A High Security System For Databases

Abstract - The intent of this paper is to give users of database softw be, a basic

understanding of the enhanced protective cover capabilities achieved through Hard track record

Shadowing over IP nedeucerks. The paper discusses the foundation and implementation of Hard

Disk Shadowing system over a package switched Internet Protocol(IP) network. The system

creates an accurate copy of scathing information at two drives simultaneously thus

providing identical failover storage devices on two servers.This leverages the existing IP

network infrastructure, hence minimizing deployment time and total cost of development.

I. INTRODUCTION

Timely access to accurate and up-to-date information is critical to the success of businesses and

institutions today. Applications such as business intelligence and e-commerce contract it, and

people attached with them expect it.With the volume of information nearly two-baser annually for

the larger organizations data storage, access and security are among the most demanding

challenges facing database management.

Database systems are today marked by a number of ingredients that can disrupt their normal

operations.The first divisor is information growth.The systems are handling considerable volumes of data,

and the volume is developing exponentially.As a result the system managers are swimming in disks

and tapes second factor is the increasing demand for access to applications. The work are now

required literally around the clock.



A third factor is that systems are changing all the time, with

new applications, major enhancements to .existing applications, and new technology. at long last the

database systems face continuo us intentional or unknowing security threats.

Each of these factors directly involve or impact movements of huge amounts of data, in

increments or all at once for one causa or another, from one location to another.Hard Disk

Shadowing can provide an ritzy solution for data protection, data replication and data

migration.
