ssh_scan

A SSH configuration and policy scanner

⚠️ Deprecation Notice ⚠️

Mozilla is no longer maintaining the SSH Scan project.

Please fork it to continue development.

Key Benefits

Minimal Dependencies - Uses native Ruby and BinData to do its work, no heavy dependencies.
Not Just a Script - Implementation is portable for use in another project or for automation of tasks.
Simple - Just point ssh_scan at an SSH service and get a JSON report of what it supports and its policy status.
Configurable - Make your own custom policies that fit your unique policy requirements.

Setup

To install and run as a gem, type:

gem install ssh_scan
ssh_scan

To run from a docker container, type:

docker pull mozilla/ssh_scan
docker run -it mozilla/ssh_scan -t sshscan.rubidus.com

To install and run from source, type:

# clone repo
git clone https://github.com/mozilla/ssh_scan.git
cd ssh_scan

gem install bundler
bundle install

./bin/ssh_scan
