RELAY CONTROL DEVICE, RELAY CONTROL SYSTEM, RELAY CONTROL METHOD, AND RELAY CONTROL PROGRAM

摘要

On the basis of a policy that is information correlating a match condition, which is information distinguishing packets, and communication approval information, which indicates whether or not communication to a destination device is approved for packets corresponding to the match condition, a communication approval assessing means assesses whether or not to approve communication to the destination device for packets corresponding to the match condition from information in packets received by a packet relay device. On the condition that the communication approval assessing means has determined not to approve communication to the destination device for the packets corresponding to the match condition, a rule setting means sets rules, which implement processing for preventing the transfer of the packets to the destination device, in at least the packet relay device that received the packets.
