Abstract

An information processing apparatus determines, when a data transmission is executed, whether or not a host name designated as a destination of the data transmission is set to a terminal list indicating an external terminal that is permitted as a data transmission destination, and if a result of the determination is that the host name is set to the terminal list, permits data transmission irrespective of whether or not an IP address corresponding to the host name is set to the terminal list; and executes data transmission if data transmission is permitted.

Claims

1. An information processing apparatus comprising:

a processor; and

a memory storing instructions which, when executed by the processor, cause the information processing apparatus to;

determine, when a data transmission is executed, whether or not a host name designated as a destination of the data transmission is set to a terminal list indicating an external terminal that is permitted as a data transmission destination;

permit, in a case where a result of the determination is that the host name is set to the terminal list, data transmission irrespective of whether or not an IP address corresponding to the host name is set to the terminal list;

determine, in a case where the result of the determination is not that the host name is set to the terminal list, whether or not the IP address designated as the destination of the data transmission is set to the terminal list;

permit, if a result of the determination is that the IP address is set to the terminal list, the data transmission; and

execute data transmission if data transmission is permitted.

2. The information processing apparatus according to claim 1, further comprising an interface configured to receive a host name and an IP address indicating an external terminal that is permitted as a data transmission destination, wherein the instructions, when executed by the processor, further cause the information processing apparatus to set the host name and the IP address to the terminal list.

3. The information processing apparatus according to claim 1, wherein the instructions, when executed by the processor, further cause the information processing apparatus to:

prohibit, if a result of the determination is the IP address is not set to the terminal list, data transmission.

4. The information processing apparatus according to claim 1, wherein the instructions, when executed by the processor, further cause the information processing apparatus to:

in a case where the result of the determination is not that the host name is set to the terminal list, determine whether or not an IP address designated as a destination of the data transmission is set to the terminal list, and

permit, if a result of the determination is that the IP address is set to the terminal list, data transmission, and prohibit, if a result of the determination is that the IP address is not set to the terminal list, data transmission.

5. The information processing apparatus according to claim 3, wherein the instructions, when executed by the processor, further cause the information processing apparatus to discard data relating to the data transmission if the data transmission is prohibited.

6. The information processing apparatus according to claim 1, wherein the instructions, when executed by the processor, further cause the information processing apparatus to:

acquire, by querying a DNS server that is communicable via a network, an IP address corresponding to the host name; and

execute data transmission using the acquired IP address.

7. The information processing apparatus according to claim 6, wherein the IP address corresponding to the host name is the acquired IP address.

8. The information processing apparatus according to claim 2, wherein the interface receives, by a user input via a screen by which a host name and an IP address are individually inputtable, information that is input in the terminal list.

9. An information processing apparatus comprising:

an interface that receives a host name or an IP address from a user for specifying an external terminal that is permitted as a data transmission destination;

a storage that stores, as permission information indicating an external terminal that is permitted as a data transmission destination, the host name or the IP address received by the interface; and

a controller that permits execution of data transmission in a case where a host name is received as a destination of a data transmission and the received host name is included in the permission information, determines whether or not an IP address corresponding to the received host name is included in the permission information in a case where the host name is received as a destination of a data transmission and the received host name is not included in the permission information, and permits execution of data transmission if a result of the determination is that the IP address is included in the permission information.

10. The information processing apparatus according to claim 9, wherein, in a case where a host name is received as a destination of a data transmission, the controller prohibits execution of data transmission under a condition that neither the received host name nor an IP address corresponding to the received host name is included in the permission information.

11. The information processing apparatus according to claim 9, wherein, in a case where an IP address is received as a destination of data transmission, the controller permits execution of data transmission under a condition that the received IP address is included in the permission information, and does not permit execution of data transmission under a condition that the received IP address is not included in the permission information.

12. The information processing apparatus according to claim 9, wherein the information processing apparatus executes, in a case where execution of data transmission is permitted by the controller, the data transmission.

13. A method of controlling an information processing apparatus, the method comprising:

determining, when a data transmission is executed, whether or not a host name received as a destination of the data transmission is set to a terminal list indicating an external terminal that is permitted as a data transmission destination;

in a case where a result of the determination is that the host name is set to the terminal list, permitting data transmission irrespective of whether or not an IP address corresponding to the host name is set to the terminal list;

determining, in a case where the result of the determination is not that the host name is set to the terminal list, whether or not the IP address designated as a destination of the data transmission is set to the terminal list;

permitting the data transmission if a result of the determination is that the IP address is set to the terminal list and

executing data transmission if data transmission is permitted.

14. A method of controlling an information processing apparatus, the method comprising:

receiving a host name or an IP address from a user for specifying an external terminal that is permitted as a data transmission destination;

storing, as permission information indicating an external terminal that is permitted as a data transmission destination, the received host name or the received IP address;

permitting execution of data transmission in a case where a host name is received as a destination of a data transmission and the received host name is included in the permission information;

determining whether or not an IP address corresponding to the received host name is included in the permission information in a case where the host name is received as a destination of a data transmission and the received host name is not included in the permission information; and

permitting execution of data transmission if a result of the determination is that the IP address is included in the permission information.

15. A non-transitory computer-readable storage medium on which is stored code of a computer program for causing a computer to execute a method for controlling an information processing apparatus, the method comprising:

determining, when a data transmission is executed, whether or not a host name received as a destination of the data transmission is set to a terminal list indicating an external terminal that is permitted as a data transmission destination;

in a case where a result of the determination is that the host name is set to the terminal list, permitting data transmission irrespective of whether or not an IP address corresponding to the host name is set to the terminal list;

in a case where the result of the determination is not that the host name is set to the terminal list, determining whether or not the IP address designated as a destination of the data transmission is set to the terminal list;

permitting the data transmission if a result of the determination is that the IP address is set to the terminal list; and

executing data transmission if data transmission is permitted.

16. A non-transitory computer-readable storage medium on which is stored code of a computer program for causing a computer to execute a method for controlling an information processing apparatus, the method comprising:

receiving a designation of a host name or an IP address from a user for specifying an external terminal that is permitted as a data transmission destination;

storing, as permission information indicating an external terminal that is permitted as a data transmission destination, the received host name or the received IP address;

permitting execution of data transmission in a case where a host name is received as a destination of a data transmission and the received host name is included in the permission information;

determining whether or not an IP address corresponding to the host name is included in the permission information in a case where the host name is received as a destination of a data transmission and the received host name is not included in the permission information; and

permitting execution of data transmission if a result of the determination is that the IP address is included in the permission information.
