摘 要 计算机网络的发展和技术的提高给网络安全带来了很大的冲击,Internet的安全成了新信息安全的热点针对计算机网络系统存在的安全性和可靠性问题本文从的及定义、网络攻击的一般及其提出一些见解，并且进行了总结，就当前网络上普遍的提出了网络安全设计的重要理念,以使用户在计算机网络方面增强安全防范意识 Abstract The development of computer networks and technologies to enhance network security is a big blow, Internet security has become a new hotspot of information security. Network security is the security of computer information systems in an important aspect. Like opening of the Pandoras Box, the computer systems of the Internet, greatly expanded information resources sharing space at the same time, will be its own exposure to the more malicious attacks under. How to ensure that the network of information storage, processing and transmission of information security security, is the so-called computer network security. Information security is to prevent information from the property have been deliberately or accidentally leaked authorized illegal, altered, damage or illegal information system identification, control; ensure confidentiality, integrity, availability, controllable. Information security, including the safety of the operating system, database security, network security, virus protection, access control, encryption and identification of seven areas. Design of a network security system, which must be done to effectively prevent the network all of the attacks, guarantee the safety of the system, and also have a higher cost-effectiveness, operational simplicity, and transparent to the user interface and friendly. Computer network system of security and reliability problems, the paper from the network security and the proposed definition, Network security risk analysis, network attacks generally means Enterprise LAN security design principles and disposition program some insights, and it was summed up, on the current network-wide security threats the network security of the important design concepts and security management norms and against common network fault analysis and solution to enable enterpris
