Information processor having multi OS and its OS update method
First Claim
1. An OS (operating system) update method that updates an OS installed in an information processor, comprising the steps of:
- determining whether an update of a front end OS that controls usual application processing is necessary;
terminating the processing of the front end OS in operation and switching the control of the information processor to a back end OS when it is determined that the update of said front end OS is necessary;
acquiring update data for updating the front end OS in the latest state under the control of the back end OS and updating the front end OS updated in the latest state; and
restarting the front end OS updated in said latest state.

Abstract
The present invention provides an art that can update an OS (Operating System) of an information processor efficiently. An OS update method that updates the OS installed in the information processor has the steps of determining whether an update of a front end OS that controls usual application processing is necessary, terminating the processing of the front end OS in operation and switching the control of the information processor to a back end OS, acquiring update data for updating the front end OS in the latest state under the control of the back end OS when it is determined that the update of the front OS is necessary, updating the front end OS in the latest state, and restarting the updated front end OS in the latest state.

4. A security control method that controls security of application processing executed in an information processor having a multi OS, comprising the steps of:
-
inquiring whether an application processing request made on the information processor is permitted when the application processing request is made;
responding to an inquiry result that indicates determination contents after determining whether said inquired processing request is permitted in accordance with a management policy; and
executing the application processing when the contents of said inquiry result indicate the execution permission of said application processing. - View Dependent Claims (5, 6, 7)

8. An information processor that updates an OS installed in the information processor, comprising:
-
front end OS up-data that determines whether a front end OS that controls usual application processing must be updated, acquires update data for updating the front end OS in the latest state under the control of a back end OS, and updates the front end OS in the latest state; and
a multi OS configuration part that terminates processing of the front end OS in operation and switches control of the information processor to the back end OS, and then restarts the front OS updated in said latest state when it is determined that said front end OS must be updated.

9. An information processor that controls security of application processing executed in the information processor having a multi OS, comprising:
-
a security agent that sends to a security check processing part an inquiry as to whether an application processing request is permitted when the application processing request is made on the information processor and executes the application processing when contents of said inquiry result indicate the execution permission of said application processing; and
the security check processing part that responds to the security agent with an inquiry result that indicates determination contents after determining whether said inquired processing request is permitted in accordance with a management policy.

10. A method for updating the first OS in an information processor having the first OS that controls application processing and the second OS that is executed as a backend OS against the first OS, comprising:
-
determining whether an update of the first OS is necessary;
requiring to an destination relating to the first OS for acquiring an information regarding updating the first OS;
changing the control of the information processor to the second OS when the update of said first OS is necessary;
acquiring update information for the first OS under the control of the second OS; and
changing the control of the information processor to the first OS when the update information for the first OS is acquired. - View Dependent Claims (11, 12, 13, 14, 15)

16. An information processor having a multi OS, comprising;
-
a memory having the first area for storing the first OS that controls application processing, the second area for storing the second OS that is executed as a backend when the first OS is at least updated and a multi OS configuration part that communicates between the first OS and the second OS;
a CPU for processing the application under the control of the first OS;
a communication unit that coupled the information processor to a network;
changing means for changing from the first OS to the second OS to control the information processor when the change of the first OS is necessary;
acquiring means for acquiring an updated information for the first OS via said communication unit under control of the second OS; and
means for operating the first OS vie said multi OS configuration part when the acquiring the updated information for the first OS is finished. - View Dependent Claims (17, 18, 19, 20)
