SSH Certification Authority as Plugin for WaTTS

Description

The INDIGO DataCloud [0] implements authentication and authorization services for the Cloud as well as orchestrating services to spin up a huge number of virtual servers on demand. Some users might need to get access to these VMs, maybe even for a limited of time. Usually remote access to VMs is done through the secure shell (ssh [1]). Managing all the accesses in a very dynamic environment is hard to manage.

The goal of this project is to develop a plugin for WaTTS [2], the INDIGO Token Translation Service, that functions as a SSH-CA, so that only one public key needs to be deployed on all VMs.

Tasks

• understanding ssh-ca
• getting familiar with WaTTS and how to implement a plugin
• implement the plugin

Requirements

• good knowledge of Linux
• working with the command line
• programming experience e.g. python or go
