Section 1: Information Security Fundamentals & The CIA Triad (Questions 1–20)
1. What is the primary purpose of cybersecurity risk management?
A) To eliminate all cyber threats permanently
B) To identify, assess, and reduce risks to an acceptable level
C) To increase network bandwidth and system performance
D) To replace security teams with automated solutions
Correct Answer: B) To identify, assess, and reduce risks to an acceptable level
Rationale: Cybersecurity risk management focuses on identifying threats, assessing
vulnerabilities, and implementing controls to reduce organizational risk to an acceptable
level. It does not aim to eliminate all threats, as that is impossible.
2. Which security principle ensures that data is accessible only to authorized users?
A) Integrity
B) Confidentiality
,C) Availability
D) Accountability
Correct Answer: B) Confidentiality
Rationale: Confidentiality is the principle that protects sensitive information from
unauthorized disclosure. The CIA Triad consists of Confidentiality (who can see it), Integrity
(who can edit it), and Availability (keeping systems accessible).
3. An attacker intercepts and modifies a message during transmission. Which
principle of the CIA triad has been violated?
A) Confidentiality only
B) Availability only
C) Integrity
D) Authentication
Correct Answer: C) Integrity
Rationale: Integrity ensures that data is not altered without authorization. Modifying a
message during transmission directly violates the integrity principle.
4. Which of the following best describes the concept of "non-repudiation"?
A) Ensuring data is encrypted during transmission
B) Ensuring that a party cannot deny having performed a particular action
,C) Ensuring that data is backed up regularly
D) Ensuring that only authorized users can access data
Correct Answer: B) Ensuring that a party cannot deny having performed a particular
action
Rationale: Non-repudiation provides proof of the origin of data and ensures that a party
cannot deny having sent or received a message or performed an action.
5. The principle of "least privilege" means that:
A) Users should have the minimum permissions necessary to perform their job functions
B) All users should have the same level of access
C) Administrators should have unlimited access
D) Privileges should be granted based on seniority
Correct Answer: A) Users should have the minimum permissions necessary to
perform their job functions
Rationale: Least privilege limits user permissions to reduce security risks and unauthorized
access. Users receive only the access needed to complete their assigned tasks.
6. What is the primary goal of information security?
A) Increase system speed
B) Ensure confidentiality, integrity, and availability
, C) Reduce hardware cost
D) Improve UI design
Correct Answer: B) Ensure confidentiality, integrity, and availability
Rationale: The CIA triad (Confidentiality, Integrity, Availability) is the foundation of security.
All security controls ultimately support one or more of these three principles.
7. Which best defines confidentiality?
A) Data is always accessible
B) Data is not altered
C) Data is only accessible to authorized users
D) Data is backed up
Correct Answer: C) Data is only accessible to authorized users
Rationale: Confidentiality ensures only authorized access. It protects sensitive information
from unauthorized disclosure.
8. What does the principle of integrity ensure?
A) Systems stay online
B) Data remains accurate and unchanged
C) Users can access files remotely
D) Data is encrypted
