The Deign and Research of the Distributed Firewall
Abstract
With the rapid development of Interent network security issues more and more people''s attention, firewall, network security has been a major product, the border firewall as an effective network security technology, provides an internal network protection, but in the Expansion of the network size and increasing diversity in front of the network technology, lack of border firewall also have become increasingly prominent, it''s difficult to achieve network security and the balance between network performance.
In order to overcome the shortcomings of traditional firewall, and retain its advantages, people put forward the concept of distributed firewall distributed the essential feature of the firewall can be summarized as "the implementation of decentralization strategy on the development, preservation of logs scattered on a security strategy must develop a unified administrator , The strategy must be pushed to the edge of networks that host implementation of the log will be unified collection, centralized management.
This paper first analysis of the current traditional firewall and the role of the existing problems, and then distributed through the firewall configuration, the key advantages of the technology and in-depth research, and distributed firewall technology and research from several more representative Kind of model was compared concluded.
