1. Company Profile

ZTE is China's largest listed telecommunications equipment manufacturing companies, the Chinese government focus on support of one of the 520 key enterprises. Founded in 1985. In 1997, ZTE A shares in Shenzhen Stock Exchange. In 2002 sales reached 11 billion yuan. ZTE is China's Torch Program Key High-tech enterprises, technological innovation pilot enterprises and 863 high-tech achievements into a base commitment to China's third generation mobile communications research and development and other key research projects, investment in research funding each year accounted for more than 10% of total sales . ZTE to implement people-oriented human resources strategy, a set of introduction, training, use, incentive mechanism for talent. 13,000 employees, Ph.D., postdoctoral more than 300 people, 4,000 master's, bachelor degree or above accounted for 75% of the total number of employees.

As a network, our unit of more than 100 computers are under my control, to distinguish between different users, assign access to more detailed, we started with a Shezhiguding IP approach, instead of automatic 获取 IP address. In addition, because the business needs, the company also has a part to be connected to the Internet. This would set up two subnets, for example: we set within the network 192.168.0.1 network segment, we can even set outside the network 192.168.1.1 network segment. However, the actual use of the process, there has been a cause headaches, a user to modify the IP address of the Internet without permission, resulting in network conflicts. I have no peace in this network and therefore, he was often called the computer can not access, please Zan handle it.

Campus network is a hierarchical topology, so network security is also required to adopt protective measures at different levels of topology. That is a complete network, network information security solutions should cover all levels of network and security management with the combination.

Botnets (Botnet) is more than malicious code infection, control of the computer connected to the Internet. Botnet is becoming an increasingly serious threat, but as long as we deal with it with a good six swords, botnets would be difficult to cause serious hazards.

Almost all business focus for the network security level had been increased, have purchase a firewall from the Internet and other devices want to block unsafe factors. However, Intranet internal attacks and the invasion is still rampant. Proved to insecurity within the company even more horrible than the external damage.

In 2006, we see people around network security is gradually maturing, but also to see the network security market, the trend to diversification, and security vendors homogenization phenomenon gradually horizon. Can be said that we drag the body, such as in looking forward to greeting the Windows Vista, Internet Explorer 7 of the latest version of the software, although they were marked with the brand of security, but there are many loopholes in the shortest time being disclosed . The creators of viruses and Trojan positive organized team development, personal tracker sites increase, leading to intrusion of civilians ... ... The end of regret, all I feel is not the end of 2006, a sense of the year.

In most modern networks, links and nodes in the star network (each node connected directly to the central switch, hub, or server) or the bus configuration (each node connected to the central exchange of components with a total connected trunk) connected with each other. Both configurations are well understood, and inexpensive, reliable, but the installation of any of a fault will isolate the node and its out of the network.

Currently the field of network security to face serious problems. On the one hand today's society by John of the network increasing network intrusion and attacks the other hand the number of incidents has risen sharply. These two aspects of interaction, the former allows the network architecture, protocol and applications become more complex, but also lead to social security problems on the network can gradually reduce the degree of tolerance. Dry some of the industry, network failure may no longer be a small accident, but a disaster; to protect network security, a variety of network intrusion detection and prevention technology came into being. This paper present a variety of network intrusion detection and prevention technology, a comprehensive description, pointed out their strengths and weaknesses, and to explore and study a network intrusion detection defense technology development trend of the future. This article is as follows: the first part of this article will mainly discuss the current network intrusion detection Intrusion Detection Systems (IDS) and its key technology. The third part of the paper will discuss the development trend of intrusion prevention technology: Based on the time line of intrusion defense system. The third part is a summary of this article.

1. Security Requirements

SME users of LAN network structure in general is not very complicated, not too much the number of hosts, servers, services provided by relatively few.
