Overview:
The software firewall is a software product based on a single core CPU to accomplish various security functions. To enhance stability, the hardware used is usually a general-purposed CPU on an industrial-strength motherboard, with a standard PCI network card as the external network interface. In the software firewall, data are transmitted to the CPU via the PCI network card for processing, including performing various security services and related protocols. When the CPU is done, the data are then sent back to the network card via the PCI bus.
