Italy: 650,000Since its basic attack principle is backlog overflow that depends on the end host connection socket, an obvious end host-based solution is to increase the backlog queue size, and this method has been widely used in most servers. Increasing the backlog queue is usually done by modifying the application's listen () function call and an operating system kernel parameter SOMAXCONN, which is used to set the upper limit of backlog that an application can receive. This method itself cannot be completely considered as an effective method to resist SYN flooding, even in some operating systems that can effectively support super large backlog queue allocation, because attackers can arbitrarily generate datagrams much larger than the backlog supported by their operating systems.8-1 Message: Write a function called display_message (), which prints a sentence indicating what you learned in this chapter.
