In this thesis,we propose architecture of cooperative firewall system,which is based on the distributed firewall,and the concepts of defense in cooperative defense,and explain the operating procedures of cooperative firewall in the system architecture.

This paper focused on the design and realization of a Linux-based software bridge-firewall system in the mobile storage devices, which is simple, flexible, efficient and can be rapid deployed.

Aimed at hardware accelerated universal firewall,this paper proposes a new packet processing flow which improves the system\'s performance sufficiently and its complete functions are guaranteed.

Design and Implementation of EFW Based on Linux;

In view of the problems existing in network security systems available, a self immune distributed micro firewall architecture is presented.
