随着现代计算机网络技术的不断发展,计算机网络在人们的日常生活中发挥越来越重要的作用,伴随着计算机网络技术的逐步发展和完善,计算机网络攻击的手段也逐渐多样化和复杂化,因此计算机网络的信息安全也开始越来越受到威胁,计算机网络信息防护已经变得越来越重要。现在常见的网络攻击有网络监听、放置木马程序、系统安全漏洞、拒绝服务攻击等,这些都严重危害了计算机网络的安全。本文将分析和研究目前几种常见的网络攻击手段,并针对这些攻击手段提出了相应的网络安全防范策略,以此来增强网络的安全性。 With the continuous development of modern computer network technology, computer network plays an increasingly important role in people’s daily life. Along with the gradual development and improvement of computer network technology, the means of computer network attack gradually diversified and complicated, Therefore, the information security of computer network is also beginning to be more and more threatened. The protection of computer network information has become more and more important. Now common network attacks have network monitoring, placing Trojans, system security vulnerabilities, denial of service attacks, which are seriously endangering the safety of computer networks. This article will analyze and study several common means of network attacks, and propose corresponding cybersecurity prevention strategies for these attacks to enhance network security.
