What characteristic describes a DoS attack?

Explanation: A Denial of Service (DoS) attack is a malicious attempt to prevent legitimate users from accessing network services or resources by intentionally consuming system capacity. According to the sources, the primary characteristic of this attack type is that it is designed to slow or crash the applications and processes running on a network device. While other security threats such as identity theft or spyware focus on stealing data or monitoring user activity, DoS attacks prioritize the disruption of service availability, often leading to significant operational downtime and financial loss for an organization.
