Abstract
It is critical to develop secure software with long-term performance and capability to withstand and forestall the growing competition in the software development industry. To enhance the potential of Confidentiality, Integrity, and Availability ( CIA), a mechanism is required to built in and secure the durability at the time of software development. Security of a software product is durable if the software works efficiently for user's satisfaction up to the expected duration. Despite the fact that focusing on security which is durable enough considerably reduces maintenance cost, the work done on addressing security as well as durability issues simultaneously during software development remains minimal. To achieve durable security, there is a need to fill the gap between security and durability through identifying and establishing a relationship between security and durability attributes. This article extends the concept of the life span of security services and assesses as well as prioritizes security durability attributes by taking a real-time case study. While building durable security, security experts often face complicated decision problems. Hence, multi-criteria decision-making techniques have been used to solve the issues of measuring conflicting tangible/ intangible criteria. In addition, the fuzzy simple average method is used for finding out the rating of security durability attributes. The work has been demonstrated by taking a case study. The results of the study would be useful for security developers to assure the importance of attributes for improving the duration of security. (c) 2019 The Authors. Published by Atlantis Press SARL.
