While Software Development has not got a strict definition, due to the various processes implemented in literature and their customizable nature, it should, typically include a few required steps, also present in the most famous Waterfall Process describing the software development lifecycle.

It is now assured by the security expertise that having your applications secured during Testing and Release phases is a relevant misconception. Performing security audits on applications prior to deploying them on production environments usually results in having developers facing many security issues and articulated flaws, solving them in short terms in order to respect deadlines agreements. In worse cases, the issues are caused by architectural problems within the code itself, dramatically increasing production costs and causing deployment delays because of the needed re-coding.

Based on these assertions, NTT Security has acquired knowledge and experienced best practice in what is now commonly defined as the "Secure Software Development Lifecycle".
