防火墙技术在计算机网络安全中的应用

计算机网络具有数据通信、信息处理、资源共享等功能与特点，其经常会出现一些网络安全隐患，降低计算机运行的效率。为保证计算机网络安全，需要应用防火墙中的加密技术、安全防护技术、数据修复技术等，以减少外部攻击，降低网络安全隐患；实现数据加密，提升网络数据的安全性；加强计算机网络的访问安全；对日志监控、安全配置进行防护；分析用户的危险行为，提升路由器防护效果。通过应用防火墙技术，可以让计算机网络更加安全，使用效率更高。

Application of Firenall Technology in Computer Network Security

Computer networks have functions and characteristics such as data communication, information processing, and resource sharing, and there are often some cyber security risks, which reduce the efficiency of computer operation. In order to ensure computer cyber security, it is necessary to apply encryption technology, security protection technology, and data repair technology in the firewall to reduce external attacks and reduce cyber security risks, realize data encryption and improve the security of network data, strengthen the access security of computer networks, protect log monitoring and security configuration, analyze the dangerous behavior of users and improve the protection effect of routers. By appl-ying firewall technology, computer networks can be safer and more efficient.
