Abstract

Software Reliability is the probability of failure-free software operation for a specified period of time in a specified environment. Cyber threats on software security have been prevailing and have increased exponentially, posing a major challenge on software reliability in the cyber physical systems (CPS) environment. Applying patches after the software has been developed is outdated and a major security flaw. However, this has posed a major software reliability challenge as threat actors are exploiting unpatched and insecure software configuration vulnerabilities that are not identified at the design phase. This paper aims to investigate the SDLC approach to software reliability and quality assurance challenges in CPS security. To demonstrate the applicability of our work, we review existing security requirements engineering concepts and methodologies such as TROPOS, I*, KAOS, Tropos and Secure Tropos to determine their relevance in software security. We consider how the methodologies and function points are used to implement constraints to improve software reliability. Finally, the function points concepts are implemented into the CPS security components. The results show that software security threats in CPS can be addressed by integrating the SRE approach and function point analysis in the development to improve software reliability.
