Secure Software Development Model: A Guide for Secure Software Life Cycle

EXtreme programming (XP) is a modern approach for iterative development of software in which one never wait for the complete requirements and start development. Security is usually unnoticed during early phases of software life cycle. In this paper, the main objective is to focus on security requirements at each phase of software life cycle. In this regard, XP is a key solution that provides one with a guide with the ease to recheck the security requirements, if they are unnoticed at any step of software life cycle. Based on XP technique, a new model has been designed that focuses on the concept of iterative development of secure software.
