Security Management Unit Switching Monitoring for Safe Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security management techniques for information processing apparatuses do not adequately control access in safe mode environments, compromising security and impeding system recovery.
Innovation Solution
An information processing apparatus with a detection unit to identify operating modes and a security management unit that switches monitoring units accordingly, enabling high-security access control in both normal and safe modes by using file system filter drivers and device managers to manage and restrict device usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same security management unit is used in both normal mode and safe mode, then security control is consistent, but the purpose of safe mode (system recovery) is impeded and security may compromise system stability
Solution Approach 1:
The patent divides the security management function into two separate monitoring units: a first monitoring unit for normal mode and a second monitoring unit for safe mode. This segmentation allows each unit to be optimized for its specific operating context, enabling security control consistency while preserving safe mode's system recovery capabilities.
Solution Approach 2:
The patent implements dynamic switching between monitoring units based on the operating mode. The security management unit detects whether the system is in normal mode or safe mode and automatically switches between the first and second monitoring units accordingly. This dynamic adaptation resolves the contradiction by providing mode-appropriate security monitoring without compromising safe mode functionality.
2Ease of operation
If minimum modules are activated in safe mode, then system recovery is enabled, but security function is compromised
Solution Approach 1:
The patent introduces a second monitoring unit that acts as an intermediary specifically for safe mode operations. This unit is designed to work with the minimal module configuration of safe mode, providing appropriate security monitoring that is adapted to the reduced functionality environment while still maintaining security control.
Solution Approach 2:
The patent changes the monitoring parameters and approaches based on the operating mode. In safe mode, the second monitoring unit employs monitoring strategies suitable for minimal module configurations, adjusting security checks to work within the constraints of safe mode while still preventing security breaches.
3Reliability
If comprehensive security monitoring is implemented, then security level is high, but system complexity increases
Solution Approach 1:
The patent segments the security monitoring functionality into two specialized units rather than one comprehensive unit. Each monitoring unit is designed to handle specific security aspects appropriate to its operating mode, reducing the complexity burden on any single unit while maintaining overall high security levels through coordinated operation.

AI summary
When security software is activated, it is determined whether the mode is a safe mode or a normal mode. And the security software switches a monitor in accordance with the mode.
