The Samm Self Assessment tool is an implementation of the OpenSAMM (www.opensamm.org) process wrapped together into a little Rails application. Its aim is to simplify the measurement of your organisation against OpenSAMM, and to assist in the construction of a roadmap, and subsequent tracking of progress down that roadmap.
Well, simply put, we think that OpenSAMM is a great process to help organisations measure the maturity of security within their software development lifecycle. Plus, we wanted something lightweight that could be stood up on a standalone desktop (with Rails), or even hosted on the Internet (Heroku/EC2/etc)
Without this measurement trying to improve the state of security within your software development lifecycle is going to be difficult. As they say: You can't manage what you can't measure.
(This is a fairly standard Rails app, so, these instructions are somewhat generic)
