Mapping of McGraw Cycle to RUP Methodology for Secure Software Developing
Designing a secure software is one of the major phases in developing a robust software. The McGraw life cycle, as one of the well-known software security development approaches, implements different touch points as a collection of software security practices. Each touch point includes explicit instructions for applying security in terms of design, coding, measurement, and maintenance of software. Developers are able to provide secure and robust software by applying such touch points. In this paper, we introduce a secure and robust approach to map McGraw cycle to RUP methodology, named RUPST. The traditional form of RUP methodology is revised based on the proposed activities for software security. RUPST adds activities like security requirements analysis, abuse case diagrams, risk-based security testes, code review, penetration testing, and security operations to the RUP disciplines. In this regard, based on RUP disciplines, new touch points of software security are presented as a table. Also, RUPST adds new roles such as security architect and requirement analyzer, security requirement designer, code reviewer and penetration tester which are presented in the form of a table along with responsibilities of each role. This approach introduces new RUP artifacts for disciplines and defines new roles in the process of secure software design. The offered artifacts by RUPST include security requirement management plan, security risk analysis model, secure software architecture document, UMLSec model, secure software deployment model, code review report, security test plan, security testes procedures, security test model, security test data, penetration report, security risks management document, secure installation and configuration document and security audit report. We evaluate the performance of the RUPST in real software design process in comparison to other secure software development approaches for different security aspects. The results demonstrate the efficiency of the proposed methodology in developing of a secure and robust software.
