What is the main method used by the Slowloris attack?

• A. Sending numerous complex queries
• B. Sending incomplete HTTP requests
• C. Blocking IP addresses
• D. Using phishing tactics

Answer: (B)

The Slowloris attack primarily relies on sending incomplete HTTP requests to target a web server. This method exploits the way web servers handle incoming requests by initiating connections and then deliberately not completing them. When a Slowloris attack is executed, it opens a connection to the server and sends partial HTTP headers, causing the server to wait for the completion of the requests. Since web servers typically have a limited number of connections they can maintain at any one time, this tactic gradually exhausts server resources, preventing legitimate users from establishing new connections. This technique is particularly effective against servers that do not have adequate protections in place, as it allows the attacker to keep the connection alive for an extended period without actually sending all the required data. As a result, legitimate requests are denied, leading to a denial-of-service condition.
