-- | Configures one or more IP set references for a Suricata-compatible rule
-- group. This is used in CreateRuleGroup or UpdateRuleGroup. An IP set
-- reference is a rule variable that references a resource that you create
-- and manage in another Amazon Web Services service, such as an Amazon VPC
-- prefix list. Network Firewall IP set references enable you to
-- dynamically update the contents of your rules. When you create, update,
-- or delete the IP set you are referencing in your rule, Network Firewall
-- automatically updates the rule\'s content with the changes. For more
-- information about IP set references in Network Firewall, see
-- <https://docs.aws.amazon.com/network-firewall/latest/developerguide/rule-groups-ip-set-references Using IP set references>
-- in the /Network Firewall Developer Guide/.
--
-- Network Firewall currently supports only
-- <https://docs.aws.amazon.com/vpc/latest/userguide/managed-prefix-lists.html Amazon VPC prefix lists>
-- as IP set references.
