Which term describes an attack that floods a site with traffic to overwhelm it?

• A. DDoS
• B. APT
• C. Blacklisting
• D. Whitelisting

Answer: (A)

Flooding a site with traffic to overwhelm its resources is a denial-of-service attack. When the flood comes from many different machines, it becomes a distributed denial-of-service attack, or DDoS. The goal is to exhaust bandwidth or server resources so legitimate users can’t access the service. This is different from other terms: an advanced persistent threat is a long-term, stealthy intrusion; blacklisting blocks known bad actors; whitelisting allows only approved entities. So the best term for a traffic-flooding attack is DDoS.
