Improved Design and Implement of Firewall System
This article focus on analyzing and solving the hidden security problems of firewall itself . As a result, it gives a practical solution: the firewall immune system, which secures the firewall system by the Integrity-inspecting Module, and the Audit and Analysis Module. Firewall is one of the main network security products. Its purpose is to construct a relatively safe subnet environment under the hostile network so as to prevent the unpredictable and hidden damaging intrusion. Firewall provides the information security service for a network and functions as the network and information security infrastructure. In order to ensure the network security, the firewall as much as possible shields the internal network detail, the structure and operating conditions by monitoring, restricting and changing the data stream across it. Firewall consists of hardware platform, basic operating system and functional software1. Apart from the different performances of the firewall products present nowadays, firewall is essentially a software no matter it is a software firewall or a hardware firewall. However, if the firewall isnt immune to assaults or cant prevent the intruders from entering the network, the possible aftermath is a disaster, no mater the firewall functional software is installed on a common personal computer or is preinstalled together with hardware in a pretty box.
