DDoS (Distributed Denial of Service) attack is an attempt to overload and disrupt the normal functioning of a server, service, or network by overwhelming it with traffic from multiple sources. In this type of attack, the attacker uses a group of devices infected with malware, commonly known as a “botnet” to bombard the target continuously with more requests than it can handle, which causes the server resources to run out and slow down or completely block legitimate users.
