SYSTEM FOR VIRUS AND HACKER INVASION PREVENTIVE MECHANISM, INVASION PREVENTION METHOD, AND INFORMATION PROCESSING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a system, an invasion prevention method and an information processing apparatus in which processing is accelerated in a filtering method of communications on a TCP/IP network including filtering of packets and contents.;SOLUTION: In the structure, a filtering means for communications is made independent in the manner of communications by a switch which is controlled by the filtering means itself, the filtering means manages reading and sending of data, and an IP address is not allocated to the filtering means, such that the filtering means reads and sends communication data to be passed. By performing contents filtering, carry-out inhibited data on an internal network are prevented to be leaked to the outside and by multiplexing the filtering means for communications, a load of processing per unit of the filtering means is reduced. Thus, a processing speed is obtained without problem even when contents filtering is performed.;COPYRIGHT: (C)2004,JPO
