Which of the following enables a user to use generic methods to access a database and to focus on the coding
rather than the syntax for a specific database API?
A.
Abstraction
B.
Database security
C.
Native auditing
D.
Authentication
Explanation:
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 thatit provides a
uniform interface for database access. Answer B is incorrect. 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 C 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 D is incorrect. Authentication is the process of verifying the identity of a
user or software connecting to a database. During the process of authentication, the user must submit
sufficient information validated either by the database itself, or by the operating system within which the
database is installed.
