What is a DDoS attack primarily designed to do?

A DDoS (Distributed Denial of Service) attack is primarily designed to disrupt normal network traffic. In this type of attack, multiple compromised systems are orchestrated to flood a target server, service, or network with an overwhelming volume of requests. The goal is to exhaust the resources of the targeted system, ultimately leading to a denial of service for legitimate users. During such an attack, the system becomes unable to respond to legitimate requests, effectively disrupting normal operations.

The other options are focused on aspects that do not align with the intent of a DDoS attack. For instance, increasing network bandwidth is not the objective; rather, the attack seeks to strain available bandwidth. Enhancing security protocols is contrary to the nature of a DDoS attack, as it aims to cripple service availability rather than improve security. Accessing confidential data is also not the primary aim, as DDoS attacks typically do not involve data theft but rather the disruption of services.
