Building Secure Software Using XP

Security is an important and challenging aspect that needs to be considered at an early stage during software development. Traditional software development methodologies do not deal with security issues and so there is no structured guidance for security design and development; security is usually an afterthought activity. This paper discusses the integration of XP with security activities based on the CLASP (Comprehensive Lightweight Application Security Process) methodology. This integration will help developers using XP develop secure software by applying security measures in all phases and activities, thereby minimizing the security vulnerabilities exploited by attackers.
