A STUDY ON DATABASE SECURITY THREATS AND MECHANISMS

Abstract

The heart of secure systems lies in protecting data and most of the users usually rely on database management
systems or DBMS for managing this protection. The security of databases is more of a recent development as compared to
the programming and operating systems. Databases play an important role in many business, government and private
organizations. They are used for making the retrieval and maintenance of data quite easy and become efficient when the data
is stored in databases. The basic requirements for any database systems aren’t like other computing systems. The major
systems faced for databases include access control, authentication process of users and their benefits. Several security
mechanisms are being used for storing and securing the large volumes of data. The reason why databases are attacked so
often is due to the fact that the databases contain large volume of data stored in them. This paper discusses the various
security mechanisms used. Further this paper also discusses about some of the major threats and challenges in database
security.
