POLICY CREATION METHOD FOR FACILITATING POLICY CORRECTION ACCOMPANYING SYSTEM CONFIGURATION CHANGE AND POLICY MANAGEMENT METHOD

摘要

PPROBLEM TO BE SOLVED: To facilitate policy rule correction when changing a system configuration. PSOLUTION: A reason for applying a policy rule is set together when the policy rule is created, and it is discriminated whether this reason is satisfied or not when the system configuration is changed. In order to determine influences upon the policy rules of configuration changes, a policy management device preliminarily defines and stores information which associates detailed information of a system configuration management target object with comparison contents of reasons for applying the policy rules and defines the degrees of influences. When detailed information of the management target object is changed by a system configuration change, a configuration management device extracts difference information. The policy management device performs discrimination processing of discriminating whether reasons for applying policy rules which the policy management device itself manages are satisfied or not on the basis of the difference information and lists up policy rules which are influenced by the configuration change, with detailed causes and the degrees of influences, whereby user's policy correction is facilitated.
