互联网技术应用范围的不断扩大,人们逐渐认识到保护网络安全对推动经济发展、维护社会稳定、保障公民合法利益等方面的重要性,并尝试通过提升物理安全和通信安全、进行控制访问和信息加密、优化系统计划和管理等手段提升网络安全,防火墙技术是现阶段应用较为广泛且效果较突出的网络安全技术手段之一。本文针对LINUX环境下的防火墙网络安全设计与实现问题展开研究,提升防火强的透明性、适用性、可操作性、经济性和安全性、实用性,为提升网络安全提供参考。
With the continuous expansion of the application of Internet technology, people are gradually realizing the importance of protecting network security in promoting economic development, maintaining social stability and safeguarding the legitimate interests of citizens. Attempts to control access and encrypt information by improving physical security and communication security , Optimizing system planning and management to enhance network security. Firewall technology is one of the most widely used and effective network security technologies at this stage. In this paper, research on the design and implementation of firewall network security in LINUX environment is carried out to improve the transparency, applicability, operability, economy and security of the fire prevention, and practicality, to provide reference for improving network security.
