The goal of a Denial of Service (DOS) attack is to make a network resource unavailable to users. In such an attack, the perpetrator aims to overwhelm a system, server, or network with a flood of malicious traffic, which can lead to legitimate users being unable to access the affected resources. This can impact businesses significantly, causing downtime and potential loss of revenue and reputation. By targeting the availability of services, the attacker disrupts normal operations and can render essential functions inoperative.

The other options do not accurately represent the intent of a DOS attack. Improving network performance, creating backup copies of data, or enhancing security measures are not associated with the disruptive nature of DOS attacks. Instead, these actions focus on maintaining or enhancing the integrity and accessibility of a network, which is contrary to the objectives of a DOS attack.
