CYBER ATTACK PRACTICE SYSTEM, PRACTICE ENVIRONMENT PROVIDING METHOD, AND, PRACTICE ENVIRONMENT PROVIDING PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent virtual environments of practicing persons from being influenced on each other and to safely perform practices when constructing the virtual environment for cyber attack practices.SOLUTION: A physical server 10 includes: a physical port 111 for exchanging management information with an instructor terminal 30; and a physical port 112 for a host group within the physical server 10 to communicate with an external network via an L3 switch 20. For each practicing terminal 40 that performs cyber attack practices, the physical server 10 constructs a virtual network connecting host groups and hosts to be used for practices with each other. A port control section 124 is included by which, when any abnormality occurs in a practice environment, by making the physical port down on the basis of instruction input from the instructor terminal 30, such that influences on the external network are prevented. To the L3 switch 20 connected to the physical server 10, access control is set so as to prevent a host group from communicating with a host group of another practicing terminal 40.
