Distributed DoS attack. A distributed denial-of-service (DDoS) attack occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers. Such an attack is often the result of multiple compromised systems (for example, a botnet) flooding the targeted system with traffic.

.

Similarly, it is asked, how does a DDoS attack work?

The DDoS attack will attempt to make an online service or website unavailable by flooding it with unwanted traffic from multiple computers. The attacker can then instruct and control the botnet, commanding it to flood a certain site with traffic: so much that its network ceases to work, taking the site offline.

Additionally, what are the types of DDoS attacks? Broadly speaking, DoS and DDoS attacks can be divided into three types:

  • Volume Based Attacks. Includes UDP floods, ICMP floods, and other spoofed-packet floods.
  • Protocol Attacks. Includes SYN floods, fragmented packet attacks, Ping of Death, Smurf DDoS and more.
  • Application Layer Attacks.
