摘要

A network system includes: a plurality of repeating installations connected to the network; a plurality of computers connected to the network, each of the computers being connected to the network through a corresponding repeating installation; and a management unit connected to the network. The management unit includes distribution means for distributing at least one of an external audit program and an internal audit program for defining the processing procedure, by which the repeating installation audits vulnerability of at least one of the plurality of computers, from the management unit to the repeating installations through the network. The repeating installation includes audit control means for carrying out at least one of the external audit processing and the internal audit processing with respect to the vulnerability of the at least one computer in accordance with at least one of the external audit program and the internal audit program which have been distributed from the management unit to judge whether or not the at least one computer has the vulnerability.
