Deployment options

FAST is a two-component solution, comprising the FAST node and the Wallarm cloud.

To conduct application testing, HTTP or HTTPS requests are proxied through the FAST node first. FAST creates a new request set based on the original queries according to policy obtained from the cloud. The newly created requests form a security test set that is executed in order to test the application for vulnerabilities.

A process of testing with FAST

Baseline requests (the original requests to the applications) can be obtained from different sources. For example, baseline requests can be written by an application tester or generated by an existing testing automation tool. FAST does not require all of the baseline requests to be malicious ones: a security test set could be generated based on legitimate requests as well. The FAST node is used for security test set creation and execution purposes.

How FAST works

Available deployment options

You have a choice of three FAST node deployment options. The node installation could be located at

  1. The host that serves as a baseline request source (a tester’s laptop, for example)
  2. The host where the target application resides
  3. The dedicated host

FAST deployment options

Main deployment considerations

FAST node is shipped as a Docker container and could be run on every platform that supports Docker (this includes Linux, Windows and macOS).

An account in the Wallarm cloud is a mandatory requirement for FAST deployment. The cloud is responsible for providing a user interface for FAST configuration. The testing results are also gathered by the cloud.

After completing the FAST node deployment you should ensure that

  1. The node has access to the target application
  2. The node has access to the Wallarm cloud
  3. All the baseline HTTP or HTTPS requests will be proxied through the node

SSL certificate installation

In the case of using HTTPS to interact with the target application, the request source might not trust the self-signed SSL certificate obtained from the FAST node installation. For example, if you use the Mozilla Firefox browser as the requests source, you may encounter a similar message (it may differ for other browsers or request sources):

“Insecure connection” message

To resolve the certificate issue, you have two options:

  1. To install the self-signed SSL certificate from FAST node as a trusted certificate to the request source
  2. To install the existing trusted SSL certificate to your FAST node

FAST deployment specifics in the Quick Start guide

This guide aims to demonstrate the FAST operation by exploiting the deployment option where the node is installed locally with the request source.

The installation that is used in this guide has the following specifics:

  • The Mozilla Firefox browser serves as the baseline request source
  • One HTTPS baseline request is constructed
  • A self-signed SSL certificate from the FAST node is installed into the browser
  • Google Gruyere serves as the target application
  • The target application is tested against XSS vulnerabilities
  • The policy is created with the web interface of Wallarm cloud
  • The testing process is started with the web interface of Wallarm cloud

Quick Start guide deployment scheme

Google Gruyere

Google Gruyere is a purpose-built application for security testing. It contains a lot of intentionally integrated vulnerabilities. Therefore, every application instance runs in an isolated sandbox for security reasons. To begin working with the application, you should navigate to https://google-gruyere.appspot.com and run a sandbox with the separated instance of Gruyere application.
