With the continuous updating and development of network technology, the use of computers has not only effectively changed people's lifestyles, but also posed new challenges to network security. With the increasing popularity of computer use, people pay more attention to the privacy and security of data information . However, the traditional network security model is no longer able to adapt to the development needs of the new era and cannot achieve reasonable protection of data information. The use of blockchain technology can not only effectively improve computer information exchange capabilities, but also effectively protect network applications. Therefore, using blockchain technology to protect computers has high application value.
Blockchain technology is mainly a decentralized distributed ledger technology, which can effectively solve the problem of network trust. The use of blockchain technology achieves effective protection of data information through encryption, ensuring the privacy of data and ensuring the fairness and accuracy of data records. Therefore, research on blockchain technology should be increased to ensure that its application advantages are fully utilized, so that network security problems can be effectively solved. This article carries out a specific analysis and discussion of network security technology based on blockchain technology.
1. Main risks in network security
The Internet is a double-edged sword. While it brings convenience to people's lives, it also brings risks to people's data and information storage. With the continuous updating of network information technology and the increasing amount of data, this risk will become stronger and stronger. Among them, network security mainly includes: network structure security, network operating system security, software application security, management security and other aspects. Although the network system has huge functions, it is relatively fragile. If corresponding security protection measures are not taken, once it is attacked by an external attack, it will affect the stable operation of the entire system, and even cause system paralysis in severe cases. In addition, if the security level in the local area network is set low, it will easily cause data leakage, cause equipment failure, and cause immeasurable economic losses to users. In addition, the function settings of some systems are still imperfect and there are settings loopholes, which in turn increases the risk of computer use. Although corresponding security protection measures have been taken, the effect is not obvious and the network security problem cannot be fundamentally solved.
2. Characteristics of blockchain
Blockchain technology was not initially applied to computer security, but to Bitcoin. It is a decentralized database that uses a point-to-point method to complete data transmission, and then connects it through a special password. The composed modules form a data network. Therefore, the security performance of blockchain technology is generally high, making the system more independent and less susceptible to other factors. In addition, blockchain technology also has the function of a database, can realize data sharing, and also has a certain degree of openness. When using it, users only need to obtain a port, and in order to ensure the security of user data, trust is mainly given to the third-party machine system, thus maximizing the protection of user privacy. Although blockchain can achieve the purpose of protecting data information to a certain extent, there are still certain flaws. The flaws of blockchain technology itself will also affect the performance of network security protection. Therefore, in specific applications, the impact of defects on the application performance of blockchain technology should be avoided to the greatest extent to ensure efficient protection of the network.
3. Application of blockchain technology in network security
(1) Can enhance the storage and sharing capabilities of network data
Data information can provide better services for related work, and different work stages have different needs for data. The use of blockchain technology can not only achieve high-level protection of data information, but also achieve data sharing, thus facilitating the exchange of data. Therefore, relevant departments can use blockchain technology to complete data supervision and management.
For example: For power grid enterprises, their data scale is generally relatively large, and traditional security protection measures are still relatively low-level, resulting in power resources being easily leaked and being attacked by criminals. With the continuous updating and development of information technology, the use of blockchain technology can effectively achieve reasonable protection of power grid resources, provide convenience for the convenient circulation of power energy in the network, and reduce reliance on intermediaries . This also reduces the risk of data information being stolen , thereby effectively improving the competitive advantage of power companies.
(2) Blockchain builds a more complete social network
The main feature of blockchain technology is that it has a decentralized network system, so that users' online behavior is no longer subject to the supervision of the website system, which also reduces the risk of data information leakage . By using blockchain technology, users can achieve reasonable control over their own network data information and encrypt it, thus providing users with a more secure and private network environment.
For example, for social activities such as voting, likes, or comments on the Internet, blockchain technology can be used to convert them into virtual currency on the Internet. At this time, there is no need to worry about information being tampered with. In addition, corresponding user conventions should be established to ensure that network users' online behavior can be regulated, so as to effectively protect network security.
4. Conclusion
Continuously applying blockchain technology to network security protection plays a vital role in effectively achieving good protection of computer networks, avoiding network system paralysis, and effectively improving the security and privacy of user data information. . Therefore, we should first recognize and understand the main risks of network security and the characteristics of blockchain technology, and then improve blockchain technology from two aspects: enhancing the storage and sharing capabilities of network data and building a more complete social network with blockchain. The application advantages of chain technology in network security ensure the comprehensive protection of computer networks.
