随着计算机网络的快速发展,人们生活的方方面面都和网络有联系,网络为人们提供便利的同时也存在一些网络安全问题,例如网络诈骗,窃取网络数据等,因此网络安全问题越来越被人们所重视。网络安全的基础是网络安全协议,这项协议是人们通过对计算机网络通信进行大量的研究后得出的,它能够科学正确地保证网络通信安全,避免网络数据丢失、损坏或泄露。本文阐述了网络安全协议的主要内容,探讨了在计算机通信技术中,网络安全协议所起到的作用,希望对相关从业人员有所启发。 With the rapid development of computer network, people have all aspects of life and the network are linked, the network for people to provide convenience but also there are some network security issues, such as network fraud, theft of network data, network security issues more and more people Attention. Network security is based on the network security protocol. This protocol is based on a large amount of researches on computer network communications. It scientifically and correctly guarantees the network communication security and avoids network data loss, damage or leakage. This paper describes the main contents of the network security protocol, explores the role played by the network security protocol in the computer communication technology, and hopes to inspire the relevant practitioners.
