Network system having external/internal audit system for computer security
First Claim
1. A network system having a network, comprising:
- at least one repeating unit connected to said network;
at least one computer connected to said network through said at least one repeating unit; and
a management unit connected to said network,wherein said management unit has distribution means for distributing an external audit program, by which said repeating unit audits vulnerability of said computer, from said management unit to said repeating unit through said network, andsaid repeating unit has audit control means for executing external audit processing with respect to vulnerability of said computer in accordance with the external audit program which has been distributed from said management unit to determine whether or not said computer has the vulnerability, and separating means for logically separating said computer having been determined to have the vulnerability from said network.

Abstract
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.

10. A network system having a network, comprising:
-
at least one repeating unit connected to said network; at least one computer connected to said network through said at least one repeating unit; and a management unit connected to said network, wherein said management unit includes distribution means for distributing an internal audit program, by which said computer itself audits the vulnerability of said computer, from said management unit to said computer through said network and said repeating installation, said computer includes means for executing internal audit processing with respect to the vulnerability of said computer in accordance with the internal audit program which has been distributed from said repeating unit, and informing said repeating unit of a result of the internal audit processing, and said repeating unit includes audit control means for determining, based on the result of the internal audit processing which has been informed from said computer, whether or not said computer has the vulnerability, and separating means for logically separating said computer having been determined to have the vulnerability from said network. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A network system having a network, comprising:
-
a plurality of repeating units connected to said network for carrying out repeating of communication on said network; a plurality of computers connected to said network, each of said computers being connected to said network through only a corresponding one of said plurality of repeating units; and a management unit connected to said network, wherein said management unit includes distribution means for distributing at least one of an external audit program and an internal audit program, by which said repeating installation audits vulnerability of at least one of said plurality of computers, from said management unit to said repeating units through said network, and said repeating units include 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 said at least one of said plurality of computers in accordance with at least one of the external audit program and the internal audit program which have been distributed from said management unit to determine whether or not said at least one computer has the vulnerability, and separating means for logically separating said computer having been determined to have the vulnerability from said network. - View Dependent Claims (20, 21, 22)
