Security in Distributed System: A Review Perspective

Abstract

Computer over the years has grown from single user to multi-user systems and then presently to distributed system, implying that computing resources can be distributed to different host and can be access by multiple users. This scenario is required for horizontally scaling of systems’ requirement against vertical scaling now known as distributed systems, which cannot be improved beyond certain threshold. Security in such a heterogeneous system becomes a paramount issue of concern. This paper looks at distributed system, while highlighting the security challenges inherent in such system and reviewing the various progress in providing solution to the security challenges.
