A packet processing system and a packet processing method are disclosed. The system comprises: a network interface card for receiving at least one packet from an external network and transmitting the received packet to a host; and the host for checking the packet received from the network interface card according to a security policy and transmitting the checking result to the network interface card. The network interface card may process the packet by transmitting the packet to an internal network or blocking the packet according the checking result received from the host. In other words, the present invention transmits or blocks the packet according to a series of bit flag type checking results indicating the transmission or the blocking of the at least one packet which the network interface card has received from the host, thereby may minimize a resource of a central processing unit in the host caused by functions of checking and blocking the packet, and furthermore may enhance the overall resource efficiency of the packet processing system.
