This means that one computer and one internet connection is used to flood a server with packets (TCP / UDP). The point of such a denial of service attack is to overload the targeted server’s bandwidth and other resources. This will make the server inaccessible to others.
Example:- In web server most of common service running like http in port no 80. If server running in 1 MBPS speed it mean in normal application 100 live user connect to the server at time.
Now attacker can attack to server with 500 live user request thought Script. Then what happed !! Server not able to handle the request & their stop their services.
What is DOS ? Denial of Service attack .
HTTP DOS. In this image you can see attacker use script that they attack on router & route all traffic to the server. With massive request & server stop their service.
In most respects it is similar to a DOS attack but the results are much, much different. Instead of one computer and one internet connection the DDoS attack utilises many computers and many connections.
Example:- If server running in 10 MBPS speed it mean in normal application 700 live user connect to the server at time.
Now attacker can attack to server with 500 live user request thought Script with every computer. In This case there lakhs request to the server.Then what happed !! Server not able to handle the request & their stop their services.
What is DDOS ? Distributed Denial of Service Attack .
HTTP DDOS. In this image you can see attacker use botnet. Botnet is one kind of a virus that give backdoor access to attacker . The attacker can send one command to their all botnet client(HTTP Bot) to http server request. The reqest of http can send to server in lot’s client in massive. So that call DDOS in this case Client(HTTP Bot) don’t even know that http request has been send form their pc.
HTTP DOS & DDOS TOOLS. DoHTTP. In this tool you can send socket using browser. For more - http://www.socketsoft.net
HTTP DOS & DDOS. Http Attack Slow poison attack https://www.owasp.org/index.php/OWASP_HTTP_Post_Tool
Http DDOS. Http Attack This script use for down Wiki leaks.
Http DOS. Http Attack In this script you can send packet to the destination with lot’s of amount. .
This is only a few tools not a few also there are lot’s of tools for DOS different type of vulnerability different tools. It is depend what is vulnerability in a target.
This just information about DOS & DDOS how it is work.
