计算机网络信息安全及其防火墙技术应用

现代计算机在使用时，极易遭受黑客，木马和病毒的攻击，从而引发计算机数据的泄漏问题，这不仅给经济财产带来损失，同时也危及到了社会的进步。因此，要想促进计算机网络安全，就必须借助现代先进科学手段设计好防火墙来强化对外不法信息流的排查和屏蔽，从而确保整个计算机网络能够安全稳定运行。鉴于此，本文主要分析计算机网络信息安全及其防火墙技术应用。

Modern computers in use, vulnerable to hackers, Trojan horse and virus attacks, resulting in the leakage of computer data, which not only brings losses to economic property, but also endangers the progress of society. Therefore, in order to promote the computer network security, we must use modern advanced scientific means to design a good firewall to strengthen the investigation and shielding of external illegal information flow, so as to ensure the safe and stable operation of the entire computer network. In view of this, this paper mainly analyzes the computer network information security and the application of firewall technology.
