基于预防策略的计算机网络防御技术分析

An Analysis of Computer Network Defense Technology Based on Prevention Strategy

传统的网络安全技术对于网络攻击主要采取的是被动防御的手段,而对日益复杂和千变万化的各种入侵事件,这些技术逐渐变得力不从心。文章结合文献研究以及自身的调查,针对计算机网络安全现状进行了深入分析,得出当前计算机网络安全现状不容乐观、存在系统漏洞、用户安全意识不足、反病毒技术不完善等问题。建议加大计算机网络防御技术的研发,包括反病毒技术、主动式动态网络防御技术、基于行为识别技术的网络防御系统等,并在此基础上建立人性化的计算机网络安全机制。

Traditional network security technology mainly adopts passive defense means for network attacks.In the face of increasingly complex and ever-changing intrusion events,these technologies gradually become inadequate.For this reason,this paper combines the literature research and its own investigation,carries on the thorough analysis to the present situation of computer network security,and draws the conclusion that the current situation of computer network security is not optimistic,there are system vulnerabilities,user security awareness is insufficient,anti-virus technology is imperfect and so on.In order to further enhance the computer network,we should strengthen the research and development of computer network defense technology,including anti-virus technology,active dynamic network defense technology,network defense system based on behavior recognition technology,and establish a human-based computer network security mechanism.
