- Security in general and database protection from unauthorized access in particular, are crucial for organizations. It has long been accepted that security requirements should be considered from the early stages of the development process. However, such requirements tend to be neglected or dealt-with only at the end of the development process. The Security Modeling Tool presented in this paper aims at guiding and enforcing developers, in particular database designers, to deal with database authorization requirements from the early stages of the development process. In this paper we demonstrate how the Security Modeling Tool assists the various stakeholders in designing secure database code and describe the tool architecture.
