Sample questions

1. Which of the following is NOT a fundamental principle of cybersecurity?

   1. Confidentiality
   2. Integrity
   3. Availability
   4. Anonymity
   Show answer

   Answer: D. Anonymity

   While anonymity can be a desirable feature in some contexts, it's not a core principle of cybersecurity. Confidentiality, integrity, and availability (CIA triad) are the fundamental pillars.

2. Explain the concept of 'least privilege' in cybersecurity.

   1. Giving users only the necessary access rights.
   2. Granting maximum privileges to all users.
   3. Restricting access to only system administrators.
   4. Allowing users to access all files and folders.
   Show answer

   Answer: A. Giving users only the necessary access rights.

   The principle of least privilege dictates that users and processes should only be granted the minimum access rights required to perform their tasks. This limits the potential damage from compromised accounts or malware.

3. How does multi-factor authentication (MFA) enhance security?

   1. By relying solely on passwords.
   2. By requiring multiple forms of verification.
   3. By simplifying login procedures.
   4. By using only biometric data.
   Show answer

   Answer: B. By requiring multiple forms of verification.

   MFA adds layers of security by demanding more than one verification method, such as a password and a code from a mobile app, making unauthorized access significantly harder.

4. What is a vulnerability in the context of cybersecurity?

   1. A security measure implemented to protect data.
   2. A weakness that can be exploited by attackers.
   3. A type of malware that infects systems.
   4. A strong password that cannot be easily guessed.
   Show answer

   Answer: B. A weakness that can be exploited by attackers.

   A vulnerability is a flaw or weakness in a system's design, implementation, operation, or internal controls that could be exploited by a threat actor to gain unauthorized access or cause damage.

5. How does a denial-of-service (DoS) attack work, and what is its goal?

   1. Stealing sensitive data.
   2. Installing malware on a system.
   3. Flooding a system with traffic to make it unavailable.
   4. Disrupting network communication through encryption.
   Show answer

   Answer: C. Flooding a system with traffic to make it unavailable.

   DoS attacks overwhelm a target system (server, network, etc.) with a massive amount of traffic, making it unresponsive to legitimate requests. The goal is to disrupt service availability, not necessarily steal data.
