Distributed Denial of Service Attack (DDoS)
A Distributed Denial of Service Attack is like a DoS attack on steroids! The difference is that the incoming traffic flooding the target originates from multiple sources, not just one. A successful Distributed Denial of Service attack can cripple an organization for an extended period of time and, due to its complexity is far more complex to resolve than a Denial of Service Attack. See botnet, credential stuffing attack.
