Multiple choice.

Section 1: Information Security Fundamentals (Questions 1–
10)
1. Which of the following is NOT a component of the classic
“CIA triad” in information security?
A) Confidentiality
B) Integrity
C) Availability
D) Authenticity

, Page 2 of 51


Answer: D. Authenticity
Explanation: The CIA triad consists of Confidentiality,
Integrity, and Availability. Authenticity is related but is often
considered a separate objective or part of non-repudiation.
2. A hacker steals a database of customer credit card
numbers. Which security principle has been violated?
A) Integrity
B) Confidentiality
C) Availability
D) Authorization
Answer: B. Confidentiality
Explanation: Confidentiality ensures that sensitive
information is not disclosed to unauthorized individuals.
Theft of credit card numbers is a breach of confidentiality.
3. A user accidentally deletes a critical file. Which security
principle is directly impacted?
A) Confidentiality
B) Integrity
C) Availability
D) Non-repudiation
Answer: C. Availability
Explanation: Availability means that authorized users can
access data when needed. Deletion of a critical file makes it
unavailable, although integrity may also be affected if
backups are corrupted.

4. The “separation of duties” control is designed to:
A) Increase the speed of business processes
B) Prevent a single individual from having too much control or
being able to commit fraud without collusion
C) Reduce the number of employees needed for a task
D) Ensure all employees have equal access to data
Answer: B. Prevent a single individual from having too much
control or being able to commit fraud without collusion
Explanation: Separation of duties divides critical tasks
among multiple people, so no one person can subvert a
process without detection. It is a key internal control in
financial and security systems.
5. An organization implements mandatory vacation policies
for employees in sensitive roles. This is primarily intended
to:
A) Give employees rest and increase morale
B) Detect fraud or errors that require the employee’s presence to
conceal
C) Reduce payroll costs
D) Comply with labor laws
Answer: B. Detect fraud or errors that require the employee’s
presence to conceal
Explanation: Mandatory vacations force employees to be
away from work, making it harder to cover up ongoing fraud
or irregularities. This is a detective control often used in
financial and security environments.

6. Which term describes the process of verifying that a user’s
claimed identity is valid?
A) Authorization
B) Auditing
C) Authentication
D) Accounting
Answer: C. Authentication
Explanation: Authentication proves identity (e.g., via
password, biometric). Authorization determines what an
authenticated user can do. Accounting (auditing) records
their actions.
7. The “defense in depth” strategy means:
A) Relying on a single, very strong firewall
B) Layering multiple security controls (administrative, technical,
physical) so that if one fails, others still protect the asset
C) Only protecting the perimeter of the network
D) Eliminating all security controls to reduce complexity
Answer: B. Layering multiple security controls
(administrative, technical, physical) so that if one fails,
others still protect the asset
Explanation: Defense in depth uses overlapping protections
at different levels (network, host, application, data) to
provide redundancy in security.
8. Which of the following is an example of an “administrative
control”?
