added in the same context as
the label match statement.
* Scope (str): Specify whether you want to match using the label name or just the namespace.
* Key (str): The string to match against. The setting you provide for this depends on the match statement's
Scope setting: If the Scope indicates LABEL, then this specification must include the name
and can include any number of preceding namespace specifications and prefix up to providing the
fully qualified label name. If the Scope indicates NAMESPACE, then this specification can
include any number of contiguous namespace strings, and can include the entire label namespace
prefix from the rule group or web ACL where the label originates. Labels are case sensitive
and components of a label must be separated by colon, for example NS1:NS2:name.
* RegexMatchStatement (Dict[str, Any], optional): A rule statement used to search web request components for a match against a single regular
expression.
* RegexString (str): The string representing the regular expression.
* FieldToMatch ('FieldToMatch'): The part of the web request that you want WAF to inspect. For more information, see
FieldToMatch.
* TextTransformations (List['TextTransformation']): Text transformations eliminate some of the unusual formatting that attackers use in web requests
in an effort to bypass detection. If you specify one or more transformations in a rule
statement, 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.
* OrStatement ('OrStatement', optional): A logical rule statement used to combine other rule statements with OR logic. You provide more
than one Statement within the OrStatement.
* NotStatement ('NotStatement', optional): A logical rule statement used to negate the results of another rule statement. You provide one
Statement within the NotStatement.
* ManagedRuleGroupStatement ('ManagedRuleGroupStatement', optional): A rule statement used to run the rules that are defined in a managed rule group. To use this,
provide the vendor name and the name of the rule group in this statement. You can retrieve the
required names by calling ListAvailableManagedRuleGroups. You cannot nest a
ManagedRuleGroupStatement, for example for use inside a NotStatement or OrStatement. It can only
be referenced as a top-level statement within a rule.
* LabelMatchStatement ('LabelMatchStatement', optional): A rule statement that defines a string match search against labels that have been added to the
web request by rules that have already run in the web ACL. The label match statement provides
the label or namespace string to search for. The label string can represent a part or all of the
fully qualified label name that had been added to the web request. Fully qualified labels have a
prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL
context of the rule that added the label. If you do not provide the fully qualified name in your
label match string, WAF performs the search for labels that were added in the same context as
the label match statement.
* RegexMatchStatement ('RegexMatchStatement', optional): A rule statement used to search web request components for a match against a single regular
expression.
* Action (Dict[str, Any], optional): The action that WAF should take on a web request when it matches the rule statement. Settings at
the web ACL level can override the rule action setting. This is used only for rules whose
statements do not reference a rule group. Rule statements that reference a rule group include
RuleGroupReferenceStatement and ManagedRuleGroupStatement. You must specify either this Action
setting or the rule OverrideAction setting, but not both: If the rule statement does not
reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this
action setting.
* Block (Dict[str, Any], optional): Instructs WAF to block the web request.
* CustomResponse (Dict[str, Any], optional): Defines a custom response for the web request. For information about customizing web requests
and responses, see Customizing web requests and responses in WAF in the WAF Developer Guide.
* ResponseCode (int): The HTTP status code to return to the client. For a list of status codes that you can use in
your custom reqponses, see Supported status codes for custom response in the WAF Developer
Guide.
* CustomResponseBodyKey (str, optional): References the response body that you want WAF to return to the web request client. You can
define a custom response for a rule action or a default web ACL action that is set to block. To
do this, you first define the response body key and value in the CustomResponseBodies setting
for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL
default action BlockAction setting, you reference the response body using this key.
* ResponseHeaders (List[Dict[str, Any]], optional): The HTTP headers to use in the response. Duplicate header names are not allowed. For
information about the limits on count and size for custom request and response settings, see WAF
quotas in the WAF Developer Guide.
* Name (str): The name of the custom header. For custom request header insertion, when WAF inserts the header
into the request, it prefixes this name x-amzn-waf-, to avoid confusion with the headers that
are already in the request. For example, for the header name sample, WAF inserts the header
x-amzn-waf-sample.
* Value (str): The value of the custom header.
* Allow (Dict[str, Any], optional): Instructs WAF to allow the web request.
* CustomRequestHandling (Dict[str, Any], optional): Defines custom handling for the web request. For information about customizing web requests and
responses, see Customizing web requests and responses in WAF in the WAF Developer Guide.
* InsertHeaders (List['CustomHTTPHeader']): The HTTP headers to insert into the request. Duplicate header names are not allowed. For
information about the limits on count and size for custom request and response settings, see WAF
quotas in the WAF Developer Guide.
* Count (Dict[str, Any], optional): Instructs WAF to count the web request and allow it.
