 0 Introduction
 Under the background of the new era, computer and Internet gradually penetrate all aspects of Human life, and with the frequent occurrences of network security issues domestically and internationally, national politics and the information security of network users have been violated. Based on this, we need to further improve the security defense capabilities of computer networks, commit to building a secure network environment, and prevent the occurrence of network risks.
 1 Measures to Enhance Computer Network Management
 1.1 Strengthen rational network configuration
𝚏𝗿𝗲𝐞𝚠𝕖𝐛𝗻𝗼𝐯𝕖𝚕.𝚌𝗼𝗺 During the use of the Internet by computer users, network configuration has a relatively direct impact on the security of network usage. At the same time, whether the network configuration is reasonable can also have a significant impact on the usage experience of computer network users. Network configuration occupies a central position in network management, its functions include the opening of network services, the establishment of networks, the maintenance of information data, etc. Reasonable network configuration can ensure that computer use is built on a relatively stable network foundation. Besides, network configuration can also provide more convenient network services for computer users, thus ensuring the security of network operation. Based on this, it can be found that network configuration plays a crucial role in network management, and computer users should pay attention to proper network configuration during network operation to obtain a better user experience.
 1.2 Improve the security of computer networks
 Under the big background of informatization construction in our country, network security and management issues have attracted people's attention, hoping to strengthen network management work through improving the security of computer networks. And to improve the security of computer networks, it is necessary to fully understand and make good use of the specific Security Technology related to network management and achieve their good application in network management to give full play to their management characteristics and advantages. At the same time, computer network users also need to strengthen the use of Network Security Technology in the establishment and application of related businesses. When computer network users encounter security failures, they need to make corresponding countermeasure choices for specific problems and implement timely Repair of vulnerabilities to avoid irreparable losses.

 </div> Under the background of the new era, the use of computer networks has become prevalent, and most users store a large amount of important data information in computer networks, so computer network management work is important and necessary. If computer network users cannot timely supervise network security and resolve faults, it may lead to various system faults in computer equipment, and the birth of faults will inevitably affect the normal use of computer equipment. Once more serious network issues occur, it can cause significant losses to computer network users. Based on this, computer network users need to strengthen the application of Fault Detection systems, as they have a relatively obvious application effect in detecting and eliminating system vulnerabilities. Therefore, this system also plays a relatively important role in network management, capable of realizing network fault discovery, elimination, and Repair. Thus, when using equipment and network applications, computer network users should establish a keen awareness of network system faults, regularly use detection software for fault detection, and once a fault is found in the equipment, timely solutions should be taken to Repair it in the shortest possible time to avoid greater losses.
 1.4 Ensuring Network Performance Security
 In the operation process of a computer network, the overall performance and security of network operation are prerequisites for users to have a good network application experience, which can protect network resources and network services. In ensuring network performance security, it is possible to comprehensively obtain and meticulously analyze the current security conditions and risk levels of the network in use, and then make corresponding evaluations of the analysis results, proposing rectification measures based on the specific network operation conditions to ensure security during network operation. When implementing computer network usage, users need to enhance the acquisition, analysis, and research of data information, manage the overall network operating performance, ensure the security of network performance, and thereby guarantee the security of network use for computer users.
 1.5 Updating System Structures and Cultivating Professional Talent
 With the continuous development of computer network technology in our country, and the continuous advancement of information technology, the difficulty of network security management in our country has also increased. Therefore, updating system structures and strengthening the cultivation of professional management talent are of certain importance and necessity. For enterprises using computer networks in the current economic market, these enterprises should particularly emphasize the recruitment of high-quality network management talent by conducting comprehensive research on the current market development situation. Before recruitment begins, a reasonable recruitment plan should be formulated, and the recruitment threshold for professional talent should be appropriately raised during the recruitment process, emphasizing the assessment of professional talent's technical capabilities to attract high-quality network management talent. For the existing network management talent in enterprises, regular training and assessment should also be organized to continuously update the skills of network management talent. Meanwhile, enterprises should also endeavor to enhance the importance given to management work by management personnel, strengthen the performance assessment of network management personnel, and enhance the work enthusiasm of network management personnel to ensure the security of enterprises' computer network operations, preventing irreparable economic and data losses due to network security issues.
