What outcome does a Denial of Service (DoS) attack aim to achieve?

A Denial of Service (DoS) attack specifically aims to make a resource unreachable to its intended users. In such an attack, the perpetrator attempts to overwhelm a service, server, or network by flooding it with excessive requests or exploiting vulnerabilities, leading to the degradation or complete failure of the service. The ultimate goal is to disrupt legitimate users' access to that resource, rendering it ineffective for its intended purpose.

This outcome aligns with the fundamental nature of DoS attacks, which is to hinder functionality and availability, rather than enhancing performance, improving security, or gathering data, which are not associated goals of a DoS attack. Therefore, making a resource unreachable is a direct reflection of what a DoS attack strives to accomplish.
