Crate aws_sdk_networkfirewall

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..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.

Getting Started

Examples are available for many services and operations, check out the examples folder in GitHub.

The SDK provides one crate per AWS service. You must add Tokio as a dependency within your Rust project to execute asynchronous code. To add aws-sdk-networkfirewall to your project, add the following to your Cargo.toml file:

[dependencies]
aws-config = { version = "1.1.7", features = ["behavior-version-latest"] }
aws-sdk-networkfirewall = "1.24.0"
tokio = { version = "1", features = ["full"] }

Then in code, a client can be created with the following:

use aws_sdk_networkfirewall as networkfirewall;

#[::tokio::main]
async fn main() -> Result<(), networkfirewall::Error> {
    let config = aws_config::load_from_env().await;
    let client = aws_sdk_networkfirewall::Client::new(&config);

    // ... make some calls with the client

    Ok(())
}

See the client documentation for information on what calls can be made, and the inputs and outputs for each of those calls.

Using the SDK

Until the SDK is released, we will be adding information about using the SDK to the Developer Guide. Feel free to suggest additional sections for the guide by opening an issue and describing what you are trying to do.

Crate Organization

The entry point for most customers will be Client, which exposes one method for each API offered by AWS Network Firewall. The return value of each of these methods is a “fluent builder”, where the different inputs for that API are added by builder-style function call chaining, followed by calling send() to get a Future that will result in either a successful output or a SdkError.

Some of these API inputs may be structs or enums to provide more complex structured information. These structs and enums live in types. There are some simpler types for representing data such as date times or binary blobs that live in primitives.

All types required to configure a client via the Config struct live in config.

The operation module has a submodule for every API, and in each submodule is the input, output, and error type for that API, as well as builders to construct each of those.

There is a top-level Error type that encompasses all the errors that the client can return. Any other error type can be converted to this Error type via the From trait.

The other modules within this crate are not required for normal usage.
