Review of security models applied to distributed data access

Abstract

In this paper, we explore the technologies behind the security models applied to distributed data access in a Grid environment. Our goal is to study a security model allowing data integrity, confidentiality, authentication and authorization for VO users. We split the process for data access in three levels: Grid authentication, Grid authorization, local enforcement. For each level, we introduce at least one possible technological solution. Finally, we show our vision of a SOA oriented security framework.
