Solution Overview
Problem
Configuring security for industrial automation environments is time-consuming, requires specialized knowledge, and is prone to human error due to the need for manual configuration of numerous devices from different vendors, often leading to communication issues and security vulnerabilities.
Innovation Solution
A model-based security policy configuration system that inventories industrial devices, allows users to group them into security zones, and automatically generates vendor-specific configuration instructions to enforce plant-wide security policies and event management, abstracting technical complexities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of security settings is performed for each industrial device, then security policy implementation is achieved, but time consumption and complexity increase significantly
Solution Approach 1:
The system enables self-service by allowing new devices to automatically enroll and configure themselves with appropriate security policies. The device discovery component detects new devices, and the system automatically retrieves device definitions and applies security configurations without requiring manual intervention, thus reducing configuration time while maintaining security reliability.
Solution Approach 2:
The system performs preliminary action by pre-defining device definitions with associated security policies in a database before devices are deployed. When devices are discovered, the system can quickly match them to predefined definitions and apply configurations immediately, eliminating the need for time-consuming manual configuration while ensuring consistent security policy implementation.
2Reliability
If manual configuration of security settings is performed for each industrial device, then security policy implementation is achieved, but complexity and error rate increase
Solution Approach 1:
The system introduces an intermediary security policy configuration system that acts as a mediator between devices and security policies. This central system manages device definitions, discovers new devices, retrieves appropriate security configurations, and automatically applies them to devices. This intermediary approach simplifies the configuration process by eliminating the need for users to manually configure each device, thereby reducing complexity and minimizing human error while maintaining reliable security policy implementation.
3Productivity
If automatic device enrollment is implemented, then configuration time is reduced, but security policy selection accuracy must be ensured
Solution Approach 1:
The system implements feedback mechanisms where the device discovery component continuously monitors the control network for new devices, and the security policy configuration system automatically responds by retrieving device definitions and applying appropriate security configurations. This automated feedback loop ensures rapid device enrollment while maintaining accuracy through systematic matching of devices to their corresponding predefined security policies based on device identifiers and characteristics.

AI summary
A model-based industrial security policy configuration system implements a plant-wide industrial asset security policy in accordance with security policy definitions provided by a user. The configuration system models the collection of industrial assets for which diverse security policies are to be implemented. An interface allows the user to define zone-specific security configuration and event management policies for a plant environment at a high-level based on a security model that groups the industrial assets into security zones. When new industrial devices are subsequently installed on the plant floor, the system determines whether a security policy defined by the model is applicable to the new device and commissions the new device to comply with any relevant security policies. This mitigates the necessity for a system administrator to manually configure individual devices to comply with plant-wide security policies.
