Let us start with a news section, denial of service, also called Hazardous.
In this lecture, we will have an overview to what is denial of service or denial of service attack
also to the doctor, that is a cyber attack in which the hacker seeks to make a machine on network resource
unavailable to its intended users by temporarily or indefinitely disrupting services of who's connected
to the Internet.
Denial service is typically accomplished by flooding the targeting machine or resource with a superfluous
request.
Or you can see actually bogus or unwanted requests in an attempt to overload systems and prevent some
or all legitimate requests from being fulfilled.
Now, in a distributed denial of service, that is, the details attack.
The incoming traffic from the victim originates from many different sources.
This effectively makes it impossible to stop the attacks simply by blocking a single source.
But does other details.
Attack is analogous to a group of people crowding the entry door of a shop, making it harder for legitimate
customers to enter, therefore disrupting the trade.
Criminals often often targets sites or services posted on high profile Web servers such as banks or
credit card payment gateways.
Revenge blackmail activism can motivate these types of attacks.
A denial of service attack is any type of attack that prevents individuals from accessing a particular
resource or service.
Essentially, the attack affects the availability of Internet or network based services, which hurts
under the golden and information security that the CIA tried, which stands for confidentiality, integrity
and availability.
This is why information security professionals care about this DOS attack and constantly determine methods
mediated.
Well, on your screen you can see that there is a hacker who has compromised the command and control
server on that server.
There are various bottlenecks and also Hacker has compromised all those computer systems, also called
as botnet.
And now these partners are floating a particular victims server or also you can call a particular victim's
computer system.
Therefore, the system will crash and the hacker is successful in getting autodidacts or attack.
In the next lecture, we will see categories of DOS attack.
