Abstract

A purpose of the invention is to accomplish ensuring security and the like when a user program is executed in a cloud environment. The present system comprises a user terminal 2, a public cloud (CL) 3, and an authentication server 1. The CL 3 comprises a server (31) that executes a user program (UP) and a controller 30. The authentication server 1 comprises an authentication control unit 13 and a library 50. The library 50 stores user information (d2), UP information (d3), CL 3 information (d4), server information (d5), and permission information (d1) that manages an association about execution of the UP with the server. The authentication control section 13 performs processes such as a process for generating UP authentication information (F1), a process for generating server authentication information (F2) and a process for determining execution permission with reference to the authentication information (F1, F2) and the permission information (d1) when the UP is executed by the server of the CL 3.

Claims

1. A cloud security management system in which components including a user terminal, a public cloud including a plurality of servers, and an authentication server are connected by a network, wherein a target server for executing a user program and a processing controller for performing a control related to the execution are provided in the public cloud, the authentication server comprises an authentication control unit and a storage unit, the storage unit stores information containing an ID of the user, information containing an ID of the user program, information containing an ID of the public cloud, information containing an ID of the server, and permission information for managing an association about an execution of the user program with a server of the public cloud, and the authentication control unit comprises:

a first processing unit that creates first authentication information for authenticating the user program, and includes the first authentication information in the user program;

a second processing unit that creates second authentication information for authenticating a server of the public cloud, and provides same to the server of the public cloud;

a third processing unit that sets content of the permission information in accordance with an input from the user terminal; and

a forth processing unit that, when the user program is executed in the server of the public cloud, in cooperation with the controller, refers to the first authentication information, the second authentication information and the permission information, and determines whether the user program is permitted to be executed in the server of the public cloud, and if permitted, executes the program.

2. The cloud security management system according to claim 1, wherein the first processing unit of the authentication control unit of the authentication server encrypts the first authentication information with the use of first password information specified from the user terminal, includes the encrypted first authentication information and the first password information in the user program, and when the user program is executed in the server of the public cloud, the controller refers to the ID of the server contained in the second authentication information stored in the server, refers to the first authentication information and first password information included in the user program, decrypts the first authentication information with the use of first password information, refers to the ID of the program contained in the first authentication information, and transmits an authentication request containing the ID of the server and the ID of the program to the authentication server, and a forth processing unit of the authentication control unit of the authentication server refers to relevant permission information with the use of the ID of the server and the ID of the program contained in the authentication request, and determines the execute permission.

3. The cloud security management system according to claim 1, wherein a plurality of first servers that are targets for executing the user program and a plurality of second servers that provides various functions for processing the user program are provided in the public cloud, the second authentication information is stored in each server, and the forth processing unit of the authentication server refers to the first authentication information corresponding to the user program, the second authentication information corresponding to the accessed second server and the permission information and determines a use permission of a function of the second server in cooperation with the controller for every access from the first server to the second server.

4. The cloud security management system according to claim 1, comprising:

a plurality of user terminals; and

a plurality of public clouds, wherein one or more shared servers that become candidates for sharing and executing the a plurality of user programs and the controller that performs a control process for managing the shared servers are provided in the public cloud, an association about an execution of the user program with the shared servers of the public cloud is set in the permission information.

5. The cloud security management system according to claim 1, wherein the authentication server comprises a registration unit and an execution control unit, the registration unit performs a process for storing data of the user program in the storage unit on the basis of an instruction from the user terminal, the execution control unit performs, on the basis of the instruction from the user terminal, in cooperation with the controller, a control process for executing the data of the user program registered in the storage unit in a server of a target public cloud, the first processing unit of the authentication control unit creates first authentication information for authenticating the user program, includes the first authentication information in the user program, and registers same to the storage unit.

6. The cloud security management system according to claim 1, wherein the authentication server comprises a user interface unit that provides a screen to the user terminal, the user can directly specify a target server of the public cloud for executing the user program and a function on the screen by the user interface unit, and the third processing unit sets the content of the permission information in accordance with the specification.

7. The cloud security management system according to claim 1, wherein the authentication server comprises a user interface unit that provides a screen to the user terminal, the user can indirectly specify a target server of the public cloud for executing the user program and a function on the screen by the user interface unit in a selection form of a performance or a fee structure, and in accordance with the specification, the third processing unit determines an association of a target server of the public cloud for executing the user program with the function, and sets the content of the permission information.
