SECURITY MANAGEMENT SYSTEM, RELAY DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To execute application of a security patch without depending on setting of an OS by preventing connection of a terminal having a security hole to the Internet, and detecting the security hole without introducing management software to each terminal. SOLUTION: The function of inspecting presence/absence of security hole is given to a router of an internal network within a company or a house to perform inspection of presence/absence of security hole to terminals on the internal network to access to an external network, and a terminal in which security holes are entirely blocked is determined as success. Communication with the external network is permitted only to terminals which succeeded in the inspection without restriction, but limited for terminals not succeeded in the inspection.
