现如今,互联网技术正在得到十分快速的发展,而互联网技术的应用,也使得人们的日常生活、工作的方式得到了很大的改善,使得人们得到了很大的便利。但是,信息化虽然一方面给人们带来了极大的便利,另一方面也使得人们需要面临网络带来的安全威胁,例如数据盗窃、黑客侵袭、病毒发布等,都使得我们无时无刻不面临着从网络当中出现的安全问题。虽然目前我们对各种防火墙、杀毒软件等复杂的软件技术进行了广泛的使用,但不管是在发展中国家还是发达国家当中,黑客都在呈现出愈加猖狂的趋势,与此同时,还有一些黑客网站使得黑客可以更好的对技术进行学习,并更轻易的对攻击工具进行获取。这样的情况,使得互联网当中的安全性一再降低。针对网络当中不断出现的安全威胁,如何才能够使得信息的安全性得到有效的保证已经成为了十分重要的问题,本文针对威胁网络安全的一些问题,有针对性的提出对网络安全进行防护的策略。 Nowadays, Internet technology is getting very rapid development, and the application of Internet technology also makes people’s daily life and work methods have been greatly improved, making people have a great convenience. However, while informatization brings great convenience to people on the one hand, on the other hand, people also need to face the security threats posed by the network, such as data theft, hacker attacks, virus release, etc., all the time make us face all the time Security issues that arise from the internet. Although we are currently using a wide range of complex software technologies such as firewalls and anti-virus software, hackers are showing increasingly furious trends both in developing and developed countries, while others Hackers make hackers better at learning about technology and making it easier to get access to attack tools. This situation makes the security of the Internet has repeatedly reduced. In view of the constant emergence of the network security threats, how to make the information security is an effective guarantee has become a very important issue. In this paper, some of the problems that threaten the network security, targeted to put forward the strategy of network security protection .
