The attacker floods the target’s web server with a large number of HTTP requests.

HTTP flood: this is the simplest DDoS resource overload attack variant.

Classic DDoS attack patterns on system resources are ping flood, SYN flood, and UDP flood. If these are used for invalid requests, the server will be effectively blocked for regular users. A large network with many devices connected to it can therefore massively impair the target’s bandwidth.Ī DDoS attack targets the resources of a system this way, attackers exploit the fact that the web server can only establish a limited number of connections. The broadcast request is then forwarded from the network router to all connected devices, which causes them all to send a response to the sender address (Pong).

The attacker sends manipulated ICMP Echo Request packets (Ping) to the broadcast address of a network and uses the target’s IP address as the sender address. Smurf attack: this DDoS attack takes advantage of the Internet Control Message Protocol (ICMP), which helps the exchange of information and error reports in computer networks. A typical DDoS attack designed for overloading bandwidth is the Smurf attack. If this capacity is exceeded due to an attack, the corresponding services will no longer be available to other users. A router can only process a certain amount of data at once. DoS and DDoS attacks directly target networks and their respective connecting device. The aim of overloading the bandwidth is to make a computer inaccessible.
