计算机病毒解析与防范技术研究

计算机病毒解析与防范技术研究摘 要伴随着计算机系统的不断发展，目前计算机病毒已成为系统以及网络安全的巨大威胁。因此要对计算机病毒常见类型以及基础常识进行把握，在这样的前提下如果遭遇病毒不会变的束手无策。基于此，本文对计算机病毒的定义、传播方式以及受到感染之后的现象进行详细分析，并分析了计算机病毒的传播方式，主要包括基于网络的病毒传播模式、计算机常见病毒、几个经典的计算机病毒传播模型，进一步研究了计算机病毒防御方法，包括基于主机的检测方案、基于网络的检测策略、创建一套完善的病毒防护机制、对防治技术进行不断完善，同时对病毒检测手段进行升级，最后对病毒防范措施进行详细分析，除了漏洞扫描以及防火墙等技术之外，还包括反病毒、计算机病毒免疫技术，以便最大限度地减少计算机病毒造成的危害。关键词：计算机病毒；计算机病毒传播途径；预防计算机病毒I AbstractWith the continuous development of computer systems, computer viruses have become a great threat to system and network security. Therefore, we should grasp the common types of computer viruses and basic common sense, under such a premise, if encounter viruses will not change at a loss. Based on this, this paper makes a detailed analysis of the definition, mode of transmission and the phenomena after infection of computer viruses, and analyses the mode of transmission of computer viruses, mainly including network-based virus transmission mode, common computer viruses, several classical computer virus transmission models, and further studies the methods of computer virus defense, including host-based detection. Measuring scheme, network-based detection strategy, establishing a set of perfect virus protection mechanism, improving prevention and control technology, and upgrading virus detection means. Finally, the virus prevention measures are analyzed in detail. In addition to vulnerability scanning and firewall technologies, anti-virus and computer virus immune technologies are also...
