What is HTTP GET attack?
An HTTP flood DDoS attack utilizes what appear to be legitimate HTTP GET or POST requests to attack a web server or application. These flooding DDoS attacks often rely on a botnet, which is a group of Internet-connected computers that have been maliciously appropriated through the use of malware such as a Trojan Horse.
What is HTTP DDoS?
HTTP flood is a type of Distributed Denial of Service (DDoS) attack in which the attacker exploits seemingly-legitimate HTTP GET or POST requests to attack a web server or application. This makes HTTP flood attacks significantly harder to detect and block.
How do you mitigate a HTTP attack?
Other avenues for stopping HTTP floods include the use of a web application firewall (WAF), managing an IP reputation database in order to track and selectively block malicious traffic, and on-the-fly analysis by engineers.
How are HTTP GET requests used in the web?
HTTP GET requests are used to request data from the web server. For example, when you enter a website URL in your web browser, you instruct the browser to send an HTTP GET request to the web server that hosts the website. The server then returns the response, and the browser renders it.
Are there any other ways to attack the HTTP protocol?
This attack is usually following the HTTP protocol standards to avoid mitigation using RFC fcompliancy checks. Other HTTP methods – other than the common GET method, the HTTP protocol allows other methods as well, such as HEAD, POST and more.
How are misbehaved fields used in http attacks?
HTTP fuzzers and misbehaved fields – these attacks are sending garbage or bad values on specific HTTP protocol fields. The attack will send a G3T request (instead of a GET request), send traffic on HTTP version 1,1 (instead of HTTP 1.1) and so on.
What kind of attack would send a G3T request?
The attack will send a G3T request (instead of a GET request), send traffic on HTTP version 1,1 (instead of HTTP 1.1) and so on. Another option is to use random values in the field place in the communication. The attackers are trying to crash the web server, which will happen if the server is not checking for the validity of these input values.
