网络信息与人们的生活息息相关。当前,在科技力量的推动下,不断扩展了云计算技术的运用,并在很大程度上提高了数据的储存空间以及运算能力。同时,实现了网络资源的最大化利用,满足了人们对资源的深层次需求。然而,在云计算网络下,依然存在着网络安全问题。本文首先分析了在云计算环境下,采用网络安全技术的重要性。然后,分析了当前网络环境中存在的风险因素。最后,结合相关的技术经验,提出了在云计算环境下,实现网络安全技术的几个路径。 Internet information and people’s lives are closely related. Currently, with the promotion of science and technology, the use of cloud computing technology has been continuously expanded, and the data storage space and computing power have been greatly improved. At the same time, to maximize the use of network resources to meet the deep-rooted needs of people. However, in the cloud computing network, there are still network security issues. This paper first analyzes the importance of adopting network security technology in a cloud computing environment. Then, it analyzes the risk factors existing in the current network environment. Finally, combined with the relevant technical experience, proposed in the cloud computing environment, the network security technology to achieve several paths.
