One purpose of a database system is the easy sharing of data. But this ease of sharing can also jeopardize security. Discuss at least three forms of access control designed to reduce this risk
Many types of access control are possible. A user view is a subset of a database that limits a user's view or access to the database. The database authorization table contains rules that limit what a user can do, i.e., read, insert, modify, delete. A user-defined procedure adds additional queries to user access to prevent others from accessing in a specific user's place. To protect the data in a database, many systems use data encryption to make it unreadable by intruders. A newer technique uses biometric devices to authenticate users.
