Industrial Internet Pilot Demonstration · Case Study | Issue 4: Innovative Practices in Network Security Protection for Industrial Control Systems by Luan Technology

With the continuous advancement of the “integration of informatization and industrialization” and the “Made in China 2025” strategy, the level of informatization of industrial control systems has gradually increased, and attacks on industrial control networks have become a norm. Terminal devices, as the “bridge” connecting the information world and the physical world, have become the main target of network attacks and an important “breakthrough point.” Due to the special nature of industrial production environments, the requirements for system stability are extremely high. Industrial terminals cannot perform timely patch repairs or virus database updates like traditional PC hosts through methods such as rebooting, resulting in outdated systems that cannot be updated, low hardware configurations, and limited resources. Moreover, industrial hosts are often left “naked,” unable to update patches, and antivirus software cannot be compatible with updates, leading to numerous vulnerabilities. Therefore, industrial terminal security protection faces significant difficulties and challenges.

Luan Technology conducted on-site research and in-depth communication with industrial control enterprise users to fully understand their needs for terminal network security management. Based on this, they developed industrial terminal network security management products to achieve “installable, usable, and manageable” industrial host security reinforcement.

The host security reinforcement system consists of security subsystems such as whitelist control, integrity protection, identity authentication, peripheral management, security reinforcement, network protection, and log auditing, supporting both standalone and networked deployment schemes. In standalone deployment, the host reinforcement system installed on the industrial host provides a security protection policy configuration interface, and the system protects its operation according to the user’s configured local security policies. In networked deployment, in addition to the host reinforcement systems installed on various industrial terminals, a centralized management platform is provided to uniformly manage all installed host reinforcement systems across different industrial terminals, including the unified issuance of security management policies, security configuration data, software update packages, etc. Meanwhile, each industrial terminal reports its operational status, system logs, and other data to the centralized management platform. The networked deployment model addresses the challenges of managing and maintaining numerous industrial terminals scattered across different regions.