 2 Achieving Related Technologies for Computer Network Security
 2.1 Firewall Technology
 The use of firewall technology can effectively ensure security during the use of computer networks. The construction principle is to build a barrier between different networks to achieve the purpose of protecting the internal computer network by intercepting dangerous elements from the external network. The establishment of a firewall has relatively important significance and function in the use of computer networks. It fundamentally blocks the intrusion of internal networks by external networks. In the practical application of firewall technology, the firewall conducts a relatively comprehensive and in-depth examination of external network information. If information meets security requirements, it can pass through the firewall. If external information presents browsing risks, the firewall will intercept it. In summary, the characteristics of using firewall technology are as follows: (1) Firewall technology can control the access process of computer users to all external network points. (2) The application of firewall technology can prevent the leakage of important information within the internal network. (3) Firewall technology can also maintain sub-networks existing in the internal network. (4) Firewall technology has a certain auditing role in the use of computer networks [1]. When choosing firewall technology, computer network users can select from several modes according to the different operating modes of firewall technology. These include application proxy firewalls, packet filtering firewalls, and state monitoring firewalls. Regarding the network structure of firewall technology, it is mainly divided into the following four structural types: dual DMZ network, screened router structure, screened router + dual homed bastion host structure, and screened router + bastion host structure. Computer users can select the most suitable type of firewall technology according to their own equipment and network.
 2.2 VPN Technology
 VPN technology is a remote network connection technology that is currently widely applied in network applications in our country. Its main operation mode is to achieve remote network connection through a public network with higher security. To some extent, this connection method is not particularly distinct from usual network connections. The elements required to achieve VPN technology also overlap with those required for normal network connections, consisting of three parts: clients, servers, and transmission media. However, the difference between VPN technology and ordinary network connection lies in the fact that in achieving network connection, VPN technology uses a tunnel as the transmission channel, and this tunnel is established based on a public network with higher security. The application of VPN technology can effectively enhance the operational security of computer networks, and VPN technology can integrate with data encryption technology and identity authentication technology to prevent data information leakage when computer network users use the network, stop other users from invading internal network information, and achieve a good user experience for computer network users [2].
 2.3 Data Encryption Technology
 Compared to other network security management technologies, data encryption technology has a unique flexible attribute. Its application range is wide, applicable in more open computer network operation processes. The application of data encryption technology provides more noticeable protection for data and information that exhibit strong variability, enabling comprehensive protection measures. In obtaining and analyzing this part of data information, it can be divided into two categorized attack modes, namely active attack and passive attack. For active attacks, this attack mode has the unavoidable property of self, but active attacks can be easily detected during network monitoring. As for passive attacks, this attack mode usually is not easily detected but can be easily avoided through network security technology. The reason why different types of attacks can be detected and avoided during network operation is due to the use of data encryption technology, which can also be divided into two technical parts during analysis [3]. (1) Data encryption technology includes asymmetric encryption, which can also be allocated into two different parts, namely public key and private key. Both types of keys share the same application characteristics in technical application, i.e., they can perform encryption and decryption work. Moreover, the private key can also be used as a public key. However, the distinction lies in the fact that the public key is a key that can be made public to everyone. The use of private keys employs an exchange method to further ensure the safe operation of computer networks; besides, the private key usage has limitations in ensuring no prior key exchange between exchange parties. This asymmetric encryption technology is commonly used in the information exchange between parties or user signing processes. (2) For symmetric encryption technology, the core of this encryption technology is the password. It can also achieve key encryption and decryption. This encryption technology can simplify the encryption process, reduce the possibility of data information leakage, and ensure the privacy of the transmission process through the acquisition of complete data information.
 2.4 Intrusion Detection Technology
 In the application of Intrusion Detection Technology, it can achieve good capture and detection of foreign information. The monitoring system consists of two parts: the detector and the console. The detector is mainly responsible for capturing and detecting data present in the network environment, and once a problem with the data is detected, the detector immediately sends the relevant data information to the console. Regarding the deployment mode of the intrusion detection system, it mainly has the following four modes: (1) This system can achieve internal deployment work of the network system, review the data information returned by the detector, and assess the risk level it can bring, devising corresponding protective strategies based on the conclusions of the analysis process. (2) This system can also be deployed on the external network system, achieving effective blockage of external information by detecting harmful information outside and working collaboratively with firewall technology. (3) The system detector can be deployed outside the firewall system, providing a comprehensive understanding of related technical problems existing in the internal and external networks and achieving more comprehensive solutions. (4) In network operation, the intrusion detection system can be deployed at multiple operating parts of the network, including on the more important operating parts of the internal network, capturing and monitoring all significant information in network operation, laying a foundation for ensuring network security; it can also be installed between sub-networks in different areas of the internal network, receiving and monitoring all information transfers between two sub-networks [4].</div>
