摘要:SYN flood application program is one tool can be used to simulate the type ofdenial of service attack SYN flood. Denial of service itself is one of the types ofattacks against the network service that aims to prevent legitimate users to usenetwork services. Scientific Writing explains how a denial of service types andSYN flood works by conducting simulations. This simulation shows thecharacteristics expected from a denial of service type so that the SYN flood canbe traced to how to handle next. Application program that is included inScientific Writing is designed and worked on the Linux operating system, andcompiled using the C programming language that implements the use offacilities NET / 4 in Linux via socket programming.
