Creates an Network Firewall Firewall and accompanying FirewallStatus for a VPC.

The firewall defines the configuration settings for an Network Firewall firewall. The settings that you can define at creation include the firewall policy, the subnets in your VPC to use for the firewall endpoints, and any tags that are attached to the firewall Amazon Web Services resource.

After you create a firewall, you can provide additional settings, like the logging configuration.

To update the settings for a firewall, you use the operations that apply to the settings themselves, for example UpdateLoggingConfiguration, AssociateSubnets, and UpdateFirewallDeleteProtection.

To manage a firewall's tags, use the standard Amazon Web Services resource tagging operations, ListTagsForResource, TagResource, and UntagResource.

The types of rule configurations that Network Firewall analyzes your rule groups for. Network Firewall analyzes stateless rule groups for the following types of rule configurations:

- `STATELESS_RULE_FORWARDING_ASYMMETRICALLY`

  Cause: One or more stateless rules with the action `pass` or `forward` are forwarding traffic asymmetrically. Specifically, the rule's set of source IP addresses or their associated port numbers, don't match the set of destination IP addresses or their associated port numbers.

  To mitigate: Make sure that there's an existing return path. For example, if the rule allows traffic from source 10.1.0.0/24 to destination 20.1.0.0/24, you should allow return traffic from source 20.1.0.0/24 to destination 10.1.0.0/24.

- `STATELESS_RULE_CONTAINS_TCP_FLAGS`

  Cause: At least one stateless rule with the action `pass` or`forward` contains TCP flags that are inconsistent in the forward and return directions.

  To mitigate: Prevent asymmetric routing issues caused by TCP flags by following these actions:

  - Remove unnecessary TCP flag inspections from the rules.

  - If you need to inspect TCP flags, check that the rules correctly account for changes in TCP flags throughout the TCP connection cycle, for example `SYN` and `ACK` flags used in a 3-way TCP handshake.

To make a conditional change to the firewall, provide the token in your update request. Network Firewall uses the token to ensure that the firewall hasn't changed since you last retrieved it. If it has changed, the operation fails with an `InvalidTokenException`. If this happens, retrieve the firewall again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.

The maximum operating resources that this rule group can use. Rule group capacity is fixed at creation. When you update a rule group, you are limited to this capacity. When you reference a rule group from a firewall policy, Network Firewall reserves this capacity for the rule group.

You can retrieve the capacity that would be required for a rule group before you create the rule group by calling CreateRuleGroup with `DryRun` set to `TRUE`.

You can't change or exceed this capacity when you update the rule group, so leave room for your rule group to grow.

Capacity for a stateless rule group

For a stateless rule group, the capacity required is the sum of the capacity requirements of the individual rules that you expect to have in the rule group.

To calculate the capacity requirement of a single rule, multiply the capacity requirement values of each of the rule's match settings:

- A match setting with no criteria specified has a value of 1.

- A match setting with `Any` specified has a value of 1.

- All other match settings have a value equal to the number of elements provided in the setting. For example, a protocol setting [\"UDP\"] and a source setting [\"10.0.0.0/24\"] each have a value of 1. A protocol setting [\"UDP\",\"TCP\"] has a value of 2. A source setting [\"10.0.0.0/24\",\"10.0.0.1/24\",\"10.0.0.2/24\"] has a value of 3.

A rule with no criteria specified in any of its match settings has a capacity requirement of 1. A rule with protocol setting [\"UDP\",\"TCP\"], source setting [\"10.0.0.0/24\",\"10.0.0.1/24\",\"10.0.0.2/24\"], and a single specification or no specification for each of the other match settings has a capacity requirement of 6.

Capacity for a stateful rule group

For a stateful rule group, the minimum capacity required is the number of individual rules that you expect to have in the rule group.

The default action for this rule order is `PASS`, followed by `DROP`, `REJECT`, and `ALERT` actions. Stateful rules are provided to the rule engine as Suricata compatible strings, and Suricata evaluates them based on your settings. For more information, see Evaluation order for stateful rules in the Network Firewall Developer Guide.

" }, "StreamExceptionPolicy":{ "shape":"StreamExceptionPolicy", "documentation":"

Configures how Network Firewall processes traffic when a network connection breaks midstream. Network connections can break due to disruptions in external networks or within the firewall itself.

- `DROP` - Network Firewall fails closed and drops all subsequent traffic going to the firewall. This is the default behavior.

- `CONTINUE` - Network Firewall continues to apply rules to the subsequent traffic without context from traffic before the break. This impacts the behavior of rules that depend on this context. For example, if you have a stateful rule to `drop http` traffic, Network Firewall won't match the traffic for this rule because the service won't have the context from session initialization defining the application layer protocol as HTTP. However, this behavior is rule dependent—a TCP-layer rule using a `flow:stateless` rule would still match, as would the `aws:drop_strict` default action.

- `REJECT` - Network Firewall fails closed and drops all subsequent traffic going to the firewall. Network Firewall also sends a TCP reject packet back to your client so that the client can immediately establish a new session. Network Firewall will have context about the new session and will apply rules to the subsequent traffic.

This is the API Reference for Network Firewall. This guide is for developers who need detailed information about the Network Firewall API actions, data types, and errors.

- The REST API requires you to handle connection details, such as calculating signatures, handling request retries, and error handling. For general information about using the Amazon Web Services REST APIs, see Amazon Web Services APIs.

  To access Network Firewall using the REST API endpoint: `https://network-firewall.<region>.amazonaws.com`

- Alternatively, you can use one of the Amazon Web Services SDKs to access an API that's tailored to the programming language or platform that you're using. For more information, see Amazon Web Services SDKs.

- For descriptions of Network Firewall features, including and step-by-step instructions on how to use them through the Network Firewall console, see the Network Firewall Developer Guide.

Network Firewall is a stateful, managed, network firewall and intrusion detection and prevention service for Amazon Virtual Private Cloud (Amazon VPC). With Network Firewall, you can filter traffic at the perimeter of your VPC. This includes filtering traffic going to and coming from an internet gateway, NAT gateway, or over VPN or Direct Connect. Network Firewall uses rules that are compatible with Suricata, a free, open source network analysis and threat detection engine. Network Firewall supports Suricata version 6.0.9. For information about Suricata, see the Suricata website.

You can use Network Firewall to monitor and protect your VPC traffic in a number of ways. The following are just a few examples:

- Allow domains or IP addresses for known Amazon Web Services service endpoints, such as Amazon S3, and block all other forms of traffic.

- Use custom lists of known bad domains to limit the types of domain names that your applications can access.

- Perform deep packet inspection on traffic entering or leaving your VPC.

- Use stateful protocol detection to filter protocols like HTTPS, regardless of the port used.

To enable Network Firewall for your VPCs, you perform steps in both Amazon VPC and in Network Firewall. For information about using Amazon VPC, see Amazon VPC User Guide.

To start using Network Firewall, do the following:

1. (Optional) If you don't already have a VPC that you want to protect, create it in Amazon VPC.

2. In Amazon VPC, in each Availability Zone where you want to have a firewall endpoint, create a subnet for the sole use of Network Firewall.

3. In Network Firewall, create stateless and stateful rule groups, to define the components of the network traffic filtering behavior that you want your firewall to have.

4. In Network Firewall, create a firewall policy that uses your rule groups and specifies additional default traffic filtering behavior.

5. In Network Firewall, create a firewall and specify your new firewall policy and VPC subnets. Network Firewall creates a firewall endpoint in each subnet that you specify, with the behavior that's defined in the firewall policy.

6. In Amazon VPC, use ingress routing enhancements to route traffic through the new firewall endpoints.
