Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence.

To learn more about Tsunami, visit our documentation.

Tsunami relies heavily on its plugin system to provide basic scanning capabilities. All publicly available Tsunami plugins are hosted in a separate google/tsunami-security-scanner-plugins repository.

Current Status

• Currently Tsunami is in 'pre-alpha' release for developer preview.
• Tsunami project is currently under active development. Do expect major API changes in the future.

Quick Start

For simplicity, we provide a Dockerfile that should cover most of the use cases.

You need to check-out the plugins and the callback server of Tsunami in the root directory, next to the Dockerfile. We do not perform this step in the Dockerfile so that you can modify plugins or the callback server configuration easily during the development phase.

$ git clone https://github.com/google/tsunami-security-scanner-plugins
$ git clone https://github.com/google/tsunami-security-scanner-callback-server
$ docker build -t tsunami:latest .

You will then be able to use the docker image, for example:

$ docker run -it --rm tsunami:latest bash
(docker) # tsunami --ip-v4-target=127.0.0.1 ## starts tsunami
(docker) # tsunami-tcs ## runs the callback server
(docker) # tsunami-linter ## linter for the templated language

Whenever you make a change to a plugin, you need to reiterate the build phase. While in the middle of development, we recommend commenting out the Stage 2 of the Dockerfile so that you can directly build changed plugins directly in the Docker.

Configuration files can be found in /usr/tsunami/tsunami.yaml for the scanner and /usr/tsunami/tcs_config.yaml for the callback server.

Also note that to use the callback server, you might have to setup port forward with your docker when starting it. We encourage you to refer to the -p option of Docker.
