Due to the prevalent automation equipment and applications in industrial control networks, there are significant differences in the technical execution process compared to the traditional information field. Therefore, in the design of the safety system for industrial control systems, it is necessary to adopt the concept of "one center, three levels of protection" based on hierarchical protection, utilize *safety technologies tailored to the industrial sector, and implement security measures by region and hierarchical levels.

Key Points for Designing a Secure Communication Network

Deploy industrial control system firewalls between industrial control systems and other systems to achieve unidirectional technical isolation.

Deploy industrial control firewalls at the boundaries of different security domains to manage risks of communication links.

Modular application of industrial control firewalls or the use of standalone devices to encrypt wireless transmission processes ensures the integrity and confidentiality of data during communication.

Key Design Points for Safe Zone Boundary

Deploy industrial control system firewalls between industrial control systems and other systems to achieve network boundary isolation and access control.

Deploy industrial control firewalls within the production area between various security domains, implementing fine-grained control over access behaviors between the domains.

Deploy industrial control system auditing and log auditing to audit and analyze user behavior and security events.

Deploy industrial control system intrusion detection and auditing systems to detect, analyze, and prevent external or internal initiated network attacks.

Key Points for Designing a Secure Computing Environment

Install the Industrial Host Guardian software on industrial mainframes to control host applications and processes, peripheral interfaces, mobile storage devices, etc., and audit user operational behaviors.

Deploy an operation and maintenance audit system, utilizing a combination of passwords, biotechnology, and other password technologies for user authentication, and managing user login and logout processes.

Deploy industrial control system vulnerability scanning, perform security assessments on known vulnerabilities, and conduct safety checks on control equipment prior to deployment.

Modules using industrial control firewalls or independent devices ensure the integrity and confidentiality of critical data during transmission.

Key Design Points for Security Management Center

Deploy an industrial control system (ICS) security centralized management platform to monitor the operational status of security devices or components in the network, conduct correlation analysis of device logs, and centrally issue security policies.

Deploy Industrial Control System (ICS) Situational Awareness Systems to monitor, analyze, and issue warnings for ICS networks, or drive security emergency response procedures, supporting emergency response, handling, and traceability in security management and operations.
