An Integrative Method of FTA and Software FMEA for Security Analysis of a Smartphone

Abstract

Recently, software security of the smartphone is an important issue in the field of information science and technology, due to fast propagation of smart technology in our life. Smartphone, as one of the security critical systems which are utilizing for terminal systems of the smart banking, ubiquitous home management, airline passengers screening, map directions, mobile government, disaster detections, are related to the risks of accidents, losses, unavailability, misuses and so on. The security issues mentioned above, and meanwhile software hazard analysis is the key-approaching concepts for these failures. Fortunately, we propose an integrating efficient architecture for software security analysis of the smartphone by using fault tree analysis (FTA) and software failure mode and effect analysis (SFMEA) to gain a convergence safety and reliability technique on hand handle device. FTA system is interpreted by involving cut-set analysis. Possibly, there have been a lot of tool and methodology regarding to the software security analysis system methods and concepts. However, for these cases within this research, we consider step taken by business process management to dissect all the fault and failure within an implementation of integrative software of failure mode effect analysis and fault three analysis, this method is the new technique for analyzing and evaluating failure paths in a system, either in a lateral of hardware and or software. Since the inception of FTA, fault tree theory, methods and computer codes have improved significantly. The key-concept for this method is to integrate a complex fault of securities inside smartphone in to a fault three cut-sets. To perform a failure mode effect analysis more comprehensive, not only for security reason but also failure problems of this device is a key-method for solution. Thus, in this thesis, we propose an integrative method of FTA and software FMEA for security system of the smartphone by deploying an integrated method is to be a specific software security analysis, this thesis discusses the design and operation feature of FTA and software FMEA, along with its capabilities and benefits.
