Hey you guys?! Whats up !! Today I'll be discussing a new term. Its called DDos and its a very common type of attack that hackers use while hacking into a system or while a hacker tries to bring down the system. Many TV series bring up the topic DDos. Its one of the most basic term that every computer enthusiast must know. A denial-of-service (Dos) attack is an attempt to make a machine or network resource available to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the internet. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fullfilled.
A distributed denial-of-service (DDos) is where the attack source is more than one, often thousands of, unique IP addresses. It is analogous to a group of people crowding the entry door or gate to a shop or business, and not letting legitimate parties enter into the shop or business, disrupting normal operations. The scale of DDos attacks has continued to rise over recent years, even reaching over 600Gbit/s.
An example of Dos is:
:(){:|:&};: //If you type this in terminal of a linux machine, the OS will crash.
OR
:1
start
goto 1
If you type this in notepad and save it as a .bat file and run it, your OS will not be able to respond, it'll crash
Let me explain DDos in a nutshell. Assume you are in a restaurant that is not that big. So if you call the waiter he'll take your order and give it to the chef right? Now assume there is only one waiter and there are 100 of people giving him their order. The waiter can't possibly complete all your requests and will ask for a time out. Well thats the basic of DDos. In this scenario you're the client and the waiter is the server. Put the logic in the above context and you'll understand what DDos is. There are many types of Dos attacks but I can't discuss all of them since I don't know all of them. But the basic is the same most of them.
Well thats all for today's article. Hope you got a lot of info on the topic Dos. See you next time.
