Abstract:

Most security technologies are designed to prevent unauthorized activities for resources. And security tools are put into place as a defensive measure . Therefore there are some shortcomings in network protection. After analyzing the research situation and the shortcomings of security tools in intrusio n detection and system protection, a distributed virtual honeynet system is studied and implemented. The system is composed of a Hybrid Virtual Honeynet  and a low-interaction Honeypot. Which reduces the inherent risk of Honeypot, and adds the simulation＇s trueness, and it makes up for the shortcomings   of existing different types of honeypots. As a dynamic security defensive mechanism, it improves effectively the in tegral safety of large-scale networ ks, and is a completely supplement of traditional security mechanisms.

Key words: network security, intrusion detection, honeypot, honeynet
