IGI Global



In this chapter, we describe general issues in developing security requirements, methods that have been useful, and a method (SQUARE) that can be used for eliciting, analyzing, and documenting security requirements for software systems. SQUARE, which was developed by the CERT Program at Carnegie Mellon University's Soft-ware Engineering Institute, provides a systematic approach to security requirements engineering. SQUARE has been used on a number of client projects by Carnegie Mellon student teams, prototype tools have been developed, and research is ongoing to improve this promising method.
