The present invention relates to a multiple host-based network security device and a method for processing packet data using the network security device. The multiple host-based network security device of the present invention comprises at least two individual hosts in a single host system. Each of the individual hosts comprises individual resources such as a central processing unit (CPU) and a memory, and performs a different task in a single host system. The network security device comprises a packet policy module for providing a packet classification policy such that packet data are sent properly to the individual hosts, and a packet processing unit for sending the packet data to a relevant individual host according to the packet classification policy and providing services or blocking the packet data in accordance with packet checking results performed in the individual hosts. Thus, the data processing performance can be improved and the packet data can be stably checked.
