Firewall System with Strong Authentication

The fundamental theory,key technology and prevailing solution in the security fields were analyzed.A new firewall architecture was discussed in detail.Compared with traditional firewall,it has markedly advantage in generality,transparency and authentication.Firewall,as a comprehensive security protection system,does not mean a single technology or product.Actually,its functionality is the result of cooperation of all basic security components.Particularly,authentication,as the basis of other security function,has specfic importance.We designed and developed a practical security protection system suitable to deployment on the edge of local campus network,which combined the advanced security characteristic of strong authentication mechanism and general proxy firewall architecture.
