APPARATUS AND METHOD FOR MONITORING PACKETS, AND APPARATUS AND METHOD FOR MANAGING ALTERED DATA

摘要

As a packet-monitoring apparatus for monitoring packets jointly in connection with an altered data managing apparatus, a packet-monitoring apparatus includes a communication module unit that handles data communication via a communication network. Also included is a monitoring control unit that determines whether or not packet data received through the communication module unit has been altered on the basis of a preset protocol format, checks whether or not a related pattern corresponding to packet alteration information showing an altered portion of the packet data has been detected in an inbound packet and an outbound packet, and transmits resultant distribution terminal information to the altered data-managing apparatus.
