authenticating the request using a security provider which is different from the security provider corresponding to the requested function.

8. A method of setting security policy of an image forming apparatus which is connectable to an external device via a communication interface and includes an open framework on which applications corresponding to a plurality of functions are installed, the method comprising:

receiving a command to change the security policy of the image forming apparatus;

displaying the security policy set for the image forming apparatus and security providers installed in the image forming apparatus;

selecting at least one of the displayed security providers; and

setting the selected security provider as a user authenticator for the plurality of applications.

9. The method according to claim 8, further comprising:

selecting at least one application to apply the selected security provider,

wherein in the setting of the selected security provider, the selected security provider is set as the user authenticator for the at least one selected application.

10. The method according to claim 8, further comprising:

selecting a security mode,

wherein in the setting of the selected security provider, the selected security provider is set as the user authenticator for the at least one selected application according to the selected security mode.

11. The method according to claim 10, wherein the security mode includes at least one of a first security mode in which authentication is not performed, a second security mode in which authentication is performed using a single security provider, and a third security mode in which authentication is performed using a plurality of security providers.

12. The method according to claim 8, wherein the command to change the security policy is received through at least one of the external device and a user interface window of the image forming apparatus.

13. An image forming apparatus which is connectable to an external device and includes an open framework on which applications corresponding to a plurality of functions are installed, the image forming apparatus comprising:

a communication interface unit to access the external device storing at least one security provider corresponding to user authentication;

a user interface (UI) unit to select the security provider;

a storage unit to receive the selected security provider from the external device and store the received security provider;

a control unit to install the stored security provider in the image forming apparatus, select at least one application to apply the installed security provider, and set the installed security provider as a user authenticator for the at least one selected application.

14. The image forming apparatus according to claim 13, wherein the UI unit displays the stored security provider, and the control unit installs a security provider selected from the displayed security provider in the image forming apparatus.

15. The image forming apparatus according to claim 13, wherein the control unit sets the installed security provider as the user authenticator for the selected application using security information corresponding to the at least one selected application.

16. The image forming apparatus according to claim 13, wherein the storage unit maps the at least one selected application onto the installed security provider and stores mapping information as a database.

17. The image forming apparatus according to claim 13, wherein the UI unit displays a first UI window to select the security provider installed in the image forming apparatus, and when the security provider is selected through the first UI window, the UI unit displays a second UI window to select an application to perform authentication using the selected security provider, and

wherein when the application is selected through the second UI window, the control unit changes the security policy to authenticate using the selected security provider when the selected application operates.

18. The image forming apparatus according to claim 13, wherein the UI unit displays a first UI window to select the security provider installed in the image forming apparatus, and

wherein when the security provider is selected through the first UI window, the control unit changes the security policy to authenticate using the selected security provider when the plurality of applications operate.

19. The image forming apparatus according to claim 13, wherein the control unit determines if the stored security provider is suitable for the image forming apparatus, and when the stored security provider is suitable for the image forming apparatus, the stored security provider is installed in the image forming apparatus.

20. The image forming apparatus according to claim 13, wherein the communication interface unit or the UI unit receives a request to perform a function provided by the image forming apparatus, and the control unit performs authentication for the request using a security provider corresponding to the requested function, and provides the requested function using an application corresponding to the request when the request is authenticated.

21. A method of setting security policy of an image forming apparatus, the method comprising:
