A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic.
A DDoS attack is like an unexpected traffic jam clogging up the highway, preventing regular traffic from arriving at its destination.
How does a DDoS attack work?
DDoS attacks are carried out with networks of Internet-connected machines.
These networks consist of computers and other devices (such as IoT devices)which have been infected with malware, allowing them to be controlled remotely by an attacker. These individual devices are referred to as bots (or zombies), and a group of bots is called a botnet.
