Question 3
  1. We are asked:
    “Which type of attack overloads a network with excessive requests, preventing normal operations?”
  2. A network is overloaded when it receives too many requests, which prevents it from responding to legitimate traffic. This type of attack is known as a denial-of-service (DoS) attack or, when distributed across multiple sources, as a distributed denial-of-service (DDoS) attack.
  3. Among the given options:
    • (a) Man-in-the-middle attack: Involves intercepting communications between two parties.
    • (b) SQL injection: Involves inserting malicious SQL queries into an application to manipulate a database.
    • (d) Ransomware: Involves encrypting a victim’s data and demanding a ransom.
  4. None of these options exactly match the description of overloading a network with excessive requests. The correct answer should be a denial-of-service attack, which is missing from the provided choices.
  5. Thus, the correct answer is the denial-of-service (DoS) attack, which corresponds to choice © (assuming it was meant to be listed, but it is absent).

Question 4
  1. We are asked:
    “What are the three elements of the CIA triad in cybersecurity?”
  2. The CIA triad stands for the fundamental security principles:
    • Confidentiality: Ensuring that information is not disclosed to unauthorized individuals.
    • Integrity: Assuring the accuracy and completeness of data.
    • Availability: Guaranteeing that information and resources are accessible to authorized users when needed.
  3. Comparing the choices:
    • (a) Confidentiality, Integrity, Availability
    • (b) Control, Implementation, Authentication
    • © Cryptography, Identification, Authorization
    • (d) Compliance, Investigation, Action
  4. The correct answer is clearly (a) Confidentiality, Integrity, Availability.

Final Answers:
  1. The correct answer is a denial-of-service (DoS) attack (which would typically be listed as option ©, though it is not shown here).
  2. The correct answer is (a) Confidentiality, Integrity, Availability.

Bonus Knowledge

Did you know that the type of attack that overwhelms a network with an avalanche of requests is called a DDoS (Distributed Denial of Service) attack? This malicious act can knock websites offline and disrupt services, causing havoc for businesses and users alike! Cybercriminals usually harness a botnet of compromised devices to launch these assaults, turning innocent gadgets into attack machines without their owners’ knowledge.
As for the CIA triad, it’s the cornerstone of cybersecurity! It stands for Confidentiality, Integrity, and Availability. This framework helps organizations safeguard data by ensuring it’s only accessible to authorized users (Confidentiality), that the data remains accurate and protected from unauthorized changes (Integrity), and that the data is readily available to authorized users when needed (Availability). Keeping these principles in balance is essential for a robust security strategy!
