1. Students:Gilad Goldman Lior Kamran Supervisor:Mony Orbach Network Sniffer

2. To offload the task of packet sniffing and filtering from the CPU by using a hardware filter In essence: build a hardware firewall Test packets according to specific header fields: Protocol (ICMP,TCP, ARP...) Source/destination address (IP) Source/destination ports (TCP) Header flags (SYN,ACK…) Transmit test results back to the kernel Abstract
