Optimization design and implementation of gateway based on firewall for access control
YaChao Zhu · 2016
Considering that the traditional gateway can't meet the requirements of the increasingly strict network security management, here we propose a design of security gateway based on firewall technology. We realize the real-time, dynamic and fine-grained control of the internal and external network of the gateway. This article introduces a method for gateway to be built, and it's based on the firewall in Linux system. I use both the rule priority and heap sort method to optimize the efficiency of the gateway. It can be proved that the gateway based on heap sort and rule priority evaluation method can effectively reduce the time to solve the exception rule and improve the efficiency of abnormal rules.
