• B) Triple data storage capacity
• C) Maintain data confidentiality
• D) Enhance system usability
Correct Option: C) Maintain data confidentiality
Rationale: The primary goals of information security generally focus on ensuring
confidentiality, integrity, and availability of data. Confidentiality involves protecting information
from unauthorized access.
2. What is the principle of least privilege?
• A) Users should have all privileges for usability
• B) Users are granted only the minimum level of access necessary
• C) Access is revoked after completion of tasks
• D) Privileges are determined by IT professionals only
Correct Option: B) Users are granted only the minimum level of access necessary
Rationale: The principle of least privilege is a security practice that restricts user access rights to
the bare minimum permissions they need to perform their job functions.
3. Which type of attack involves overwhelming a system with traffic to render it unusable?
• A) Phishing

4. What is the purpose of encryption in data security?
• A) To protect data confidentiality during transmission
• B) To improve data integrity
• C) To enhance data accessibility
• D) To expedite data processing speed
Correct Option: A) To protect data confidentiality during transmission
Rationale: Encryption serves to protect the confidentiality of data by transforming it into a
format that is unreadable without the corresponding decryption key.
5. Which standard focuses on managing and protecting sensitive data?
• A) HIPAA
• B) PCI DSS
• C) NIST SP 800-53
• D) ISO 27001

6. Which of the following is a common method for preventing unauthorized access to a
network?
• A) Firewalls
• B) Intrusion Detection Systems (IDS)
• C) Access Control Lists (ACLs)
• D) Network Protocols
Correct Option: C) Access Control Lists (ACLs)
Rationale: ACLs help define who can access certain resources in a network, enforcing security
by allowing only authorized users or systems.
7. What does HTTPS stand for?
• A) Hypertext Transfer Protocol Standard
• B) Hypertext Transfer Protocol Secure
• C) Hypertext Transfer Privacy Standard
• D) Hypertext Transfer Protocol Secure Layer
Correct Option: B) Hypertext Transfer Protocol Secure
