Denial of Service Attacks are categorized under which broader category?

• A. Integrity Attacks
• B. Access Control Attacks
• C. Confidentiality Attacks
• D. Availability Attacks

Answer: (D)

Denial of Service attacks target the availability of a service, aiming to make networks, systems, or applications unusable for legitimate users. This directly relates to the Availability aspect of the CIA triad, which covers ensuring that authorized users can access data and services when needed. The intent of a DoS attack isn’t primarily to steal data (confidentiality), alter data (integrity), or bypass authentication/authorization controls (access control). It’s about keeping resources busy or overwhelmed so legitimate customers can’t reach the service, which is why the broad category is Availability Attacks.
