Research On The Distributed Firewall And It's Rule Executer

The development and popularization of the network technology make the network security more and more receives attention by all levels of users. The firewall is one kind of essential safety mechanism, but the traditional edge firewall only can peripheral provide the protection to the network, but is helpless to the network interior attack. Distributed Firewall is one kind of main engine in the keeping -like safety system, protects the network essential point server the data and the workstation exempts the illegal invasion destruction. It can resolve several problems that traditional ones can't, and offer overall protection to the users. Make the system of fire wall more systematized. It is the developing direction of the system of fire wall in the future.Firstly this article obtained from the traditional firewall correlation technology and the characteristic, has analyzed the traditional firewall function and the existence question, thus has drawn out the distributed firewall concept, has analyzed its main system structure, the characteristic and the main superiority, and had the representative to the distributed firewall related technology as well as the research area several kind of models to carry on the comparison summary.Next, through to the firewall strategy definition, the implementation and the distribution mechanism research, has carried on the discussion to the distributional firewall strategy management, and emphatically its strategy execution function, the characteristic and the correlation technology have made the system analysis.Once more, through to the strategy execution implementation plan comparison, as well as its structure, the processing flow and the stable analysis, produced in the system the package to filter with the monitoring module software realization.Finally summarized the full text and proposed some are worth the question which studies.
