The blocking of malicious traffic in groupware network system is used to prevent the spread and distribution of malicious traffic. The method protecting from malicious traffic in groupware system is designed to handle the malicious traffic of various routes with the internal course of groupware, which leads to lighten the load of security and traffic. It was impossible to block this kind of traffic at the traditional structure. When the protection of the proposed groupware system is performed, there appears to be a great change for the rate of a load factor at the CPU of Backbone Switch which is connected to the internal gateway. The load factor of CPU, which was increased with the traffic, is now remarkably reduced after the internal gateway is set up. This is to show that a lot of malicious traffic pass through the internal network and that network environment is faced to the menace of many malicious traffics. This paper is to show the efficiency of protection of internal gateway proposed in this study, for the rate of CPU of Backbone Switch was about 17% a day, but was dropped up to the 4% after the malicious traffic was removed.
