Abstract

A method for updating information on security , in which the client is connected with a server through a network, the server including a storage device that is managed by the client, the storage device storing security information, the method comprising updating the security information stored in the storage device that the client manages in the server.

Claims

1. A method for updating information on security, in which said client is connected with a server through a network, said server including a storage device that is managed by said client, said storage device storing security information, said method comprising:

updating said security information stored in said storage device that said client manages in said server.

2. A method for updating information on security according to claim 1, wherein said client does not include a local disk device.

3. A method for updating information on security according to claim 1, wherein said server is connected to a management computer through said network and wherein said updating said security information is conducted by said management computer.

4. A method for updating information on security according to claim 1, wherein said storage device that said client manages in said server stores files that said client uses, and wherein said security information includes attributes relating to said files that said client uses.

5. A method for updating information on security according to claim 4, wherein said security information includes access control information with respect to said files that said client uses.

6. A method for updating information on security according to claim 1, wherein said client references said security information of said client.

7. A method for updating information on security according to claim 6, wherein said security information includes authentication information for permitting use of said client by a user.

8. A client connected to a server through a network, said server including a storage device, comprising:

a unit managing said storage in said server, said storage device storing security information, said security information being updated without operation of said client; and

a unit referencing said security information.

9. A client according to claim 8, wherein said client does not include a local disk device.

10. A client according to claim 8, wherein a management computer is connected to said server through said network and said security information of said client is updated by said management computer.

11. A client according to claim 8, wherein said storage device that said client manages in said server stores files that said client uses, and wherein said security information includes attributes relating to said files that said client uses.

12. A client according to claim 11, wherein said security information of said client includes access control information with respect to said files that said client uses.

13. A client according to claim 8, wherein said security information includes authentication information for permitting use of said client by a user.

14. A server connected to a client through a network comprising:

a unit communicating with said client through said network; and

a storage device that is managed by said client, said storage device storing security information to be updated.

15. A server according to claim 14, wherein said client does not include a local disk device.

16. A server according to claim 14, wherein a management computer is connected to said server through said network and said security information is updated by said management computer.

17. A server according to claim 14, wherein said storage device stores files that said client uses, and wherein said security information includes attributes relating to said files that said client uses.

18. A server according to claim 17, wherein said security information includes access control information with respect to said files that said client uses.

19. A server according to claim 14, wherein said security information is referenced by said client.

20. A server according to claim 19, wherein said security information includes authentication information for permitting use of said client by a user.

21. A management computer connected through a network to a server, said server including a storage device that is managed by a client, said storage device storing security information of said client, comprising:

a unit communicating with said server through said network; and

a unit updating said security information of said client.
