DDoS Overview by Best Engineering Colleges in India CS and IT Professors

DDoS i.e. Distributed Denial of Service attack refers to a special type of DOS attack, in which large numbers of compromised systems infected because of Trojan used to target only one system to cause DoS or Denial of Service attack. Victims of this attack comprise of an end-targeted system and various other systems used in malicious way and controlled with the help of hacker within distributed attack.

Mechanism of DDoS

Now, the article will look over the mechanism of DDoS, as explained by CS and IT experts of best engineering colleges in India. In any DDoS attack, incoming traffic that floods the victim actually originates from large numbers of sources i.e. potentially hundreds, thousands and even more.

This activity effectively causes stopping of the attack almost impossible by simply blocking a particular IP address. Moreover, DDos makes distinguishing of attack traffic from user traffic difficult whenever it spreads across large numbers of origin points.

How Dos is Different from DDoS

Before a person step ahead to understand the difference in between DoS and DDoS, it is essential to get a briefing about DoS, as mentioned here by best engineering colleges in India professors.

·         What is DoS

DoS is the abbreviated form of Denial of Service Attack i.e. a particular type of network’s attack designed to bring the entire network into its knees via flooding it with the help of various useless traffic. This type of attack typically utilizes a single computer and only one connection to flood a specific targeted system or a specific resource.

·         Difference

DDoS attack is different because of the fact that DDoS uses more than one connection of internet and computer systems to flood specific targeted resource. In addition, unlike DoS, distributed type of denial service attacks are of global attacks distributed by the help of botnets.

Types of Attacks

Until now, professional team associated with best engineering colleges in India have found and reported about few major categories of DDoS attacks, which include

·         Traffic Attacks

Traffic flooding attacks are responsible for transmission of TCP, ICPM and UDP packets towards the target. In this case, as legitimate requests lost, malware exploitations accompany such attacks and flood the network.

·         Bandwidth Attacks

These attacks are mainly responsible for overloading of the target via targeting of junk data in massive amounts. This type of attack leads to loss of entire network bandwidth as well as resources of the equipment. In addition, bandwidth attacks result in entire denial of services.

·         Application Attacks

Messages of application data layer mostly deplete resources present in application layer to leave to the services offered by any target system as unavailable.
