AWS::NetworkFirewall::FirewallPolicy StatefulRuleGroupReference

Identifier for a single stateful rule group, used in a firewall policy to refer to a rule group.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{
  "Override" : StatefulRuleGroupOverride,
  "Priority" : Integer,
  "ResourceArn" : String
}

Properties

Override

The action that allows the policy owner to override the behavior of the rule group within a policy.

Required: No

Type: StatefulRuleGroupOverride

Update requires: No interruption

Priority

An integer setting that indicates the order in which to run the stateful rule groups in a single AWS::NetworkFirewall::FirewallPolicy. This setting only applies to firewall policies that specify the STRICT_ORDER rule order in the stateful engine options settings.

Network Firewall evalutes each stateful rule group against a packet starting with the group that has the lowest priority setting. You must ensure that the priority settings are unique within each policy.

You can change the priority settings of your rule groups at any time. To make it easier to insert rule groups later, number them so there's a wide range in between, for example use 100, 200, and so on.

ResourceArn

The Amazon Resource Name (ARN) of the stateful rule group.
