ZYX company experienced a DoS/DDoS attack on their network. Upon investigating the incident, they concluded that the attack is an application-layer attack. Which of the following attacks did the attacker use?
Correct Answer: A
The Slowloris attack is a type of application-layer attack that targets the web server by establishing and maintaining many simultaneous HTTP connections to the target server. Unlike traditional network-layer DoS/DDoS attacks such as UDP flood or SYN flood, Slowloris is designed to hold as many connections to the target web server open for as long as possible. It does so by sending partial requests, which are never completed, and periodically sending subsequent HTTP headers to keep the connections open. This consumes the server's resources, leading to denial of service as legitimate users cannot establish connections. The Slowloris attack is effective even against servers with a high bandwidth because it targets the server's connection pool, not its network bandwidth.References:Incident Handler (ECIH v3) courses and study guides particularly emphasize understanding different types of attacks, including application-layer attacks like Slowloris, as part of the incident handling and response process.
