Using tag-based resource groups in Network Firewall
Use tag-based resource groups to ensure that your rules stay in sync as your AWS resources change. A tag-based resource group is a collection of AWS resources, grouped by tags, that you can reference in an Network Firewall stateful rule group. A tag is a label that you assign to an AWS resource. As you add, delete, and modify your resources belonging to the resource group, Network Firewall automatically updates your rules with the IPs of the resources in the resource group. For information about referencing resource groups in rule groups, see IP set references in Suricata compatible AWS Network Firewall rule groups.
