Disclosed is an apparatus for displaying the state of a network to enable a user to intuitively recognize a network security situation. The disclosed apparatus for displaying the state of a network includes: a security event collecting unit that collects security events from the outside; an IP address converting unit that converts a source IP address and a destination IP address in characteristic data of the collected security events into geographic information on the basis of information stored in a geographic information database; and a network state display unit that displays the flow of security events for each protocol between a source and a destination as an image including a globe shape, on the basis of the characteristic data and the geographic information transmitted from the IP address converting unit.

Apparatus and method for visualizing network state by using geographic information

The invention relates to a P2P traffic management apparatus and method. A P2P flow agent monitors an executed application program to extract a P2P application program, adds application identifiers to packets generated by the application program according to a set policy, and transmits the packets. In this case, a P2P security gateway monitors the inflowing packets from the P2P flow agent to extract packets having the application identifiers, uses the extracted application identifiers to inquire and acquire a related policy, and controls the packets according to the acquired policy.

Apparatus and method for managing P2P traffic

An authentication gateway apparatus for accessing a ubiquitous service includes: an authentication server of a service provider that receives an authentication data request message from a portable apparatus, and provides an authentication token; a first authentication device of the portable apparatus that transmits the authentication data request message to the authentication server, receives and stores an authentication token from the authentication server, and is used as a representative authentication device; and second authentication devices of ubiquitous apparatuses that are connected to the first authentication device of the portable apparatus by a wireless communication system, and have individual unique values.
