New security paradigm for application security infrastructure

Abstract

The recent and upcoming computing environment is characterized by distribution, integration, collaboration and ubiquity. The existing security technology alone can not successfully provide necessary security services for this environment. Therefore, it is necessary that the provision of security services reflects the characteristics of such an environment. In this paper, we analyze security requirements for existing and upcoming applications and services. We then survey deployed security services and identify the required information security services to satisfy the result of the security requirement analysis. Hence we suggest UASI (Unified Application Security Infrastructure) as a new security paradigm. UASI is a framework, which describes how a single security infrastructure can provide all the necessary security services for the ubiquitous computing environment in a seamless manner. © Springer-Verlag Berlin Heidelberg 2003.
