Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adoption of Industry 4.0 with networked computing devices increases the cyberattack surface in manufacturing environments, necessitating scalable and dynamic policy enforcement that is not efficiently addressed by conventional IP addressing schemes.
Innovation Solution
Endpoint security groups are utilized to classify computing devices by shared features or characteristics, enabling automated policy application and micro-segmentation of data traffic, independent of IP addresses, to ensure fine-grained control and minimize the cyberattack surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional IP addressing schemes are used for endpoint grouping, then network management can be implemented, but the system cannot efficiently address scalable and dynamic policy enforcement in Industry 4.0 manufacturing environments
Solution Approach 1:
The patent segments endpoints into security groups based on functional capabilities rather than IP addresses. This segmentation allows independent policy enforcement for each functional group, improving adaptability while managing complexity through logical organization. Endpoints are classified into groups such as sensors, actuators, controllers, and gateway devices, each with specific policy requirements.
Solution Approach 2:
The patent introduces a security group classification mechanism as an intermediary between endpoints and policy enforcement. This intermediary layer translates diverse endpoint functional capabilities into standardized security group categories, enabling scalable and dynamic policy enforcement without directly managing individual endpoint complexity.
2Object-affected harmful factors
If endpoint security groups are implemented for fine-grained control, then the cyberattack surface is minimized, but the system complexity increases
Solution Approach 1:
The patent applies local quality by assigning specific security policies to each security group based on their functional capabilities and risk profiles. Different device types (sensors, actuators, controllers) receive tailored security treatments appropriate to their local characteristics and potential attack vectors, minimizing the overall cyberattack surface through differentiated security measures.
Solution Approach 2:
The patent changes the parameter basis for endpoint grouping from IP addresses to functional capabilities. This parameter transformation enables more meaningful security group formation that reflects actual device roles and risks, reducing the attack surface while managing complexity through capability-based classification rather than network address management.
3Productivity
If automated policy application is implemented independent of IP addresses, then manual allocation overhead is reduced, but the classification system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-defining security groups based on endpoint functional capabilities before policy enforcement is needed. Endpoints are classified into appropriate security groups during initialization or registration, enabling automated policy application without manual IP address allocation. This preliminary classification reduces operational overhead while managing complexity through standardized group definitions.
Data Source
AI summary
Endpoint security groups include computing device endpoints that are classified according to commonly shared device features and capabilities including device type, function, role, or location. Endpoint security groups are used as an alternative identity mechanism for endpoints for purposes of security and data traffic policy enforcement rather than using conventional IP (Internet Protocol) addressing. Grouping endpoints reduces the scope of network management to enable dynamic policy enforcement for endpoints as they join, leave, and then rejoin computing networks, which is a common behavior, particularly for IoT (Internet-of-Things) devices in manufacturing environments. In an illustrative example, a private multi-access edge compute (MEC) platform supports a scalable policy definition and enforcement framework that provides consistent endpoint handling independent of network access methodology. Endpoint security groups facilitate improvements in security of network access and utilization and segmentation of data traffic on a fine-grained basis.
