Design and Research of Firewall System of Communication Department Based on Network Information Technology

In the past, the structure of traditional firewalls was similar to that of checkpoints, and the design structure was relatively simple. At the same time, it is also convenient for subsequent maintenance. As an isolation technology, it can be accessed by people with consistent identity information. But for some relatively high-level data information, using traditional firewalls, foreign intruders can easily obtain relevant information. This article chooses to use the working mechanism of network information technology, and then analyzes the hardware structure of the firewall based on the IPX2400 processor. Finally, a preliminary design of a firewall system for the communications department based on the IPX2400 processor is implemented, and its packet filtering function is realized.
