Abstract

A policy integrity validating unit validates whether a system model can achieve an objective set up in a policy without violating a constraint set up in the policy when a system model is operated according to a procedure set up in the policy. When the policy integrity validating unit determines that there is no integrity between a policy created by a system administrator and the system model, an alternate policy creating unit creates an alternate policy that replaces the policy created by the system administrator. Upon receipt of the alternate policy, the policy integrity validating unit validates integrity between the alternate policy and the system model. When the policy integrity validating unit determines that there is integrity between the alternate policy and the system model, a policy creating apparatus presents the alternate policy to the system administrator.

Claims18

Dependent claims

A policy creating apparatus that creates a policy applied to a managed system to control autonomous operation of the managed system, the policy creating apparatus comprising:

a policy receiving unit that receives an administrator created policy created by a system administrator;
a model receiving unit that receives a system model obtained by modeling characteristics of the managed system;
a policy validating unit that validates integrity between the administrator created policy received by the policy receiving unit and the system model received by the model receiving unit;
an alternate policy creating unit that creates an alternate policy that replaces the administrator created policy when the policy validating unit determines that there is no integrity between the administrator created policy and the system model;
a policy revalidating unit that revalidates integrity between the alternate policy created by the alternate policy creating unit and the system model;
and
an alternate policy presenting unit that presents the alternate policy to the system administrator when the policy revalidating unit determines that there is integrity between the alternate policy and the system model;
wherein an application example storage unit stores therein an application example in which it is determined that there is integrity between a system and a policy, and
the alternate policy creating unit refers to the application example stored in the application example storage unit when the policy validating unit determines that there is no integrity between the administrator created policy and the system model, and, if there is a corresponding policy that corresponds to the system model, adapts the corresponding policy as the alternate policy.

6 more elements

A computer readable storage medium containing instructions that, when executed by a computer, causes the computer to create a policy applied to a managed system to control autonomous operation of the managed system, the instructions causing the computer to perform:

receiving an administrator created policy created by a system administrator;
receiving a system model obtained by modeling characteristics of the managed system;
validating integrity between the administrator created policy and the system model;
creating an alternate policy that replaces the administrator created policy when it is determined that there is no integrity between the administrator created policy and the system model at the validating;
revalidating integrity between the alternate policy created at the creating and the system model;
and
presenting the alternate policy to the system administrator when it is determined that there is integrity between the alternate policy and the system model at the revalidating.
