摘 要：计算机网络带来了无穷的资源， 但网络安全问题也显得尤为重要。文章重点介绍了局域网的安全控制与病毒防治的一些策略。本文针对局域网的信息安全及防火墙安全技术的分类及其主要技术特征，如网络应用安全威胁分析主要体现在于网络上有众多的欺骗性软件，没有独立的服务器及用户的安全意识差等方面。对于如何去控制安全及病毒防治则有一些具体的策略及实例。安全控制主要是对于人员的网络安全培训及网络入侵检测技术、属性安全控制等。病毒防治需要定制针对性的防毒策略，如增加安全意识，挑选杀毒软件及安装操作系统补丁等。网络空间中也有各种各样的隐患。为了防止病毒侵入局域网，而设计了防毒软件、防火墙、入侵监测技术等方法来预防网络病毒。因此我们必须时刻关注着计算机网络安全建设也是很重要的。

abstract：Computer network brings infinite resources, but also the problem of network security becomes especially important. This paper mainly introduces LAN security control and virus prevention some strategies. Based on the information security and firewall LAN security technology and the classification of the main technical characteristics, such as network application security threat analysis mainly embodies in network with numerous deceptive software, no independent servers and users of poor safety awareness. For how to control the security and virus prevention are some concrete strategies and examples. Safety control is mainly to personnel network safety training and network intrusion detection technology, attribute safety control etc. Virus prevention need to customize pertinence of antivirus strategies, such as increasing safety consciousness, select the antivirus software and installation operating system patch, etc. Network space also has a variety of hidden trouble. In order to prevent virus invades LAN, and design the anti-virus software, firewalls, intrusion detection technology in ways such as prevention network virus. So we have to focus on the computer network security construction also is very important.
Keywords：Lan ； information security ； virus prevention
