Options for stateful rules in Network Firewall
A stateful rule group is a rule group that uses Suricata compatible intrusion prevention system (IPS) specifications. Suricata is an open source network IPS that includes a standard rule-based language for stateful network traffic inspection.
When you create a Network Firewall stateful rule group from Suricata compatible rules, you can provide the rules to the rule group creation operation in one of the following ways:
Standard, simple rule group specification – With this option, Network Firewall translates your specification into Suricata compatible rules and then passes the resulting rule strings to Suricata for processing.
Domain list rule specification – With this option, Network Firewall translates your rule specification into Suricata compatible rules and then passes the resulting rule strings to Suricata for processing.
Rule strings that are written in Suricata compatible syntax – When you use this option, Network Firewall passes your rule strings to Suricata for processing.
The sections that follow provide details for each of these options.
