Fault Tree Analysis and Failure Mode Effects Analysis for Software Security Improvements in Mobile Banking Information Systems

Abstract

Due to rapid development of mobile device technologies, the mobile banking through Internet has become a major service of banking information systems as a security-critical information systems. Recently, lots of mobile banking information systems which handle personal and transaction information have been exposed to security threats in vulnerable security control and management processes, mainly software systems. Therefore, in this paper, we propose a process model for software security improvements in mobile banking information system by application of fault tree analysis(FTA) and failure modes and effects analysis(FMEA) on the most important activities such as 'user authentication' and 'access control' and 'virus detection and control' processes which security control and management of mobile banking information systems are very weak.

Defect Analysis Using Fault Tree Analysis and Failure Mode Effect Analysis in Rubber Roll Production

“…To evaluate these defective products, Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) methods can be employed (Ding et al, 2021). Fault Tree Analysis (FTA) is a top-down approach that begins with assuming errors or failures of an event and then delves deeper to reach the basic failures (Kim et al, 2015). Failure Mode and Effect Analysis (FMEA) is a method for identifying failures in a process or system (Wessiani & Yoshio, 2018;Rochmoeljati et al, 2022).…”
