Introduction

The Industrial Internet is a new type of infrastructure, application model, and industrial ecosystem that deeply integrates next-generation information and communication technologies with the industrial economy. By achieving comprehensive connectivity among people, machines, objects, and systems, it builds a brand-new manufacturing and service system that spans the entire industrial chain and value chain. It provides a practical pathway for the digitalization, networking, and intelligentization of industries—and serves as a crucial cornerstone of the Fourth Industrial Revolution. However, as the Industrial Internet becomes increasingly widespread and widely adopted, the security threats and challenges it faces are also on the rise. These issues directly impact industrial production efficiency and standards as well as overall safety, making them pressing problems that urgently need to be addressed in the practical implementation of the Industrial Internet.

I. Security Challenges Facing the Industrial Internet

1. Cybersecurity Challenges

The cybersecurity challenges in the industrial internet primarily include cyberattacks, network congestion, and cyber viruses. Cyberattacks can lead to severe consequences such as system crashes and data breaches; network congestion may slow down data transmission rates, thereby affecting production efficiency; and cyber viruses can paralyze systems, causing serious disruptions to production. Moreover, cybersecurity issues can also trigger cascading effects, potentially leading to the collapse and paralysis of entire production systems. The cybersecurity risks commonly discussed in the context of the industrial internet not only involve the industrial and internet components themselves but sometimes extend to commercial networks as well. During the industrial production phase, if data transmitted via internet-based information technologies is compromised or if the transmission of such data is not authorized by the industrial internet service system, security vulnerabilities are likely to arise. Additionally, hardware and software issues within the internet systems themselves, as well as vulnerabilities in application software used in industrial production, all pose significant cybersecurity challenges for the industrial internet. Beyond these factors, the use of wireless systems and internet technologies can also create ambiguous security risks, blurring the boundaries of industrial internet protection.

2. Data Security Challenges

The industrial internet involves extensive data transmission and processing, including production data, inventory data, management data, equipment data, marketing data, user data, and more. These data not only touch upon companies’ commercial secrets but may also implicate national security issues. Therefore, data security is one of the major challenges facing the industrial internet. On the one hand, data leaks and tampering could lead to significant losses for businesses and increase risks to national security; on the other hand, data encryption and access control are difficult to implement effectively, making it challenging to ensure data’s security and integrity.

3. Application Security Challenges

The application of the Industrial Internet involves a wide variety of business scenarios and processes, such as manufacturing, inventory management, logistics management, marketing services, and application services. These applications not only pertain to enterprises’ core business operations but may also touch upon issues like users’ personal privacy. Therefore, application security is one of the significant challenges facing the Industrial Internet. First, application vulnerabilities can lead to data breaches and system crashes; second, controlling application permissions is quite challenging, making it difficult to fully ensure the security and stability of applications.

4. Physical Security Challenges

The physical security issues of the industrial internet primarily include equipment security, personnel security, and environmental security.

The equipment used to support industrial production has “smart chips” embedded in its core components. However, the use of smart chips carries potential risks—particularly in the chip’s coding section, where problems can easily arise. Once a vulnerability in the chip’s coding is exploited or the chip’s coding is maliciously attacked, it could directly disrupt the operation of the industrial internet and even bring the entire industrial production process to a standstill. As for personnel safety, factors such as the technical expertise of staff, human-induced threats, and accidental incidents can all pose risks. Environmental safety, on the other hand, is primarily affected by factors like pollution and climate change.

II. Response Strategies for Industrial Internet Security

1. Establish a comprehensive cybersecurity system.

To address cybersecurity challenges, it is essential to establish a comprehensive cybersecurity framework. On the one hand, we should strengthen the deployment and application of security devices such as network firewalls and intrusion detection systems to guard against cyberattacks and virus intrusions. On the other hand, we need to develop robust cybersecurity management policies and technical standards to enhance oversight and control over network security. In addition, we should reinforce backup and maintenance management for network equipment to improve network availability and stability. In the international industrial control sector, more sophisticated defense architectures are commonly employed, as illustrated in Figure 1. For the Industrial Internet, network segmentation typically involves dividing the network into several zones: the enterprise network zone, the control network zone, the external zone cluster, the production site, and the remote access zone. By placing firewalls at the boundaries between these zones—isolating the control network from the production zone, the control system network from the remote access zone, and other networks from the enterprise network—we can ensure that all internal systems remain protected against unauthorized external intrusions and attacks.

