REALTIME INTRUSION PROTECTING METHOD FOR NETWORK SYSTEM CONNECTED TO WIRE AND WIRELESS INTEGRATED ENVIRONMENT

摘要

PURPOSE: A real time intrusion protecting method in a wire and wireless integration system is provided to increase reliability of security in a wire and wireless integration system and to protect a system from a malicious packet in a wire and wireless integration system. CONSTITUTION: A control unit confirms and registers a wireless IP(Internet Protocol) address and a wire MAC(Medium Access Control) address. The control unit confirms and registers a wireless MAC address of the terminal. The controller registers USIM(Universal Subscriber Identity Module) information of the terminal or PKI(Personal Key Infrastructure) information. The controller determines approval of a terminal which requests network access by confirming wire MAC information, wireless MAC information, and USIM information.
