A Mathematical Model for SelectingOptimal SecuritySolutions inBusiness Processes

Abstract

The business process plays a key role in gaining competitive advantage for the organization. The non-stop operation of daily operations processes is considered as one of the important indicators of the quality of business processes. As business processes face a variety of threats, organizations have to pay enough attention to the security requirements of business processes. However, increasing the level of security in organizations reduces the costs of security breaches, but imposes on the organization direct and indirect costs of deploying security requirements. In this paper, a mathematical model is proposed to determine the optimal decision to select security mechanisms among the options available for each activity in the business process with the aim of maximizing the level of security and minimizing the costs of deploying security mechanisms. The proposed model was solved by considering the purchasing process in one of the online stores using the genetic algorithm. The proposed model was validated by comparing the answer of the mathematical model with the answer of the experts.
