Storage Restart Control for Abnormal Read-Write Lockout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data protection mechanisms for storage devices are inadequate in preventing malicious access and ensuring data security, as they fail to effectively detect and respond to abnormal read-write operations.
Innovation Solution
A control system and method that includes a host, first and second controllers, a determining circuit, and a restart input module to detect abnormal read-write operations, disable affected storage devices, and require manual intervention via the restart input module to re-enable them, thereby enhancing data security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data protection mechanisms are used for storage devices, then the system structure remains simple, but the security level against malicious access is insufficient
Solution Approach 1:
The control system is segmented into multiple independent components: host, first controller, determining circuit, second controller, and restart input module. Each component has a specific function in the security chain, allowing the system to achieve high security through modular architecture while maintaining manageable complexity through clear division of responsibilities.
Solution Approach 2:
The determining circuit acts as an intermediary between the first controller and the second controller. It receives abnormal operation signals from the first controller and translates them into control signals for the second controller, providing a dedicated security monitoring layer that enhances data protection without requiring direct complex interactions between all system components.
2Reliability
If storage devices are disabled during abnormal operations to improve security, then data security is improved, but the productivity and accessibility of storage devices deteriorate
Solution Approach 1:
The storage device control state is made dynamic rather than static. The second controller can dynamically switch between enabled and disabled states based on real-time security conditions detected by the determining circuit. This allows the system to maintain high productivity during normal operations while quickly transitioning to a protected disabled state when security threats are detected.
Solution Approach 2:
The system implements a feedback mechanism where the determining circuit continuously monitors storage device operations, detects abnormal patterns, and provides feedback signals to the second controller. This closed-loop control ensures that productivity is maintained during normal operations while security is automatically enforced when abnormal conditions are detected, balancing accessibility and protection.
3Speed
If automatic disabling is implemented upon detecting abnormal operations, then the response speed to security threats is improved, but the ease of operation and recovery of storage devices deteriorates
Solution Approach 1:
The restart input module is pre-configured and physically accessible before any abnormal operation occurs. This preliminary preparation ensures that when a security threat is detected and the storage device is automatically disabled, the recovery process can be quickly initiated through this pre-positioned interface, maintaining ease of operation despite the automatic disabling mechanism.
Solution Approach 2:
The system implements self-service security management where the determining circuit automatically detects abnormal operations and triggers the disabling action without human intervention. The restart input module then allows authorized users to self-service the re-enablement process by simply operating the module, eliminating the need for complex manual recovery procedures while maintaining fast response to security threats.

AI summary
A control system and a control method are provided. The control system provides a first setting signal in response to an abnormal read-write operation performed on at least one storage device. The control system generates a first state signal having a first logic value in response to the first setting signal and latches the first state signal, and disables the at least one storage device on which the abnormal read-write operation is performed in response to the first state signal having the first logic value. The control system includes a restart input module. The restart input module converts the first logic value of the latched first state signal into a second logic value, so that the control system restarts the at least one storage device disabled in response to the first state signal having the second logic value.
