XACML (extensible Access Control Markup Language) is an open standard language based on XML. It’s the de facto language designed to describe the security policy and the access permission of network service, digital rights management and enterprise security applications information. RBAC profile of XACML is used to express policies that use role based access control. However, RBAC access decision is not influenced by the spatiotemporal context of both the subjects and the objects in the system. In this paper, we extend this profile with spatiotemporal RBAC profile. It incorporates different constraints dependent on spatiotemporal conditions. The spatiotemporal conditions allow to enhance the access control of XACML by specifying a wide variety of spatiotemporal access control policies. The extension facilitates the administration by providing a convenient and efficient way of managing access control policies.

Requirements Engineering (RE) is a very critical phase in System Development Life Cycle (SDLC). There are several attempts to enhance the quality and performance of this phase and therefore enhancing the industry of producing software systems. Caring about the quality of software systems doesn’t mean just testing the product before deployment. Improving quality of software systems must begin from eliciting requirements from stakeholders to ensure that the right product is being developed. Any error in this phase will enforce to repeat the work which will cost a lot. Deficient requirements are the cause of many software systems failures. So many researches try to enhance the quality of RE and achieve stakeholders’ satisfaction. In this paper, we review and provide some of these attempts. This survey will support the future research and development work as well as to raise the awareness for the presented approaches.
