1 Analysis of Network Security Technology
1.1 Overview of the 21st century will be the world's Computers are connected together through the Internet, information security, meaning a fundamental change will occur. It becomes not only from the general defense against a very ordinary, but also from a areas of expertise into everywhere. a country's information security system is actually composed of national regulations and policies, and Technology and market development platform. of information defense system in the building, they should focus on developing their own unique security products To really solve our problem of network security, the final solution is national security through the development of industries and of the overall improvement of network security Technology. network security products have the following major characteristics: first, network security, security strategy and Technology from diversity, if we adopt a unified strategy for Technology and also unsafe, and second, the network security mechanisms and technologies constantly changing, and the third, as the network extends in all aspects of society, safe means of access to the network more and more, so network security is a very complicated system. To this end to establish a network security system with Chinese characteristics, needs the support of national policies and legislation and joint Research and development group. safety and security as anti-conflict two aspects of the constantly upward climb, so the security Industry in the future as new technology is a constantly developing Industry.

1.2 is a firewall network firewall technology to strengthen the network between the access control to prevent the external network users to illegally enter the internal network via the external network, access to internal network resources, protect the internal network operating environment and the special networking equipment. Its two one or more networks, such as data packets transmitted between the links according to a certain way to implement security policy check to determine whether the communication between the networks are allowed, and monitor the network running. Although the firewall is protecting the network against hacker attacks effective means, but there are obviously inadequate: not protect against other ways than through a firewall attacks, not prevent change from within the section and not attentive to the threat posed by users, we can not completely prevent transmission have been infected with the virus software or files, and can not guard against data driven attacks.

1.3 The choice of firewall selection criteria for a lot of firewall, but the most important is that here the following:
1.3.1 The total cost of ownership as the network firewall security barrier, the total cost of ownership (TCO should not exceed the protected network system may suffer the worst damage costs. Of course, the key sector, and its negative impact consequential damages should also be taken into account. if only for a rough estimate, non-critical sectors of the firewall network system acquisition cost should not exceed the total cost of construction, the key sectors should be a different matter.

1.3.2 The firewall itself is safe as an information system security, firewall itself should ensure safety, do not give outsiders an opportunity to exploit. Usually, the security of the firewall from two aspects: First, the design of the firewall itself is reasonable. The second is used improperly.

1.3.3 Management and training management and training is to evaluate the quality of the important aspects of a firewall. Staff training and daily maintenance costs typically account for a large proportion of the TCO. An outstanding supplier of security products to its customers to provide a good training and after-sales service.

1.3.4 Scalability with network expansion and the increase in network applications, the network will dramatically increase the risk of cost, when they need to increase with improved security firewall products. Such as early acquisition of the firewall is not scalable, or expansion of high costs, this is a waste of investment. a good product should be flexible enough space left to the user, in the case of security level is not high, it can only buy the basic system, and as requirements increase, users there is still room to further increase the options. This can not only protect the user's investment, to improve the firewall product manufacturers, has expanded its product coverage.

1.3.5 firewall security firewall firewall is the most difficult to assess the safety aspects of performance. This is the same as the security of the firewall itself, ordinary users often can not judge. So that the user in the choice of a firewall product, market share should try to choose while the larger certification testing by the authority of the product.

Network security is to ensure the integrity of data and information to eliminate the security threat is the entire system for each Computer application system must be taken into account. Computer systems and information security, including data integrity and system security are two aspects: data integrity of information that data is not damaged or missing, with full reliability and accuracy, system security refers to the prevention of theft and intentional damage to data, Computer systems typically use security products and measures to ensure that the data from threats.

2.1 Data integrity and system security analysis of the impact of factors
2.1.1 Data integrity threats mankind itself: the main action was accidental, the lack of experience, intentional destruction, natural disaster areas: including earthquake, flood, fire, electromagnetic, logic problems: including application software errors, file corruption, data exchange errors, operating system error, capacity errors, such as improper user needs, hardware failures: the major systems that constitute the various components of hardware, such as hard drives, chips, motherboards, storage media, power supply, I / O controller failure, the network work: network failure, including connectivity problems (such as a bridge or router congestion caused by the buffer is not big enough, the network interface card and driver problems and radiation problems.

2.1.2 System Safety factors affect the physical device: refers to the theft of equipment, a direct reading device, espionage and other information to direct mode on the impact of cable connections include: dial-up access, the connection or connection (such as magnetic field of eavesdropping to steal important information, identification of: including the password is compromised, the encryption algorithm ill, are free to set passwords and other vulnerability factors, or programming of the virus: the virus attacks has become the greatest threat to Computer systems. In addition, some programming technical personnel for a particular purpose, and deliberately write a code hidden in the system, pose a threat to the system.

2.2 office automation network system's security design because many factors have contributed to the threat of data integrity and security threats, therefore, office automation system must build a comprehensive strategy and security measures to protect the security of the whole system: the establishment of a set of security measures , and strengthened external security, to strengthen internal security.

3 Conclusion
Network Security Technology in the 21st century will be the key to the development of information network technology into the 21st century information society, the information in this important strategic resources for social development needs of network security technology of effective protection, in order to form the driving force of social development. In我国 information network security technology Research and product development is still in its infancy, there is still a lot of work we need to Research, development and exploration in order to get out of development with Chinese characteristics, road, catch up with or than the developed countries level, as to ensure the security of information networks and promote the rapid development of China's national economy.
