A Denial of Service (DoS) attack is a cybar attack in which an attacker makes the resource of the server or website unavailable for legitimate users.It is done by flooding a huge number of bot traffics to the target website or server.
Understanding it through example:
Every website have its a certain rang of bandwith limit. For example example.com website have limit of 100 person visit per second.But what more than 100 person visit that website in every second?
The website will be disrupt and would not load the data and hence will become down . Now lets talk about DDoS attack:
A Distributed Denial of Service (DDos) is a type of DoS attack in which an attacker makes the resource or server or website unavailable to the legitimate user by flooding a huge number of trrafics from multiple end systems.Yes oyu read right , the traffic here comes from the different ip addresses which makes the attack more powerful.
Both these types of attack are dangerous and illegal (if done without the permission of the owner) .
(Note:Types of DOS and DDOS attack will be discussed in next article soon.)
