Question 275

Which of the following is a mechanism that helps in ensuring that only the intended and authorized recipients
are able to read data?

A.Integrity
B.Data availability
C.Confidentiality
D.Authentication

Correct Answer: C

Confidentiality is a mechanism that ensures that only the intended and authorized recipients are able to read
data. The data is so encrypted that even if an unauthorized user gets access to it, he will not get any meaning
out of it.
Answer option A is incorrect. In information security, integrity means that data cannot be modified without
authorization. This is not the same thing as referential integrity in databases. Integrity is violated when an
employee accidentally or with malicious intent deletes important data files, when a computer virus infects a
computer, when an employee is able to modify his own salary in a payroll database, when an unauthorized
user vandalizes a web site, when someone is able to cast a very large number of votes in an online poll, and so
on. There are many ways in which integrity could be violated without malicious intent. In the simplest case, a
user on a system could mistype someone's address. On a larger scale, if an automated process is not written
and tested correctly, bulk updates to a database could alter data in an incorrect way, leaving the integrity of the
data compromised. Information security professionals are tasked with finding ways to implement controls that
prevent errors of integrity.
Answer option B is incorrect. Data availability is one of the security principles that ensures that the data and
communication services will be available for use when needed (expected). It is a method of describing
products and services availability by which it is ensured that data continues to be available at a required level of
performance in situations ranging from normal to disastrous. Data availability is achieved through redundancy,
which depends upon where the data is stored and how it can be reached.
Answer option D is incorrect. Authentication is the act of establishing or confirming something (or someone) as
authentic, i.e., the claims made by or about the subject are true ("authentification" is a variant of this word).
