Modern society is deeply and irreversibly dependent on software systems of remarkable scope and complexity in areas that are essential for preserving our way of life. The security and correct functioning of these systems are vital. Recognizing these realities, the U. S. Department of Homeland Security (DHS) National Cyber Security Division (NCSD) enlisted the resources of the Software Engineering Institute at Carnegie Mellon University to develop a curriculum for a Master of Software Assurance degree program and define transition strategies for implementation. In this article, we present an overview of the Master of Software Assurance curriculum project, including its history, student prerequisites and outcomes, a core body of knowledge, and a curriculum architecture from which to create such a degree program. We also provide suggestions for implementing a Master of Software Assurance program.
