A COMPARATIVE ANALYSIS OF SDLC MODEL WITH SECURE SOFTWARE DEVELOPMENT AND TESTING

Abstract The complicated and the emergent nature of the software systems make the environment of the data and its key components very unpredictable. The increasing demand of the software with cheaper cost, quick delivery and high quality than the former, has made the software development more complex and diverse. The software development models are useful for developing the software in a systematic manner and delivered within the constraint deadline. In this paper, starting from the initial liner model to the latest used model for software models is described. Comparative analysis of the models is done to show which is better against which parameter. The secure software development approach is also discussed which combines the different tools and approaches to make the software code less vulnerable to attackers. Latest used methodology agile methodology is described which make software development and user interaction more easy. After the development of software, testing is done with the various test cases to make it error free. Different types of the testing techniques such as Chi-squared test, Student's t-test, G-test, Unit testing and Wald test with the implementation formula are described.