* CustomRequestHandling ('CustomRequestHandling', optional): Defines custom handling for the web request. For information about customizing web requests and
responses, see Customizing web requests and responses in WAF in the WAF Developer Guide.
* Captcha (Dict[str, Any], optional): Instructs WAF to run a CAPTCHA check against the web request.
* CustomRequestHandling ('CustomRequestHandling', optional): Defines custom handling for the web request. For information about customizing web requests and
responses, see Customizing web requests and responses in WAF in the WAF Developer Guide.
* OverrideAction (Dict[str, Any], optional): The action to use in the place of the action that results from the rule group evaluation. Set
the override action to none to leave the result of the rule group alone. Set it to count to
override the result to count only. You can only use this for rule statements that reference a
rule group, like RuleGroupReferenceStatement and ManagedRuleGroupStatement. This option is
usually set to none. It does not affect how the rules in the rule group are evaluated. If you
want the rules in the rule group to only count matches, do not use this and instead exclude
those rules in your rule group reference statement settings.
* Count ('CountAction', optional): Override the rule group evaluation result to count only. This option is usually set to none.
It does not affect how the rules in the rule group are evaluated. If you want the rules in the
rule group to only count matches, do not use this and instead exclude those rules in your rule
group reference statement settings.
* None (Dict, optional): Don't override the rule group evaluation result. This is the most common setting.
* RuleLabels (List[Dict[str, Any]], optional): Labels to apply to web requests that match the rule match statement. WAF applies fully qualified
labels to matching web requests. A fully qualified label is the concatenation of a label
namespace and a rule label. The rule's rule group or web ACL defines the label namespace. Rules
that run after this rule in the web ACL can match against these labels using a
LabelMatchStatement. For each label, provide a case-sensitive string containing optional
namespaces and a label name, according to the following guidelines: Separate each component of
the label with a colon. Each namespace or name can have up to 128 characters. You can
specify up to 5 namespaces in a label. Don't use the following reserved words in your label
specification: aws, waf, managed, rulegroup, webacl, regexpatternset, or ipset. For example,
myLabelName or nameSpace1:nameSpace2:myLabelName.
* Name (str): The label string.
* VisibilityConfig (Dict[str, Any]): Defines and enables Amazon CloudWatch metrics and web request sample collection.
* SampledRequestsEnabled (bool): A boolean indicating whether WAF should store a sampling of the web requests that match the
rules. You can view the sampled requests through the WAF console.
* CloudWatchMetricsEnabled (bool): A boolean indicating whether the associated resource sends metrics to Amazon CloudWatch. For the
list of available metrics, see WAF Metrics.
* MetricName (str): A name of the Amazon CloudWatch metric. The name can contain only the characters: A-Z, a-z, 0-9,
- (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can't
contain whitespace or metric names reserved for WAF, for example "All" and "Default_Action."
* CaptchaConfig (Dict[str, Any], optional): Specifies how WAF should handle CAPTCHA evaluations. If you don't specify this, WAF uses the
CAPTCHA configuration that's defined for the web ACL.
* ImmunityTimeProperty (Dict[str, Any], optional): Determines how long a CAPTCHA token remains valid after the client successfully solves a CAPTCHA
puzzle.
* ImmunityTime (int): The amount of time, in seconds, that a CAPTCHA token is valid. The default setting is 300.
custom_response_bodies(dict, optional): A map of custom response keys and content bodies. When you create a rule with a
block action, you can send a custom response to the web request. You define these for the web ACL, and then
use them in the rules and default actions that you define in the web ACL.
captcha_config(dict, optional): Specifies how WAF should handle CAPTCHA evaluations for rules that don't have their own
CaptchaConfig settings. If you don't specify this, WAF uses its default settings for CaptchaConfig.
* ImmunityTimeProperty (dict) -- Determines how long a CAPTCHA token remains valid after the client
successfully solves a CAPTCHA puzzle.
* ImmunityTime(integer) -- The amount of time, in seconds, that a CAPTCHA token is valid. The default
setting is 300.
tags(list, optional): A tag associated with an Amazon Web Services resource. Tags are key:value pairs that you can use to
categorize and manage your resources, for purposes like billing or other management. Typically, the tag key
represents a category, such as "environment", and the tag value represents a specific value within that
category, such as "test," "development," or "production". Or you might set the tag key to "customer" and
the value to the customer name or ID. You can specify one or more tags to add to each Amazon Web Services
resource, up to 50 tags for a resource.
list of tags in the format of [{"Key": tag-key, "Value": tag-value}] or dict in the format of
{tag-key: tag-value}
