Introduction
DDoS - Distributed Denial of Service. DDoS is a type DoS attack of systems, which are often infected with a Trojan , are used to target a single system causing a Denial of Service (DoS) attack. Victims of a DDoS attack consist of both the end targeted system and all systems maliciously used and controlled by the hacker in the distributed attack.
Types Of DDoS Attack
1) Traffic Attack
Traffic flooding attacks send a huge volume of TCP, UDP and ICPM packets to the target. Legitimate requests get lost and these attacks may be accompanied by malware exploitation.
2) Bandwidth attacks
This DDos attack overloads the target with massive amounts of junk data. This results in a loss of network bandwidth and equipment resources and can lead to a complete denial of service.3) Application attacks:
Application-layer data messages can deplete resources in the application layer, leaving the target's system services unavailable.How DDoS Attacks Works
In a DDoS attack, the incoming traffic flooding the victim originates from many different sources – potentially hundreds of thousands or more. This effectively makes it impossible to stop the attack simply by blocking a single IP address; plus, it is very difficult to distinguish legitimate user traffic from attack traffic when spread across so many points of origin.
