NETWORK INTERFACE CARD HAVING DENIAL OF SERVICE ATTACK AND DISTRIBUTED DENIAL OF SERVICE ATTACK FUNCTIONS AND A METHOD FOR INTERCEPTING DENIAL OF SERVICE ATTACK AND DISTRIBUTED DENIAL OF SERVICE ATTACK BY USING THE NETWORK INTERFACE CARD, PARTICULARLY CONCERNED WITH REDUCING AN AMOUNT OF TRAFFIC WITHOUT GIVING A LOAD TO A COMPUTER SYSTEM

摘要

PURPOSE: A network interface card having DoS(Denial of Service) attack and DDoS(Distributed Denial of Service) attack functions and a method for intercepting DoS and DDoS attacks by using the network interface card are provided to intercept the DoS and DDoS attacks incoming and outgoing outside from a network interface card level, thereby reducing an amount of traffic. CONSTITUTION: A packet processor(33) comprises as follows. A program memory(36) preserves an operating program and attack detecting/preventing programs. An RAM(34) loads various programs from the program memory(36), and stores data. A data processor(35) is mounted with an RTOS(Real Time Operating System) to control the program memory(36) and the RAM(34), and processes the data according to the programs to sense and intercept attacks.
