Mark works as the Database Administrator for DataWorld Inc. The company has a SQL server 2008
database. Mark wants to protect the database from unintended activities made by authorized
individuals or processes such as authenticated misuse, malicious attacks, or inadvertent mistakes.
Which of the following should he use to accomplish the task?

A.
Native auditing

B.
Abstraction

C.
Referential integrity

D.
Database security

Explanation:
Database security refers to the system, processes, and procedures that protect a database from
unintended activities, such as authenticated
misuse, malicious attacks, or inadvertent mistakes made by authorized individuals or processes.
Database security can begin with the process
of creating and publishing appropriate security standards for the database environment. These
standards may include specific controls for the
various relevant database platforms.
Answer B is incorrect. Abstraction is a method of coding that enables a user to focus on the coding
rather than the syntax for a specific

database API. A user can use generic methods to access a database. In order to perform database
abstraction, a user requires additional
code or libraries. The benefit of database abstraction is that it provides a uniform interface for
database access.
Answer A is incorrect. Native auditing is the process of extracting trails on a regular basis so that
they can be transferred to a
designated security system where the database administrators do not have access. This ensures a
certain level of segregation of duties and
provides evidence that the native audit trails were not modified by authenticated administrators.
Answer C is incorrect. Referential integrity is a feature or property that prevents users or
applications from entering inconsistent data which, when satisfied, requires every value of one
column of a table to exist as a value of another column in a different or the same table.
