New-VSWAFRegionalRateBasedRule

New-VSWAFRegionalRateBasedRule

SYNOPSIS

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

DESCRIPTION

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

  • The requests come from 192.0.2.44.

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

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

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

PARAMETERS

-LogicalId

The logical ID must be alphanumeric (A-Za-z0-9) and unique within the template. Use the logical name to reference the resource in other parts of the template. For example, if you want to map an Amazon Elastic Block Store volume to an Amazon EC2 instance, you reference the logical IDs to associate the block stores with the instance.

Type: String
Parameter Sets: (All)
Aliases:

Required: True
Position: 1
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-MetricName

A friendly name or description for the metrics for a RateBasedRule. The name can contain only alphanumeric characters A-Z, a-z, 0-9, with maximum length 128 and minimum length one. It can’t contain whitespace or metric names reserved for AWS WAF, including “All” and “Default_Action.” You can’t change the name of the metric after you create the RateBasedRule.

-RateLimit

The maximum number of requests, which have an identical value in the field specified by the RateKey, allowed in a five-minute period. If the number of requests exceeds the RateLimit and the other predicates specified in the rule are also met, AWS WAF triggers the action that is specified for this rule.

-MatchPredicates

The Predicates object contains one Predicate element for each ByteMatchSet, IPSet, or SqlInjectionMatchSet> object that you want to include in a RateBasedRule.

Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-RateKey

The field that AWS WAF uses to determine if requests are likely arriving from single source and thus subject to rate monitoring. The only valid value for RateKey is IP. IP indicates that requests arriving from the same IP address are subject to the RateLimit that is specified in the RateBasedRule.

-Name

A friendly name or description for a RateBasedRule. You can’t change the name of a RateBasedRule after you create it.

Aliases:

Required: True
Position: Named
Default value: None

Accept wildcard characters: False

-DeletionPolicy

With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted. You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy attribute, AWS CloudFormation deletes the resource by default.

To keep a resource when its stack is deleted, specify Retain for that resource. You can use retain for any resource. For example, you can retain a nested stack, S3 bucket, or EC2 instance so that you can continue to use or modify those resources after you delete their stacks.

You must use one of the following options: “Delete”,”Retain”,”Snapshot”

Type: String
Parameter Sets: (All)
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-DependsOn

With the DependsOn attribute you can specify that the creation of a specific resource follows another. When you add a DependsOn attribute to a resource, that resource is created only after the creation of the resource specified in the DependsOn attribute.

This parameter takes a string or list of strings representing Logical IDs of resources that must be created prior to this resource being created.

Type: String[]
Parameter Sets: (All)
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Metadata

The Metadata attribute enables you to associate structured data with a resource. By adding a Metadata attribute to a resource, you can add data in JSON or YAML to the resource declaration. In addition, you can use intrinsic functions (such as GetAtt and Ref), parameters, and pseudo parameters within the Metadata attribute to add those interpreted values.

You must use a PSCustomObject containing key/value pairs here. This will be returned when describing the resource using AWS CLI.

Type: Object
Parameter Sets: (All)
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-UpdatePolicy

Use the UpdatePolicy attribute to specify how AWS CloudFormation handles updates to the AWS::AutoScaling::AutoScalingGroup resource. AWS CloudFormation invokes one of three update policies depending on the type of change you make or whether a scheduled action is associated with the Auto Scaling group.

You must use the “Add-UpdatePolicy” function here.

Type: Object
Parameter Sets: (All)
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Condition

Logical ID of the condition that this resource needs to be true in order for this resource to be provisioned.

Type: Object
Parameter Sets: (All)
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.
