The 5G era has arrived! What are the security risks of the Internet that we cannot live without?

5G is the English abbreviation of the new generation of cellular communication technology. This is the fifth era of mobile communication technology. my country is currently a leader in 5G technology. China has officially launched 5G packages since October 2019, which marks the official arrival of the 5G era and is far ahead of foreign countries. 5G technology has the characteristics of high data transmission, low latency, high response, and low cost, which has greatly changed our daily life, such as network capacity and network speed.

So what is the 5G era? The 5G era generally refers to the innovation in the cutting-edge fields of information technology today. There are many application scenarios, such as cloud computing, big data, intelligent artificial AI, intelligent driverless cars, and intelligent environmental protection. These are all application levels of 5G technology. my country is currently vigorously developing 5G technology. At the 2020 China 5G+ Industrial Internet Conference, it was stated that a new round of scientific and technological revolution has been launched in the world, and the development of information technology has been greatly improved. The effective combination and development of 5G and China's Internet will promote the development of industries such as digital China, smart society, green energy conservation and emission reduction, and carbon neutrality, and better empower entities, serve society, and benefit the people.

In the 5G era, digital information is becoming faster and more efficient, computer processing speed has made a qualitative leap, networks have become more complex and generalized, and the emergence of endless Internet technologies has made information interaction more secure and convenient. Although the technology is updated too quickly, in actual use, the security issues of 5G data information are becoming more and more serious.

For example, the negative events that Tesla has experienced in recent years have once again brought the issue of autonomous driving and system control of smart cars to the forefront. The autonomous driving and assisted driving of smart cars have certain security loopholes due to the control of computer terminals, and are also the focus of hacker attacks.

In this context, how to maintain data security and privacy while developing 5G technology has become a new issue. Various network threats to the Internet are emerging one after another. For example, the "Eternal Blue" network vulnerability attack incident in recent years directly or indirectly caused more than 8 billion US dollars in losses worldwide. With the update of 5G technology, network attack methods will also adapt to the times and become more complex. People and systems, people and networks, and systems and systems will all be connected at high speed through the network, which also gives hackers and malicious codes more attack opportunities, bringing fatal effects to mobile office security, sensitive data, and even national infrastructure.

With the rapid development of information technology in the 5G era, the number of business information systems, market applications and auxiliary management systems based on wide area networks in many industries in my country has grown rapidly. In order to improve services and processes, various forms of security performance management have been opened, resulting in a large amount of information data leakage. The various network telecommunications frauds that have arisen have had a certain impact on people's daily lives. In daily life, we must overcome the idea of ​​"greed for profit", do not be credulous, and beware of being deceived. Do not believe in news of winning or requesting transfers. If the other party provides information that matches your own, you must guard against it. At the same time, protect your personal information privacy, do not leak your own information at will, and report to the police immediately if you encounter fraud.
