In this article I am trying to explain what DDOS is and how it can be prevented. DDOS happens due to lack of security awareness of the network/server owners. On a daily basis we hear that a particular machine is under DDOS attack or NOC has unplugged the machine due to DDOS attack . So DDOS has become one of the common issues in this electronics world. DDOS is like a disease which doesn’t have an anti-viral developed. So we should be carefull while dealing with it . Never take it lightly. In this article i am trying to explain the steps/measures which will help us defend from DDOS attack ,up to a certain extend .

What is a DDOS attack?

Simply said, DDOS is an advanced version of DOS attack . Like DOS , DDOS also tries to deny the important services running on a server by broadcasting packets to the destination server in a way that the Destination server cannot handle it. The speciality of the DDOS is that, it relays attacks not from a single network/host like DOS. The DDOS attack will be launched from different dynamic networks which has already been compromised.

Normally, DDOS consists of 3 parts . One is the Master ,Other the slave and atlast the victim. The master is the attack launcher ie the person/machine behind all this,sound’s COOL right . The slave is the network which is being compromised by the Master and Victim is the target site/server . Master informs the compromised machines, so called slaves to launch attack on the victim’s site/machine. Hence its also called co-ordinated attack.

In my term, Master is said to be the Master Brain, Slave is said to be the launch pad for the attack and Victim is the target.
