HTTP denial of service (DoS) attack is a type of cyber attack where an attacker floods a web server with a large number of HTTP requests, overwhelming its resources and causing it to become unresponsive or unavailable to legitimate users.
The attack works by exploiting vulnerabilities in the server’s software or infrastructure, such as exploiting weaknesses in its processing power or network bandwidth. This can include sending multiple requests for large files or submitting information through web forms or cookies, which can consume server resources and make it unavailable to legitimate users.
Attackers can also use botnets, which are networks of malware-infected devices that can be controlled remotely, to launch an HTTP DoS attack. By using a botnet, the attacker can generate a large number of requests simultaneously, overwhelming the server even faster.
HTTP DoS attacks can have serious consequences, including loss of revenue, brand damage, and even legal consequences. Organizations can prevent or mitigate these attacks by implementing security measures, such as firewalls, intrusion detection systems, and load balancers, and regularly testing their systems for vulnerabilities.
