A Denial of Service (DoS) attack primarily focuses on overwhelming a network's resources by generating excessive traffic. This surge in traffic significantly impacts the network's bandwidth, which is the capacity of the network to transmit data. When a DoS attack floods a network with an overwhelming amount of requests, it consumes available bandwidth, leading to slowdowns or complete disruptions in legitimate traffic. This results in a situation where users cannot access services due to the congestion caused by the attack.

While end users, applications, and servers may also experience degradation in performance as a result of the bandwidth issues caused by the attack, it is the bandwidth itself that is most directly affected by the immense volume of malicious traffic associated with DoS attacks. Therefore, understanding the impact of a DoS attack at the bandwidth level is crucial for implementing effective network security measures and ensuring the stability and availability of services.
