In modern society, information system has become the main driving force for the development of all walks of life, because the appearance of information system can bring more convenient conditions for people's life and development. For the existing enterprises in China, the entry of information technology can improve the existing work efficiency and people's work rhythm. In many cases, people can communicate with the outside world through computer network system, which saves people's communication time to a great extent. In the information age, enterprises must constantly improve their competitiveness if they want to achieve the strategic goal of sustainable development. First, actively introduce senior technical talents to lay a solid foundation for the development of enterprises [1].
1 development direction of modern enterprises
Judging from the current situation, Chinese enterprises are developing in a diversified way. Compared with the traditional relational system, today's information management system occupies a very important advantage. Computers play an important role in enterprises, laying a solid foundation for people's information management and network construction. Moreover, modern enterprises often regard computer information management system as the key content of development, and both enterprise management and computer network construction attach great importance to the application of science and technology, which is very different from traditional enterprise management. Therefore, the author believes that in the future development, the development of enterprises will better realize the trend of diversification and diversification.
2 the relationship between enterprise modernization management and computer network construction
2. 1 Modern network construction will promote enterprise development.
Modern network construction will promote the economic development and construction of enterprises in China. In the 2 1 century when internet technology is very developed, how to use modern network technology has become the main content of people's concern. Only by better realizing the construction and development of informatization can we keep pace with the times. In the development of traditional enterprises in China, people tend to pay attention to the economic benefits of enterprises, but not to the management methods and methods of enterprises. But now many domestic enterprises have realized and changed their management methods. With the rapid development of information technology in the 265,438+0 century, the Internet has developed rapidly. Only by learning to use modern network technology for enterprise management and planning can we better realize the sustainable development of enterprises [2].
2.2 Modern network construction can realize resource sharing.
The use of modern network construction can also realize the enjoyment of resources, which is not available in traditional enterprise management. In the modern 2 1 century, people can use the modern management system to inject their own management methods into network construction, and they can consult them once they need to use them. In general, an enterprise will involve multiple departments. In order to make the relationship between departments very close, we should communicate regularly. In the modern 2 1 century, only by strengthening the communication between various departments within the enterprise can the long-term development of the enterprise be better realized.
Internet technology can enable enterprises to share information resources and provide more protection for people's work and development. The biggest advantage of computer network is that it can share information resources. With this advantage, we can focus on the application of the network in practical work. Compared with the traditional computer network technology, modern technology has great advantages, both the response speed and the error rate exceed the traditional enterprise management mechanism, which also lays a solid foundation for the future development of Chinese enterprises.
2.3 Strengthen enterprise managers' knowledge and understanding of computer networks.
For any enterprise, a good manager is the core of the enterprise, and in modern society, people pay more and more attention to the management of computer network, and how to get more attention in the fierce competition has become the content of people's concern. Many managers of modern enterprises have a new understanding and view of computer network. People think that computer management is a more scientific technology, and only by making full use of modern management system can we better control the development of computers. Therefore, in the actual enterprise development, we must strengthen enterprise managers' understanding of computer networking. Only in this way can we better realize the long-term development of enterprises in China [3].
3 Conclusion
To sum up, the author briefly discusses the contents of computer network construction in enterprise modernization management. Through the analysis, it can be found that in fact, the modern management of enterprises requires higher operability of computers, and any enterprise wants its products to be unqualified, so it is very important to strengthen the modern management of enterprises. In the future development, people will better realize the development of enterprises and computer network construction, and lay a solid foundation for China's economic system construction.

A paper on computer network: 3000 words. About computer network security and prevention of network attacks.
Introduction to 0
With the development of modern society, computer network information and network have been widely used, and its tentacles have extended to all fields of our lives. However, it is undeniable that there are still serious computer network information and network security problems in China. The main problems are hacker attacks, virus intrusions and malicious spyware intrusions. China's computer network information and network security are facing great challenges. This paper attempts to put forward some feasible computer network information and network security protection strategies to provide ideas for solving the current network information and network security problems.
1 computer network information and network security connotation
Computer information security refers to the comprehensive application of password, information security, data recovery, LAN networking and maintenance, data disaster, operating system maintenance and database application technology to ensure that computer information is not infringed. Computer network security refers to the application of corresponding network management technology to ensure the integrity, confidentiality and availability of network environment data. Computer network security mainly includes logical security and physical security. Logical security refers to ensuring the integrity, confidentiality and availability of information, while physical security refers to ensuring. Physical safety mainly refers to the safety of system equipment and related facilities.
2 Computer network information and network security status
Although experts and all walks of life have paid more and more attention to computer network information and network security in recent years, there are still many problems that cannot be ignored.
First, the defects of computer network information and network security management. Computer network information problems and network security management defects are a problem that could have been avoided. It is due to the neglect, poor management, inadequate management and management defects of related enterprises that computer network information and network security are threatened, measures are not deployed in place, internal information is stolen, system anti-corruption attacks and so on.
Second, it lacks the ability to detect and design the system. It mainly includes code design and security architecture design. Many people who design the system are still weak in information protection awareness, which naturally leads to great security risks in the system designed at this time. Such a design is bound to be vulnerable to some malicious attacks. Many hackers can use some vulnerabilities to attack denial of service, tamper with relevant information and invade the corresponding detection system, which seriously affects the authenticity of information.
Third, the virus. Programs and codes specially compiled by viruses to destroy computers or data have many properties, such as self-replication, infection, parasitism, destruction and so on, and can be spread through data transmission, program operation and so on. Mobile hard disk in daily life is a good way of communication, which poses a great threat to network information and network security.
