What is a DDoS Attack?

A distributed denial-of-service (DDoS) attack is an attempt which multiple compromised computer systems or devices attack a target, such as a server, website or other network resource, and cause the online service unavailable to users, usually by temporarily interrupting or suspending the services of its hosting server. Through the exploitation of millions of insecure Internet-of-Things (IoT) devices, the creation of botnets waging highly distributed volumetric attacks is easier and more impactful than ever before.

Types of DDoS Attacks

Volume Based Attacks
Includes UDP floods, ICMP floods, and other spoofed-packet floods. The attack’s goal is to saturate the bandwidth of the attacked site, and magnitude is measured in bits per second (Bps).

Protocol Attacks
Includes SYN floods, fragmented packet attacks, Ping of Death, Smurf DDoS and more. This type of attack consumes actual server resources, or those of intermediate communication equipment, such as firewalls and load balancers, and is measured in packets per second (Pps).

Application Layer Attacks
Includes low-and-slow attacks, HTTP GET/POST floods, attacks that target Apache, Windows or OpenBSD vulnerabilities and more. Comprised of seemingly legitimate and innocent requests, the goal of these attacks is to crash the web server, and the magnitude is measured in Requests per second (Rps).
