For whichever software development methodology your organisation implements, you’ll find a common structure between the various models. These five phases of a software development life cycle can be identified in each methodology:
Planning – Start your secure software development by mapping out a timeline, requirements, and any preliminary details necessary.
Analysis – The organisation defines objectives, project goals, and the functions and operations of the application.
Design – Detailed screen layouts, business rules, process diagrams, pseudocode, and other documentation is laid out. Development begins, and secure code is written.
Implementation – Testing and integration bring all the pieces together in an environment that checks for errors, bugs, vulnerabilities, gaps, and interoperability.
Maintenance – Once your software is developed, maintaining updates, performance evaluations, and making any changes to the initial software are key maintenance procedures.
