Author local rulestacks when you're assigned the LocalRuleStackAdmin role.
In the Cloud NGFW tenant, you can author rulestacks if you're you assigned the
LocalRuleStackAdmin or GlobalRulestackAdmin role. To author a global rulestack, you
must have used the AWS Firewall Manager to create your Cloud NGFW tenant.
When you create a local rulestack, you must specify an AWS account. The rulestack is applied to
NGFWs associated with that AWS account only. Complete the following procedure to
create a rulestack.
