D

Denial of Service (DoS) Attack

A type of attack that attempts to make an online service unavailable by flooding the target with more requests than it can handle, usually from a single source.

Distributed Denial of Service (DDoS) Attack

A type of attack that attempts to make an online service unavailable by flooding the target with more requests than it can handle. Unlike a DoS attack that typically comes from a single source, in a DDoS attack attackers use multiple compromised devices to generate traffic from many sources simultaneously.
