An enclosed virtual honeynet,which is fit for debugging,is implemented,and the validity reliability and stability of the virtual honeynet are proved.

The Research and Design of Virtual Honeynet System;

This paper presents a novel way for building virtual honeynet based on Xen virtual machine monitor, thus to considerably improve the invisibility and raise the difficulty for attackers to discover.

First the definition and catego-ries of Honeypot are presented, then the security values of Honeypot are researched, and the correlative concepts andprinciples of Honeynet and Virtual Honeynet are discussed.

This paper describes a robot calibration approach,which forms a virtual closed kinematic chain by using a laser.

This paper in connection with that Honeyd can create a large number of virtual honeypot in one physical machine,Analyzes how to create virtual honeypot based on linux from the logical structure, the different network packet processing, and the realization of the scripting language.

Aiming at the need of teaching and experiment in computer network and information security in university and college,this article proposed how to construct a virtual network security experimental platform that combines the virtual software,the virtual honeypot,the network sniffer and analysis techniques.

For example,a close loop of the train control information transmitted by radio,such as cab-signaling,position and speed of the train can be confirmed;utilization of the virtual block control and the combination of the radio-ba.
