With the rapid development of computer technology, the nation's Computer Network Technology has also made great progress. Computer Network Technology has been widely applied across information systems in various industries, bringing revolutionary breakthroughs to the nation's socio-economic development. This paper analyzes the main factors affecting Computer Information Security, explores countermeasures for Computer Information Security, and ensures the information security of computer networks.

I. Factors Affecting Network Security

1. Hardware and natural environment. In the era of rapid information development, traditional information storage methods may no longer meet the needs of large enterprises. Computer information systems and hardware equipment are inseparable; many data in the hard drive can be accessed mutually within the computer network. Protection measures for hard drive data directly affect the information security of the computer system. Natural factors also significantly impact the computer system; higher operating temperatures may lead to frequent security failures in computers, with possibilities of data loss during operation, negatively affecting the protection of computer network information security.

2. Irrational operation. Most network users do not have a detailed and comprehensive understanding of computer use processes and methods, which subsequently affects the security of computer network information. If users leak their bank card numbers, identity information, etc. in the computer network environment and are leaked by illegal users, it will severely impact the user's critical information security. When users search for relevant information online, if they download certain applications carrying Trojan horses and viruses, it will pose a severe threat to computer network information security.

3. Virus invasion. The invasion of computer viruses brings immense harm to computer networks, and severely can directly lead to national social stability and economic loss. Severe computer viruses can cause the entire computer network to be paralyzed, thus causing serious security implications for the computer network. Virus manufactured by hackers can spread through multiple channels in the network; once the host in the network is infected with a virus, it may be processed as scrap, and the information inside will be unrecoverable, resulting in irreparable loss to the network users.

4. Operating system vulnerabilities. If computer system vulnerabilities are not promptly patched, it will result in serious security issues. Most computer operating systems are still foreign systems, which generally have computer system vulnerability issues, posing significant security risks to computer network information.

II. Protective Measures for Network Security

1. Establish a perfect defense system. Computer network threats are behaviors that endanger computer network information security; we should strengthen the awareness of safe use of computer networks and enhance the anti-virus capability of computer networks by establishing a comprehensive defense system to protect the network. First, computer users should be familiar with the challenges and risks faced by computer network information security, managing the security of important accounts like their bank account online, and regularly modifying their computer system login passwords, avoiding browsing malicious links to reduce the risk of privacy information being stolen. Network information security providers should clarify the computer network security responsibility their enterprises bear and comply with the relevant laws and regulations of computer network security. It's important to value the maintenance of computer network facilities, fully utilize existing Network Security Technology to protect information security, apply various network security mechanisms, and comprehensively construct a computer network information security system. Enhance the defense Level of computer network firewalls; firewalls strengthen security Control in computer network access processes. The role of firewalls is to improve the security of computer network information, playing a significant part in the protection of computer network information security. Ensure the use of Antivirus software to conduct regular virus scans; in the event of attacks from Trojan horses and viruses, Antivirus software can perform virus checks at the computer network terminals and cooperates with firewalls to protect the computer network.

2. Data Encryption Technology. In Data Encryption Technology, mature examples include the Public Key Cryptosystem and the Private Cryptography System, which further safeguard computer network information security through Data Encryption Technology. Implementing data password technology involves employing various encryption methods and channels for multiple layers of encryption protection on computer network information communication. Combine every access step with identity authentication and password encryption verification to ensure a threat prevailing in the computer network guarantees that computer network information is not stolen. Fully leverage Digital signature encryption technology; Digital signature allows computers to identify its electronic signature information in massive network information. The party of the digital signature can accurately send the user's identity, the digital signer can accurately identify the source of the information, and without the sender's permission, the receiver of the digital signature cannot tamper with the information. Biological Identification technology is widely used in the digitized life of computer networks; as future life becomes increasingly inseparable from computer networks, research on advanced and efficient Data Encryption Technology and Biological Identification technology is necessary.

III. Conclusion

In summary, regarding the issue of computer network information security, relevant research and practitioners should study and analyze from different perspectives, grasp the potential risks of computer network information security, and improve the computer network environment from the source to enhance the national information security protection engineering construction.

Introduction

With the development of information technology, the application of computers in various domains of life continues to mature. The level of information technology brings comfort to people's lives, but it also brings some potential security risks. Currently, network security incidents occur frequently, and it is necessary to use scientific methods to improve the security of computer network information technology and eliminate the security hazards in network information technology.

