硬件防火墙在网络安全中的应用

随着计算机技术的飞速发展,计算机在全球各个领域得到了广泛的普及和应用,使得信息的传递在全球范围内进行,单台计算机已经失去了自身的作用,网络成为了人们生活中必不可少的部分.但是在网络的发展为人类创造巨大财富的同时,网络的安全问题也越来越成为影响计算机网络发展的重大问题,如何使网络安全得到保障,如何使数据资料免受黑客的攻击,防火墙的出现从根本上解决了这些问题.防火墙可以实现外网与内网之间的安全隔离,同时也可以实现内网内部计算机之间的安全访问,从而彻底解决了计算机网络的数据安全问题.

Hardware Firewalls in the Application of Network Security

Along with the rapid development of computer technology, computer in the world in various fields have been widely applicated. Making the transfer of information within the global computers is a very important thing.The solated computer have lost their role when network appears. However, in the development of networks ,when mankind have created enormous wealth, network security issues also affect computer networks increasingly,it becomes the major development problem.How to solve the network security is a very hard problem.How to protect the coputer and how to make the data safe from hackers, the emergence of firewall fundamentally solve these problems. Firewalls have achieved the progress by founing a wall between the internal network and outside network, it also have achieved the progress of accessing data within the internal computer network and these measure will solve the problem of data security.
