Abstract
An information processing apparatus which is capable of preventing unauthorized access thereto. The information processing apparatus is capable of communicating with a server. An inquiry is made of the server about an IP address of the information processing apparatus, which is managed by the server. When it is determined that the IP address obtained from the server as a result of the inquiry and an IP address stored in the information processing apparatus match each other, a warning that a security level of the information processing apparatus is low is issued.
Claims15
An information processing apparatus capable of communicating with a server, comprising:
- a network interface;
- at least one memory that stores instructions;
- and
- at least one processor that executes the instructions to cause the information processing apparatus to perform operations comprising:
- obtaining an IP address assigned to the network interface;
- transmitting to the server an inquiring request for inquiring about whether the information processing apparatus is open to a global network, the inquiring request including at least the obtained IP address;
- receiving a response to the inquiring request from the server, the received response including information indicating whether the information processing apparatus is open to the global network, the information being determined based on a result of comparison of the obtained IP address included in the inquiring request and an IP address designating a sender of packet data constituting the inquiring request;
- and
- notifying a user of the information processing apparatus, when the response indicates that the information processing apparatus is open to the global network, of a warning that a security level of the information processing apparatus is low.
A method of controlling an information processing apparatus capable of communicating with a server, the information processing apparatus including a network interface, the method comprising:
- an obtaining step of obtaining an IP address assigned to the network interface;
- an inquiry step of transmitting to the server an inquiring request for inquiring about whether the information processing apparatus is open to a global network, the inquiring request including at least the obtained IP address;
- a receiving step of receiving a response to the inquiring request from the server, the received response including information indicating whether the information processing apparatus is open to the global network, the information being determined based on a result of comparison of the obtained IP address included in the inquiring request and an IP address designating a sender of packet data constituting the inquiring request;
- and
- a warning step of notifying a user of the information processing apparatus, when the response indicates that the information processing apparatus is open to the global network, of a warning that a security level of the information processing apparatus is low.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of controlling an information processing apparatus capable of communicating with a server, the information processing apparatus including a network interface, the method of controlling the information processing apparatus comprising:
- an obtaining step of obtaining an IP address assigned to the network interface;
- an inquiry step of transmitting to the server an inquiring request for inquiring about whether the information processing apparatus is open to a global network, the inquiring request including at least the obtained IP address;
- a receiving step of receiving a response to the inquiring request from the server, the received response including information indicating whether the information processing apparatus is open to the global network, the information being determined based on a result of comparison of the obtained IP address included in the inquiring request and an IP address designating a sender of packet data constituting the inquiring request;
- and
- a warning step of notifying a user of the information processing apparatus, when the response indicates that the information processing apparatus is open to the global network, of a warning that a security level of the information processing apparatus is low.
A method of notifying to a user of a warning message relating to a network using an information processing apparatus and a server, comprising:
- the information processing apparatus transmitting to the server an inquiring request for inquiring about whether the information processing apparatus is open to a global network, the inquiring request including at least an IP address assigned to a network interface of the information processing apparatus;
- the server, upon condition that the server receives the transmitted inquiring request, comparing an IP address designating a sender of packet data constituting the inquiring request and the IP address included in the transmitted inquiring request and determining whether the information processing apparatus is open to the global network;
- the server transmitting information indicating whether the information processing apparatus is open to the global network as a response to the transmitted inquiring request, the information being obtained from the result of the determination;
- and
- the information processing apparatus, upon condition that the information processing apparatus receives the response from the server, controlling whether to notify the user of the warning message based on the response.
