What is the main goal of a Denial-of-Service (DoS) attack?

The main goal of a Denial-of-Service (DoS) attack is to make a service unavailable to its intended users. This type of attack aims to overwhelm a target server, service, or network by flooding it with excessive requests, thereby disrupting the normal functioning of that system. As a result, legitimate users cannot access the service they need, leading to downtime and potential financial losses for businesses or individuals relying on that service.

The focus of a DoS attack is on disruption rather than improvement or enhancement of services. It does not aim to enhance network security or improve data transfer speeds; rather, it effectively results in the opposite. Similarly, facilitating communication between networks is not a goal of a DoS attack, as the intent is to hinder access and delay legitimate services. The nature of a DoS attack emphasizes its disruptive role in network operations, solidifying the understanding that option B accurately reflects its primary objective.
