Centralized Security Event Policy for Industrial Asset Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring security for industrial automation environments is challenging due to the need for manual, vendor-specific settings on numerous devices, leading to time-consuming processes and potential human errors, especially when dealing with diverse device vendors and complex network infrastructures.
Innovation Solution
A model-based security policy configuration system that groups industrial devices into security zones using a graphical interface, defines communication policies, and translates these policies into device-specific instructions, abstracting from vendor-specific complexities and enabling centralized management of security event policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual, vendor-specific settings are configured on numerous devices, then security coverage is achieved, but configuration time and human error increase
Solution Approach 1:
The patent introduces a centralized security configuration system that acts as an intermediary between security policies and individual devices. This system translates high-level security policies into device-specific configurations automatically, eliminating the need for manual configuration on each device while maintaining comprehensive security coverage across the industrial automation environment.
Solution Approach 2:
The system enables devices to self-configure by automatically receiving and applying security configurations from the centralized system. Each device can independently implement security settings based on its type and security zone requirements without requiring manual intervention, thereby reducing configuration time and potential human errors.
2Adaptability or versatility
If manual configuration is performed on each device, then vendor-specific requirements are met, but complexity of management increases
Solution Approach 1:
The centralized security configuration system provides a universal platform that can manage multiple vendor-specific device types through a single interface. It automatically adapts security policies to different device vendors and models, maintaining vendor-specific configuration requirements while simplifying overall management complexity through centralized control.
Solution Approach 2:
The system dynamically adjusts configuration parameters based on device type, vendor, and security zone requirements. By automatically modifying configuration parameters for each device according to its specific characteristics, the system maintains adaptability to vendor-specific requirements while eliminating the need for complex manual configuration management.
3Productivity
If centralized policy management is implemented, then configuration efficiency improves, but system complexity increases
Solution Approach 1:
The centralized security configuration system is segmented into distinct functional modules including policy definition, translation engine, device discovery, and configuration deployment. This modular architecture improves configuration deployment efficiency by enabling independent operation of each module while managing system complexity through clear separation of concerns and standardized interfaces between components.

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. Based on the model and these policy definitions, the system generates asset-level security setting instructions configured to set appropriate device settings on one or more of the industrial assets to implement the security event management policies, and deploys these instructions to the appropriate assets in order to implement the defined policies.
