How to solve the network security problem?

With the rapid development of industrial Internet, how to solve the network security problem?

Network security has different interpretations in different application environments. For an operating system in the network, network security refers to the security of information processing and transmission. It includes the safe and reliable operation of the hardware system, the security of the operating system and application software, the security of the database system, and the protection against electromagnetic information leakage. The narrow sense of network security focuses on the security of network transmission.

The industrial Internet has broken the relatively independent and pure physical isolation between people and machines, factories and factories, and built a global industrial network. Industrial Internet was included in the government work report for the first time. The development of the industrial Internet can be said to be extremely fast. With the continuous development of "new infrastructure", all walks of life will serve the public in the form of "network+APP", and the impact of network security will be more and more profound.

In 2018, the Network Security Bureau of the Ministry of Industry and Information Technology entrusted relevant professional institutions to conduct security inspection and assessment on more than 20 typical industrial enterprises and industrial Internet platform enterprises, and found more than 2000 security threats. Relevant data shows that more than 50% of industrial control systems in China are operating with viruses, and 100% of industrial control systems are operating with loopholes. New technologies such as the Internet of Things connect the virtual world with the real world. Attacks from the virtual world may turn into injuries to the physical world, such as the power outage in Venezuela and hacker attacks on Ukraine's power grid.

With the rise of cloud computing, the Internet of Things, big data, 5G and other emerging technologies, this security situation may only be the tip of the iceberg. New technologies, new business models, and new application scenarios have brought more and more prominent network security issues. In addition to the security threats of traditional Internet, there may also be security threats of small station access. The network information security boundary is weakening, and the content of security protection is increasing, which poses a huge challenge to data security and information security, and also opens a new incremental space for the network information security market. In addition, with the economic globalization, data security, privacy protection and other issues have been paid more and more attention, and the scale of the network security market has kept growing.

Therefore, network security will become the most important cornerstone of the "new infrastructure" in the future. From the very beginning, the "new infrastructure" should consider adopting China's safe and controllable information technology system to form a new generation of security architecture to ensure the security of infrastructure. If people want to experience the perfect experience brought by smart cities, they must improve the network security system. The 2019 White Paper on China's Cybersecurity Development shows that the size of China's cybersecurity market will reach USD 12 billion by 2021. From 2018 to 2021, the compound annual growth rate of China's cybersecurity market size will be 23.24%, much higher than the global market growth rate.