1. Factors Affecting Computer Network Information Technology Security

(1) Attacks by Hackers and Viruses

When managing computer network information, malicious attacks by hackers and infections by various computer viruses are the most common security risks. Some hackers rely on their exceptional computer skills to illegally log into servers, steal personal information from other people's computer networks, and interfere with the normal use of computer network information by others, seriously threatening the confidentiality and security of personal privacy. Therefore, the harm of computer network viruses cannot be underestimated. If a computer is infected with a virus, it will severely impact the security management of computer network information technology. As computer network information technology continues to develop, computer network viruses are constantly being updated and upgraded, and the types of viruses are increasing, making them more difficult for people to identify. Most virus invasions are silent; computers can become infected through emails and web logins. Some viruses have the function of hiding in important computer files and automatically starting, potentially damaging the core data programs of the computer. Certain viruses use computer programs to control the computer and affect data transmission, thereby committing illegal acts of stealing computer network information.

(2) Vulnerabilities in the Computer Network System Itself

It is well known that computer network information systems have strong openness, allowing them to absorb data information from various aspects of the Internet. However, it is precisely due to this openness that the threshold for accessing the internet is very low, and the network information system itself has technical shortcomings, leading to hidden dangers in computer network information security. The security level of the network protocol used to operate internet information is very low, which can cause operational vulnerabilities in computer network information technology systems and further exacerbate the security risks of computer network information systems.

(3) Risks of the Computer Operating System

Currently, computer network information is open to computer users nationwide, and the domestic computer penetration rate has significantly increased. However, among computer users, there are many elderly, teenagers, or people with lower levels of education who are completely unfamiliar with computer operations and even lack awareness of defending against computer viruses. Their ability to recognize network traps is very poor, making it difficult to distinguish malicious code from normal data when using computers, leading to their computers being heavily invaded by malicious computer viruses. This frequent viral attack on computers can cause computer systems to crash, providing criminals and maliciously implanted viruses the opportunity to commit crimes.

2. Security Precautions for Computer Network Information Technology

(1) Network Encryption

Network encryption, also known as network-level encryption and network layer, is a solution to network vulnerabilities. Currently, most network encryption uses the same key for symmetric encryption, where decryption and encryption both use the same key. This encryption method is characterized by simplicity and speed. When using symmetric encryption, the key length must be less than 256 bits, because if the key is too large, the decryption and encryption process will be difficult and time-consuming. Thus, setting the key size within this range helps improve the efficiency of the security protection work for computer network information technology. For network vulnerabilities, symmetric encryption technology is a more effective and in-depth preventative measure. Its simple and replicable operation process is easily accepted and used by the public, and it is highly efficient, making it widely usable for preventing network vulnerabilities. In addition to symmetric encryption technology, the international data encryption algorithm is also a network encryption method that offers more outstanding encryption performance; however, its requirements for computer network information technology are lower, and it can also play a certain role in preventing network vulnerabilities.

(2) Using Antivirus Software and Firewalls

Installing antivirus software is the most common method for preventing computer network viruses. However, there are still some viruses that are difficult to be completely removed by such software, such as mining viruses and ransomware viruses. Currently, China is still in the development and improvement stage of virus prevention. Hackers often exploit the vulnerabilities in antivirus software to steal information, thus requiring the use of firewalls for comprehensive protection of computer network information. Firewalls can use various information protection methods to ensure the security of computer network information technology. Firewalls can be continuously improved as computer network systems are updated and can quickly automatically identify illegal intrusions by viruses and hackers, offering high security, playing an important role in computer network information technology security. It is essential to ensure the security of computer network information technology during computer usage, so it is necessary to clearly define the factors affecting computer network information security and understand the specific methods to eliminate security hazards in computer network information. Through network encryption, proper use of firewalls, antivirus software, and timely backups of data information can effectively improve the security of computer network information.

1 Importance and Security Risks of Computer Network Information Security Protection

1.1 Importance of Computer Network Information Security Protection. The issue of computer network information security is currently an important problem threatening people's privacy and security; hence, strengthening the implementation of computer network information security protection work is particularly important. The application of computer network technology combines computer and communication technology and connects with network protocol implementation to facilitate information transmission. Although this brings corresponding convenience to people's life and work, information security protection work cannot be delayed[1]. The resource sharing of the network is a notable feature, forming a critical basis for network attacks. Thus, some lawbreakers apply network technology to disrupt the privacy information transmitted over the network, which can likely lead to relevant security risks. The current combination of computer networks and domains like finance is becoming increasingly close, further emphasizing the importance of information security protection. The security of computer network information concerns the country's development, which is also a crucial reason for intensifying security protection efforts.

1.2 Security Risks of Computer Network Information. First, the security risks posed by viruses and hackers. The security hazards in computer network information are multi-faceted, with the most common being the attacks from viruses and hackers. Computer network viruses pose a significant threat to network information security, as network viruses have strong transmission and destruction capabilities and have a latent nature, making them difficult to detect. Once computer viruses are discovered, they may cause information damage or loss, and in severe cases, lead to network system paralysis[2].
