the 1st European NetFPGA Developers Workshop 1. Introduction NIDS A firewall is not the ultimate solution for network security. ※ Total reliance on the firewall tool may provide a false sense of security. The firewall will not work alone (no matter how it is designed or implemented) as it is not a panacea. ※ It is inconvenient for the firewall because most information about attacks of the firewall depends on the administrators.

the 1st European NetFPGA Developers Workshop 2. Architecture Most parts of this protection system are designed and implemented in hardware to be faster and more secure. For instance, on the one hand, packet filtering in hardware, immunity from ARP attacks in hardware, monitoring and transmitting with hardware acceleration are designed and implemented on the NetFPGA to protect the subnet from network attacks. On the other hand, AES and DES encryption modules in hardware, immunity from the USB virus and Trojan horse by physical isolation are designed and implemented on the DE2 board to protect terminal security effectively.
