In this article we will know what is Dos Attack & DDos Attack in Hindi? Meaning what is Denial of Service attack and Distributed Denial of Service attack.
What is Denial of Service Attack?
DOS stands for Denial of Service attack. This is a cyber attack that prevents the legitimate user from accessing resources such as network, website, network, email, WiFi, or slows it down.
For example, if a DoS has been done on a website, then a large number of Useless Traffic is sent to the website by a hacker, as if there is a flood of Data Request and that website cannot handle that request and due to which the website is closed. It becomes or becomes slow, that website is made unavailable for the user of that website so that the user cannot access that website.
The website on which this attack is used, a large amount of request is sent at the same time, which is twice the limit of any server. Due to which the server does not handle the Extra Request and the website either shuts down or becomes slow and sometimes it also crashes.
As you know, each server can handle traffic only up to one level, if more traffic is sent than that, the server gets down and then the website works slowly.
Now let's talk about DDOS, DDOS attack also happens in the same way but there is only a slight difference between DOS and DDOS.
What is DDOS?
DOS Attack is done from one computer to one network and one target, but DDOS Attack is done on that target from many different networks.
DDOS means Distributed Denial of Service means in this DOS is distributed, DDOS Attack attacks a target from different networks from many devices and systems.
Now suppose Attacker is targeting a big server, then its Bandwith will also be high, many of its big servers will be at different places, then in such condition one computer will not work, then for this Attackers need many thousands of devices. So for that, by taking the help of Attackers Botnet, they execute this DDOS Attack.
The best example of DDOS Attack is your railway ticket system. You must have booked online railway tickets many times. When Tatkal ticket booking starts and if there is a festival time at that time, millions of people book tickets from different devices and different networks, then many times the server of IRCT becomes so slow because the server of IRCT is so busy. Unable to handle request.
What is Botnet?
Botnet is a device or system that hackers have already hacked, they use it for this type of attack.
