Security issues for the software evolution model

摘要

This thesis examines the security requirements of the software evolution model and identifies possible security mechanisms called "control classes" that are applicable to the model. Then, based on combinations of "control lasses," proposes a suitable security level for each of the model's databases. Furthermore this thesis deals with the possibility of using Pretty Good Privacy as a method for protection of software data stored in databases. The software evolution model captures all the necessary changes in requirements early during the development process in order to help in minimization of project cancellation, delivery delays and extra costs for fixing errors. The protection of software data against unauthorized accesses and modifications is a primary consideration for the software evolution process. In this way, we can develop a secure environment on which the software evolution can rely for accomplishing its goal
