Selection of secured software development process model

In today's terms with developing tecnology, software security and secured software process selection criteria are becoming increasingly important. Security is an important property of any software for many applications are outsourced where the application deveopment lacks strong integration of software security. These six software process selection criterias are considered by various factors. After working on these software process selection criterias, the importance of selecting a model is explained for protecting the companies which develops software by system attacks.A set with thirty-five criteria and six functional point values was created. The selected six software process selection models were evaluated with this set. A most wanted secured software process selection model was created with this criteria set and the other six software process selection models were compared with this wanted secured model. As a result the most secured software process selection model and the least secured software pocess selection model were determined. As a sample the same set was applied to three living software projects to find which software process selection model is used.As a result of the study, the applicability of many major projects , the user is able to test in every cycle of processing software and a project manager can observe at every stage of the project and at every stage of the test , the Spriral Model was determined as the most reliable and the most preferred model as a model of the software development process. In the same way Prototypes are slow and cumber and is also the possibility of customers' perception of the prototype model was developed as a prototype for at least the actual program was determined as the most preferred software development process model identified as unsafe.
