• A. Distributed Definition of Service
• B. Distributed Denial of Service
• C. Digital Denial of Service
• D. Dynamic Denial of Service

Answer: (B)

DDoS stands for Distributed Denial of Service. In cybersecurity, this term is used to describe an attack where multiple compromised systems are used to flood a target with excessive traffic, overwhelming its resources and rendering it unable to respond to legitimate requests. The "distributed" aspect refers to the attack being launched from numerous sources—usually a botnet made up of many infected devices—making it difficult to defend against or mitigate due to the volume of incoming requests that can come from various locations.

The focus of a DDoS attack is to deny service to legitimate users by disrupting the normal functioning of a target, such as a website or online service. This tactic can be employed for various reasons, including extortion, political motives, or simply to cause chaos.

Understanding the nature of a DDoS attack is crucial for cybersecurity professionals, as it informs their strategies for preventing and responding to such threats. Additionally, knowing the correct terminology is essential for effective communication within the field, as it helps align team efforts and responses to incidents.
