Abstract

Packet filtering technique is widely-used in host firewalls and it often needs setting filter rules by user. The paper presents an improved method of packet filtering. In the method, packets are related with userís network application operations and the processes operated by users can transfer and receive network packets. The result shows that the method is more intelligent to defend certain kind of Trojan horses. It could reduce userís operations of setting filter rules† in considerable extent and Trojan horse deformation is useless in theory. The description in the paper would be valuable for constructing more intelligent defending system.
