listFirewallRuleTypes
Retrieves the rule-type variants that can be used in the FirewallRuleType field of CreateFirewallRule and UpdateFirewallRule. Each returned FirewallRuleTypeDefinition identifies one variant + value combination — for example, FirewallAdvancedContentCategory + VIOLENCE_AND_HATE_SPEECH, or PartnerThreatProtection + a partner-managed feed.
The supported RuleType filter values are FirewallAdvancedContentCategory, FirewallAdvancedThreatCategory, DnsThreatProtection, and PartnerThreatProtection. When a returned definition's variant requires an external subscription (currently only PartnerThreatProtection), the response also includes a SubscriptionInfo identifying the AWS Marketplace product that backs it; absence of SubscriptionInfo means the variant is fully managed by AWS and requires no separate subscription.
