局域网环境下的网络安全技术研究

在信息时代的今天，局域网既实现了信息数据的快速共享，也提升了信息传播的效率。网络所具备共享性、复杂性、开放性等特征，也使得计算机网络安全难以得到有效保障，进而衍生出很多网络安全问题。基于此，本文分析了在局域网环境下的网络安全技术措施，从而确保计算机网络信息的保密性、安全性与完整性。

Network security technology based on LAN environment

In today's information age, LAN not only realizes the rapid sharing of information and data, but also strengthens the dissemination and sharing of information efficiency. However, due to the openness of the network, many viruses have a serious impact on the security of LAN information. Therefore, people realize the key of the application of computer network security technology,how to improve the security of network information, this is the focus of the topic. Based on this, this paper analyzes the effective application of network security technology in LAN environment, which is of great significance to improve the security and reliability of network technology in china.
