Gateway Module Operating Device States for Unauthorized Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The risk of unauthorized access to manipulation functions in gateway modules communicating with external servers poses a threat to operating safety, as these functions can be accessed and misused to retrieve or influence field data and devices improperly.
Innovation Solution
Incorporating an operating device with visually distinguishable states that allows the manipulation function to be provided or deactivated based on the device's state, ensuring it is only active when intended, thereby enhancing the module's operating safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the manipulation function is provided on the gateway module to enable configuration and control, then the ease of operation is improved, but the risk of unauthorized access increases and operating safety deteriorates
Solution Approach 1:
The patent implements a start-up mode that must be activated before the manipulation function becomes available. This preliminary action ensures that only authorized personnel who can access the start-up mode can enable the manipulation function, thereby preventing unauthorized access while maintaining ease of operation for authorized users.
Solution Approach 2:
The patent provides different access levels and operational modes for different users or situations. The manipulation function is made available with different degrees of access control depending on the operational context, allowing authorized users to access full functionality while restricting unauthorized access, thus resolving the contradiction between ease of operation and operating safety.
2Reliability
If the manipulation function is deactivated to improve operating safety, then the risk of unauthorized access is reduced, but the ease of operation deteriorates
Solution Approach 1:
The patent makes the availability of the manipulation function dynamic rather than static. The function can be activated or deactivated based on the operational mode and authorization status. This dynamic approach allows the system to provide full ease of operation when authorized while maintaining high operating safety when unauthorized access is a concern, thus resolving the contradiction.
3Ease of operation
If the manipulation function is always provided to ensure ease of operation, then the ease of operation is improved, but the risk of unauthorized manipulation increases
Solution Approach 1:
The patent implements preliminary anti-action by requiring activation of the start-up mode before the manipulation function becomes available. This preventive measure counteracts the potential harmful effect of unauthorized manipulation before it can occur, while still allowing authorized users to access the full functionality when needed, thus resolving the contradiction between ease of operation and security risk.

AI summary
A gateway module includes: a module housing, an operating device arranged on the module housing, which can be put, by user actuation, into a plurality of visually distinguishable operating device states, a first communication interface for communication with field level devices, a second communication interface for communication with an external server, and a control unit configured to receive field data from the field level devices via the first communication interface and to provide the field data to the external server via the second communication interface, wherein the control unit is further configured to provide, depending on which operating device state the operating device is in, a manipulation function for influencing the operation of the gateway module and/or the field level devices.
