Abstract: The network attack and defense training course is a very important core course for college network security major in colleges and universities.In view of this fact that this course focuses on basic verification experiments and the operation is relatively simple,this paper designed a comprehensive network attack and defense experiment on internet process connection(IPC)pipeline.First,simulate the hacker's attack operation to let students understand the principles and methods of network attack based on principle and method based on IPC pipeline.Second,several measures were proposed on how to defend.Through this experiment,students will be strengthened to master the knowledge points such as password cracking,IPC vulnerability principle and connection method,NC back door(NetCat,a hacker tools) and thus improve students' hand-on practice and network security defense awareness.
