NAME
Paws::WAFv2::RateBasedStatement
USAGE
This class represents one of two things:
Arguments in a call to a service
Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.
As an example, if Att1 is expected to be a Paws::WAFv2::RateBasedStatement object:
$service_obj->Method(Att1 => { AggregateKeyType => $value, ..., ScopeDownStatement => $value });Results returned from an API call
Use accessors for each attribute. If Att1 is expected to be an Paws::WAFv2::RateBasedStatement object:
$result = $service_obj->Method(...);
$result->Att1->AggregateKeyTypeDESCRIPTION
This is the latest version of AWS WAF, named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html).
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.
When the rule action triggers, AWS 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, for example for use inside a NotStatement or OrStatement. It can only be referenced as a top-level statement within a rule.
ATTRIBUTES
REQUIRED AggregateKeyType => Str
Setting that indicates how to aggregate the request counts. Currently, you must set this to IP. The request counts are aggregated on IP addresses.
REQUIRED Limit => Int
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopDownStatement, this limit is applied only to the requests that match the statement.
ScopeDownStatement => Paws::WAFv2::Statement
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
