A Survey on Data Security & Computer Networks

This research deals with data security in distributed and client/server computer systems, placing special emphasis on access security.

The paper presents the subject of data security & computer Networks in these systems by describing them, examining their vulnerable points and presenting adequate solutions. The paper includes a survey on the subject of authorization, authentication, encryption and access control, the main components in data security management of distributed systems. In addition to a survey and analysis of data security management aspects, a plan of an access security system based on client/server architecture is presented, which may be combined with applications requiring access security services. The model describes the access security server and the interface for access security which is combined with the application and constitutes the client portion.

Unlike research carried out to date which mainly integrates existing techniques and approaches (White 1999, Burleson 1998, Gayness 2000)? This research offers an innovative approach on the subject of data security management through the development of a unique access security Model. Furthermore, in view of the increasing importance and intensive use of data security management technology, and the special attention paid to the various aspects connected with data security management, this research is of special importance from the theoretical and applicative points of view.
