How does a distributed denial-of-service (DDoS) attack operate?

• A. By compressing data to save bandwidth
• B. By overwhelming a target with traffic from multiple sources
• C. By redirecting users to safe websites
• D. By improving server response times

Answer: (B)

A distributed denial-of-service (DDoS) attack operates by overwhelming a target system, such as a server, network, or website, with an excessive volume of traffic. This traffic typically comes from multiple compromised devices, often part of a botnet, which are controlled by the attacker. The goal of the attack is to exhaust the target’s resources, making it difficult or impossible for legitimate users to access the service. By generating traffic from numerous sources, the attack can be highly effective, as it not only increases the amount of data the target must process but also complicates efforts to block the incoming requests. This type of attack highlights the importance of robust network security measures and traffic management solutions to withstand and mitigate such overwhelming traffic surges.