2. Strengthen data encryption and access control

To address data security concerns, it is essential to strengthen data encryption and access control. On the one hand, advanced encryption technologies should be employed to encrypt data, thereby ensuring its security and integrity. This includes functionalities such as sensitive data discovery, data classification and tiered management, data de-identification/encryption, and monitoring and management of data flow. On the other hand, a comprehensive permission control mechanism should be established to strictly regulate data access and usage, thus mitigating the risks of data leakage and tampering. At the same time, continuous monitoring and analysis of abnormal data should be enhanced to promptly identify and address potential security threats, thereby reducing the risk of data breaches.

3. Strengthen application security management

To address application security issues, it is essential to strengthen application security management. On the one hand, we should enhance vulnerability risk management throughout the application coding process by strictly adhering to relevant management standards from the very initial coding stage. Regular vulnerability scans and risk assessments of application systems should be conducted to promptly identify and address potential security vulnerabilities. On the other hand, we need to establish and refine a comprehensive application access control mechanism, exercising strict oversight over application access and usage to prevent serious impacts on production systems caused by application vulnerabilities or improper permission controls.

4. Enhance physical security protection capabilities

To address physical security concerns, it is essential to enhance physical security protection capabilities. On the one hand, we should strengthen the security safeguards for equipment operating environments—including measures to prevent natural disasters, as well as monitoring and maintenance management of equipment operating conditions—to ensure that equipment operates normally without being affected by force majeure factors such as adverse natural conditions. On the other hand, we should intensify monitoring and management of environmental protection and climate change to reduce the impact of environmental factors on equipment operation and production processes. At the same time, we must reinforce the protection and management of personnel safety, establish comprehensive safety management systems, raise employees’ safety awareness and operational proficiency, and minimize the impact of human errors and accidental incidents on the production system.

5. Establish a comprehensive industrial internet defense plan.

A comprehensive industrial internet defense solution primarily focuses on the following three aspects:

(1) In terms of emergency response management;

(2) In terms of building a data-driven network management security framework;

(3) Regarding the industrial internet organizational personnel team.

Regarding the first aspect, management personnel in industrial production enterprises must transform their existing emergency response management model to enable timely and real-time responses. If, prior to the transformation of the management model, the industrial enterprise’s internet information system has already been subjected to a malicious cyber intrusion, professional technical staff should immediately be dispatched to repair and maintain the compromised internet information system. At the same time, multiple internet defense systems should be established, leveraging situational awareness technology to monitor the industrial control system environment in real time and promptly issue alerts upon detection of external attacks. As for the second aspect, industrial production enterprises must assign dedicated management personnel to conduct regular monitoring, inspection, and maintenance of their internal network systems, thereby ensuring the security of data stored in the internet information database. Furthermore, comprehensive tracking of any hacker attacks that have already occurred must be carried out, and the tracking information should be handed over to the national cybersecurity authorities for resolution. In the third aspect, management personnel are required to adopt scientific and rational approaches to managing team members. Governments and enterprises should regularly organize training sessions on industrial internet system information security, providing learning platforms for enterprises and relevant technical personnel, so that every member of the internet organization’s team can proactively engage in safeguarding the security of internet information systems.

III. Conclusion

In summary, with the rapid development of China’s economy and advances in network information technology, the industrial internet has gradually begun to be adopted by industrial enterprises in China’s daily production processes. Although this adoption has significantly boosted enterprise productivity, numerous security challenges still remain. Therefore, Chinese industrial enterprises should intensify their research and exploration into the industrial internet. By strengthening proactive management of potential security risks, improving network segmentation protection systems, and ensuring the secure remote access to the industrial internet, enterprises can further enhance their productivity and promote their healthy, long-term development.
