What does a DoS attack primarily aim to achieve?

A DoS (Denial of Service) attack primarily aims to make a server unusable by overwhelming it with a flood of malicious traffic or overwhelming requests that it cannot handle. This results in legitimate users being unable to access the targeted server or service, leading to downtime and potential loss of revenue for the affected organization. The primary goal is disruption rather than theft or unauthorized access.

In contrast, options focused on stealing sensitive data, gaining unauthorized access, or installing malware point to different types of security threats, such as data breaches or malware infections, which typically aim to exploit vulnerabilities for malicious purposes. DoS attacks specifically target availability, making them distinct in their objectives and methods.
