Measuring Security of Web Services in Requirement Engineering PhaseInternational Journal of Cyber-Security and Digital Forensics (IJCSDF) (2012)
AbstractAddressing security in early stages of web service development has always been a major engineering trend. However, to assure security of web services it is required to perform security evaluation in a rigorous and tangible manner. The results of such an evaluation if performed in early stages of the development process can be used to improve the quality of the target web service. On the other hand, it is impossible to remove all of the security faults during the security analysis of web services. As a result, absolute security is never possible to achieve and a security failure may occur during the execution of web service. To avoid security failures, a measurable level of fault tolerance is required to be achieved through partial satisfaction of security goals. Thus any proposed measurement technique must care for this partiality. Even though there are some approaches toward assessing the security of web services but still there is no precise model for evaluation of security goal satisfaction specifically during the requirement engineering phase. This paper introduces a Security Measurement Model (SMM) for evaluating the Degree of Security (DS) in security requirements of web services by taking into consideration partial satisfaction of security goals. The proposed model evaluates overall security of the target service through measuring the security in Security Requirement Model (SRM) of the service. The proposed SMM also takes into account cost, technical ability, impact and flexibility as the key features of security evaluation.
