Improving software security through an integrated approach

It has been recognized that the main source of problems with application software security is in most cases that the software is poorly designed and developed with respect to authentication and authorization. Aiming at preventing the security issues in the course of software design and development, this paper presents a framework for integrating a security policy specification with a system function integration. On the basis of the Role-Based Access Control (RBAC) model, this framework moves the responsibility of security through a central authorization management mechanism, Single Sign-On (SSO) access and integration management of security resources. The design can integrate the enterprise's multiple new, developing and existing application systems, and provide end users access these systems as a single system. An application instance of the framework is given in a large-sized enterprise information integrated system as well. The results show that the framework may provide enterprises with uniform and robust enforcement policies to improve the security of sensitive information systems.
