Device, method and system of handling access control

A method of handling an access control for a management device, comprising:

• receiving a first information and performing a first determination on whether an administrator device is correct according to the first information;
• performing a second determination on whether the administrator device comprises an access qualification for a remote device, when the first determination is positive and when receiving a first request message for accessing the remote device;
• performing a third determination on whether the administrator device comprises an access right of the remote device, when the first determination is positive;
• transmitting a second information of the remote device to the administrator device, when the third determination is positive, wherein the second information comprises an identity of the remote device;
• transmitting a second request message for establishing a connection with a network device to the remote device, when the second determination is positive and when determining to establish the connection with the network device;
• and
• transmitting a third request message for configuring a port forwarding to the network device, when the second determination is positive.

A system of handling an access control, comprising:

• a management device and a network device, wherein the management device comprises:
• a first authentication module, for receiving a first information and performing a first determination on whether an administrator device is correct according to the first information;
• an authorization module, coupled to the first authentication module, for performing the following operations:
• performing a second determination on whether the administrator device comprises an access qualification for a remote device, when the first determination is positive and when receiving a first request message for accessing the remote device;
• performing a third determination on whether the administrator device comprises an access right of the remote device, when the first determination is positive;
• and
• transmitting a second information of the remote device to the administrator device, when the third determination is positive, wherein the second information comprises an identity of the remote device;
• a communication module, coupled to the authorization module, for transmitting a second request message for establishing a connection with the network device to the remote device, when the second determination is positive and when determining to establish the connection with the network device;
• and
• an integration module, coupled to the authorization module, for transmitting a third request message for configuring a port forwarding to the network device, when the second determination is positive;
• and
• the network device comprises:
• a connection module, for receiving a fourth request message for establishing a second connection from the remote device, and establishing the second connection with the remote device according to the fourth request message;
• an integration module, coupled to the connection module, for receiving the third request message for configuring the port forwarding to the remote device from the management device, and establishing the port forwarding and transmitting a first path to the management device according to the third request message, in response to the third request message;
• and
• a network service module, coupled to the integration module, for receiving a fifth request message for accessing the remote device from the administrator device, and performing an application level service with the remote device according to the fifth request message.
