摘要：Secure software is the demand of time in this connected world. Security needs to be given high priority in software development life cycle. Considering security as a non-functional requirement in software and giving a side thought to it after development of software only results a software with vulnerabilities. Software engineering is still lagging in secure software development processes. Due to it’s critically, security should be integrated in software life cycle process from the very beginning of development of software. Current research implements the secure development phases in spiral model and proposes a new security aware spiral.
