Now in each of these cases, what we want to have is a software development lifecycle that brings together the components that sees to these four elements being emphasized. Secure by design. Secure by default, and then to account for all of the different things that can happen to throw a monkey wrench into this, to make sure that it is secure in deployment, and then secure in its communications, to be sure that we are treating all of the information in all of its states with the proper care and security as it needs. And the components that we bring together, if we're using this Microsoft SDL model, which blends a lot of the best features from all of the others, and can give these to all of the others. We look at all the different ways that we can integrate the best of development, the best of requirements management, project management, and security in the design and implementation, the verification, the release and the response processes that we find through the software development lifecycle.
