Security is of paramount importance in collaborative research projects, particularly those focusing on software development. The security of data processed by project-developed software relies on early consideration of security aspects during the software’s design and development process. Unfortunately, the unique characteristics of collaborative research projects often impede the seamless integration of security aspects, posing a risk of producing solutions with inadequate security properties. To tackle this challenge, this chapter introduces a generic method designed to seamlessly incorporate security aspects in development-oriented research projects. With an emphasis on broad applicability across diverse projects, the method maintains intentional generality. Through its application to the H2020 project mGov4EU, the chapter demonstrates the method’s practical effectiveness, highlighting its adaptability and utility in a concrete project scenario. This proposed method serves as a valuable tool for researchers and practitioners aiming to seamlessly integrate security within collaborative research projects, addressing potential vulnerabilities early and ensuring the development of more secure software solutions.
