Abstract:
It is an object of the present invention to achieve improvement of security by a whitelist function and improvement of network reliability by a network redundancy function at the same time. A packet relay device  100  includes packet reception units  200,  a packet transfer unit  300,  a S/W control unit  400,  packet transmission units  500,  and an input/output interface  600  and automatically generates a whitelist including an allowed communication rule. It is possible to select whether to perform communication control using the whitelist or to carry out data communication without using the whitelist for each data reception unit  200  that receives data.

Claim (Index 10):
A communication method comprising:\n setting in advance a first reception unit having a port connected to a redundant network or a ring port or a port having a possibility of occurrence of route switching at the time of failure to be excluded from a target of generation and control of a whitelist which is a list of communication data permitted to be transferred; setting in advance a second reception unit having a port connected to another device or an edge port or a port having no probability of occurrence of route switching at the time of failure as a target of generation and control of the whitelist; transferring communication data to a transfer destination defined in advance when it is determined that the communication data has been received via the first reception unit, in a case where a communication device is set in advance to a whitelist generation state; and generating and storing the whitelist based on communication data that has been received and transferring the communication data to a transfer destination defined in advance when it is determined that the communication data has been received via the second reception unit, in a case where the communication device is set in advance to the whitelist generation state.
