<p><P>PROBLEM TO BE SOLVED: To provide a network configuration capable of delaying the spread of propagation and minimizing damage from simulation results of propagation states due to differences in network configurations by simulating the propagation states of a pseudo network type virus or network type worm on a network by variously changing network configurations. <P>SOLUTION: When pseudo attach data for simulating an illegal program is received, each of a plurality of terminal devices is transited to a state infected with the illegal program, generates new pseudo attach data for simulating the illegal program, transmits the new pseudo attach data to other terminal apparatus according to a prescribed rule, and when an infection state confirmation request is received, returns the state of its own apparatus in response to the infection state confirmation request. A pseudo attach management apparatus 51 generates the infection state confirmation request, transmits the infection state confirmation request to respective terminal devices and receives the states of the terminal devices responding to the infection state confirmation request from respective terminal devices. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
