Security and Privacy Requirements Engineering

Security requirements engineering identifies security risks in software in the early stages of the development cycle. In this chapter, the authors present the SQUARE security requirements method. They integrate privacy requirements into SQUARE to identify privacy risks in addition to security risks. They then present a privacy elicitation technique and subsequently combine security risk assessment techniques with privacy risk assessment techniques. The authors discuss prototype tools that have been developed to support SQUARE for security and privacy as well as recent workshops that have focused on additional results in the security and privacy requirements area. Finally, the authors suggest future research and case studies needed to further contribute to early lifecycle activities that will address security and privacy-related issues.
