SECURITY POLICY SETTING METHOD IN VIRTUAL COMMUNICATION NETWORK, SECURITY POLICY MANAGER AND VIRTUAL COMMUNICATION NETWORK SYSTEM USING IT

摘要

PROBLEM TO BE SOLVED: To provide a security policy setting method by which even a person not having much intelligence about security policy can automatically set the security policy by having only to make a simple operation on a menu without paying attention to a communication condition and to provide a security policy manager and a communication network. SOLUTION: In this security policy setting method, a plurality of communication terminals that are objects of a virtual network to be built up are selected on a menu where a network map is displayed to specify a setting range. A communication condition to be set is selected from a security policy information storage table in which a communication condition including an encryption algorithm is stored in advance in crow-reference with a specified setting range (S102). Thus, communication paths required for the network are retrieved in response to the specified setting range and the selected communication condition, communication terminals being components of the respectively retrieved communication paths are retrieved furthermore, and a communication condition selected from the security policy information storage table is sequentially and automatically set in response to the respective communication terminals.