Fourth, computer electromagnetic radiation leaks network information. The leakage of electromagnetic radiation mainly includes conduction leakage and radiation emission, and the leakage of information security is generally caused by conducted emission. Computer equipment, including monitors, keyboards, mainframes, printers, etc., will produce conducted radiation and electromagnetic radiation to varying degrees when working. In addition, there are also problems such as system vulnerability attack, Trojan horse, Trojan horse attack and network software defects.
3. Computer network information and network security protection measures
Any computer system is not perfect, and there are some loopholes. Inadvertent loopholes and defects in these systems have become channels for hackers to attack. When the system package running on the client or server contains vulnerability code, hackers can use these problems to carry out attacks. Denial of service attack. This is one of the most commonly used attacks by hackers, which usually leads to the following results: the cache of the server is full, and new requests cannot be received, or the connection between the server and legitimate users is affected by IP spoofing. Attackers usually attack the network by making the target host stop providing services in some way. The most common way of denial of service attack is to attack the available bandwidth or connectivity of the network. Denial of service attack has always been an unsolved problem in the network, which is mainly caused by the security defects of the network protocol itself, so denial of service has become the ultimate attack means of intruders.
A computer firewall technology, also known as computer security technology, is mainly used to protect computers and the Internet, enterprise internal networks or individual nodes. Simple and practical firewall has high transparency, and its safety protection device can meet certain safety requirements, even without changing the original network application system. This security technology checks, analyzes and filters the IP packets flowing from the inside when running protection, and shields the information and structure of the protected network nodes and external networks to the greatest extent. On the other hand, some external dangerous addresses are shielded to protect the internal network environment. The principle of firewall security technology is composed of a pair of switches, one blocking signal transmission and the other allowing signal transmission. It represents a principle of network access in computer network, so as to achieve the ultimate goal that a network is not attacked by other networks. In the process of protecting our own network, we often set the security parameters of the firewall, that is, set the external network data except ourselves through firewall rules, set the security policy of our own network to filter and detect network information, release it safely, and block it if there are security problems.
Second, digital encryption technology is to encode important information in the network with special numbers, so that illegal users can't identify this information. In this way, even if illegal users steal the information in the network, they cannot identify the content of the information. Generally, this technology is mostly used in large-scale commercial fields and financial fields, such as international trade orders. With the deepening of internationalization, more and more multinational companies have established branches with local area networks around the world. When communicating with the head office, the branch company must encrypt the important information to prevent the information from being exposed, and ensure the security of the information during the connection between the local area network and the Internet.
Thirdly, computer access control technology is mainly used to solve the problems of network user authentication and what users should do. This is a network access control technology combining strategy and mechanism, which can authorize access to limited resources to the maximum extent. Protecting resources is its biggest feature, which plays a certain role in blocking unauthorized customers who have malicious or unintentional access. Access control technology is the core of computer information security guarantee mechanism. The most important means of computer access control technology is to realize the confidentiality and integrity of data, which is also the most important and basic security mechanism of computers.
Fourth, anti-virus software is a kind of security software that can fully protect the network. For example, software such as Rising Antivirus, Baidu Guardian and Tencent Computer Manager can help network users better protect their data from infringement. Network antivirus software is mainly embodied in virus detection, network killing, prevention of new viruses, virus killing and timely updating. With the rapid development of computer network technology, computer virus has become more and more complex and advanced, which poses a threat to computer network to some extent. Once computer network users find that the system is infected with virus, they should immediately use anti-virus software to deal with it, and delete illegal users in time to understand the degree of system infection, scan out the specific location of the virus and thoroughly clean up the virus. Only in this way can the security of computer network be guaranteed.
Fifth, in order to maintain network information and network security, we should reform and innovate management. It mainly includes revising the management system, improving the safety and management awareness of the corresponding supervisors, backing up information, developing the corresponding supervision and management application system, and strengthening the supervision and control of relevant departments. The first is to modify the management system. Only by paying more attention to the revision of the management system and revising the qualified and applicable management system can we better guide people's actions. The second is to improve the safety and management awareness of the corresponding supervisors, and improve their ability and confidence to cope with difficulties through safety training for relevant personnel.
Secondly, backup information, according to the actual situation of the network, regularly back up some data and materials on the network to prevent the corresponding data and materials from disappearing without warning when a fault occurs. Then, develop the corresponding supervision and management application system. Only a good supervision and management application system can effectively protect network information and network security, so it is necessary to increase the development and research of related technologies. Finally, strengthen the supervision and control of relevant departments, implement the responsibility system, implement the tasks and responsibilities of all parties, and make the management model more advanced and scientific. Sixth, in order to maintain network information and network security, we should strengthen the reliability construction of computer systems. We should pay attention to choosing excellent servers. As we all know, the server determines the quality of the whole network and is the core and key point of the network. Therefore, we should strengthen the construction of server hot plug technology, only input and no output technology and fault tolerance technology, improve the excellent degree of servers and enhance the reliability of computer systems.
In short, with the rapid development of network information technology, we inevitably face some prominent network information and network security problems, including computer network information and network security management defects, lack of detection and design system capabilities, viruses and electromagnetic radiation leaking network information. And solving these problems needs the attention of experts and all walks of life. Only by raising the awareness of network security, developing the security system, strengthening technical research, preventing hacker intrusion, reforming innovative management, strengthening the reliability construction of computer systems, and paying more attention to encryption technology, can computer network information and computer network security be better maintained and developed.
