Industrial IoT Security Technologies – Risk Analysis

Industrial IoT Security Technologies : The Internet of Things (IoT) builds on the Internet, through radio frequency identification (RFID) technology, the global positioning system (GPS), and information-sensing devices such as infrared sensors and laser scanners. , any object is connected to the Internet in accordance with the relevant technical protocols, and data communication and information exchange are carried out. 

To carry out data communication and information exchange, and finally achieve intelligent identification, positioning, tracking, monitoring and other functions. However, IoT security risk has become a bottleneck limiting IoT development. IoT is dealing with the physical world, be it smart mobility, smart grid,

Industrial IoT Specific Applications

From the current technology development and application prospects, the specific applications of industrial IoT are mainly focused on the following levels.

Manufacturing supply chain management

Industrial IoT projects are often applied to the company’s raw material procurement, inventory management, after-sales and other aspects, through the specific industrial IoT technology to improve and optimize the entire chain management structure. supply, improve overall efficiency, reduce production losses and management costs.

Optimization of the production process

Through the application of industrial Internet of Things technology, it can optimize the production line testing process, complete the real-time collection of production parameters and real-time monitoring of production equipment, and improve the monitoring level of production material consumption, so as to achieve intelligent monitoring and intelligent control of the production process, the formation of intelligent diagnosis and intelligent decision-making mechanism, so that the intelligent maintenance level of the companies continue to improve.

Monitoring and management of product equipment

Online and real-time monitoring of equipment through sensors and networks, and provision of solutions for equipment maintenance and problem resolution.

Environmental monitoring and energy management

The integration of the Internet of Things and environmental protection equipment performs real-time monitoring of various pollution sources generated in the industrial production process and key indicators in various aspects of pollution control.

Industrial Safety Production Management

The sensors are embedded and assembled in mining equipment, oil and gas pipelines, and mining equipment, which can detect the information of the safety status of personnel, equipment and machines, and the environment in the hazardous environment, and update the platform of existing network supervision into a systematic, open and diversified comprehensive network supervision platform, realizing real-time perception, accurate identification, rapid response and effective control.

Industrial IoT Security Risk Analysis

The three characteristics of industrial IoT are comprehensive perception, reliable transmission, and intelligent processing. The system coordinates the running time between the modules through the network communication protocols, so as to realize self-awareness and judgment, self-regulation and control of the whole system. According to the structure and activity of each level, the industrial IoT can be divided into a comprehensive sensing layer, reliable transmission layer, an intelligent processing layer, and a comprehensive application layer. 

Security risks in the reliable transmission layer

The reliable transmission layer ensures the reliable transmission of sensory data in heterogeneous networks and is equivalent to the network and transmission layers of the TCP/IP architecture, including information transmission and identification, data storage, data compression, etc. data and recovery. The elements that make up this layer include the network infrastructure, the communication protocols, and the coordination mechanisms between the communication protocols. 

Security risks of the intelligent processing layer

The intelligent processing layer is composed of various intelligent processing platforms with different functions, and the computing power of these platforms is deployed and organized in the form of network computing or cloud computing. 

The security risks of the intelligent processing layer mainly include uncontrolled intelligent processing of data, illegal human intervention (insider attack), loss of equipment (especially mobile devices), etc. The risks faced by the introduction of industrial control systems are: the intelligent platform is threatened by viruses; blocking, spoofing, denial of service, etc. cause control commands to be delayed or distorted, making the system unable to enter a stable state; automatic control platform is subject to (controllability is one of the important indicators of industrial safety); low tolerance for catastrophes,

Embedded Application Layer Security Risks

The integrated application layer provides personalized services for end users, including identity authentication and privacy protection, etc. At the same time, it is oriented to the co-processing layer, reserving human-computer interaction interfaces and providing operation instructions to the user, through which the user can access the network using multiple terminals, such as the TV terminal, the PC terminal and the mobile terminal. 

The integrated application layer is characterized by diversity and uncertainty. Different application environments in the industrial field have different security requirements, and the threats they face are also diversified: a large number of terminals, massive data, heterogeneous networks and diverse systems under a variety of different security problems, some security threats are difficult to predict; Data sharing is one of the characteristics of the IoT application layer, but data sharing can bring problems in data privacy, access control, information leak tracking, etc.
