Software plays an important role in almost every aspect of our daily lives and dominates corporate, political and societal discourse. Over the last decade, we have seen a dramatic and broad technological and economic shift in which software systems become vital to large parts of the economy.

In this manifest we position the challenges for secure software in four clusters:

• the security of software,
• the agile development of secure software,
• the maintainability of secure software and evolution,
• the expertise to develop and maintain secure software.
