Abstract :Content or string matching is the core process of deep package inspection and pattern recognition used by the Network Intrusion Detection and Prevention Systems insert ignore into journalissuearticles values(NIDPS);. Although there are many sophisticated algorithms in software it is an exhaustive process and still beneath the requirements of the high-speed network traffic. In this paper is presented a flexible hardware solution i.e. microprocessor able to recognize known attack patterns and its variants to overcome the software NIDPS outage caused by 1 Gbps insert ignore into journalissuearticles values(and beyond); throughputs. Since many modified network attacks use so called evasion techniques the presented approach is an 8-bit dedicated microprocessor for exact and approximate string matching. To construct the design itself and to perform the simulation environment the Xilinx ISE Web Pack simulator is used.
