What is DDoS (Distributed Denial-of-Service)?

by Bethany Hendricks on Glossary • September 23, 2020

Whereby a DoS mitigation system might throttle rapid and malicious connection attempts from a specific client/IP, a DDoS attack employs multiple clients/IPs in flooding a server with requests. This makes defending against this kind of attack very difficult without taking server(s) completely offline.

Advanced measures, including connection and connection rate limiting and dynamic IP blacklisting, can be employed to minimize the effectiveness of DDoS attacks.

DDoS attacks are often executed using a botnet: a collection of computing devices that are connected and programmed to perform repetitive tasks.
