Configuration templates to create AWS Network Firewall related settings including Firewall endpoints, Firewall Rule Policies, and Firewall Rule Groups (Stateful and Stateless) used to deploy network protections for VPC resources by enforcing traffic flows, filtering URLs, and inspecting traffic for vulnerabilities using IPS signatures.

The following resources are available for configuration:

  • Firewall – defines the configuration settings for an AWS Network Firewall firewall, which include the firewall policy and the subnets in your VPC to use for the firewall endpoints.
  • Firewall Policy: defines a collection of stateless and stateful network traffic filtering rule groups which can then be associated with a firewall
  • Rule Groups – Reusable set of criteria for inspecting and handling network traffic. There are two types of rule groups:
    • Stateless – Defines standard, 5-tuple criteria for examining a packet on its own, with no additional context.
    • Stateful – Defines criteria for examining a packet in the context of traffic flow and of other traffic that's related to the packet. Stateful rule groups are available in the following categories:
      • 5-tuple – Defines standard criteria for examining a packet within the context of a traffic workflow.
      • Domain list – Defines a list of domain names and specifies the protocol type to inspect.
      • Suricata compatible IPS rules – Defines intrusion prevention system (IPS) rules in the rule group, in Suricata compatible format. (Currently not supported)
