Security Module Alert Level Visual Cue Data Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data security management systems are inadequate in preventing data leakage, as applications with high authority levels can access and copy sensitive information from high-security files and transfer it to lower-security storage, allowing unauthorized access by applications with lower authority levels.
Innovation Solution
A computer system with a module that determines an alert level for applications based on previous and current security zones accessed, providing visual cues to users through a user interface, and controlling write privileges to prevent insecure data transfers by updating restriction levels and notifying users of potential data leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an application with high authority level accesses high-security files and creates or copies files to lower-security storage, then the application can perform useful data processing operations, but data leakage occurs and confidential information becomes accessible to applications with lower authority levels
Solution Approach 1:
The system performs preliminary actions by determining the restriction level of an application based on its authority level before the application accesses security zones. The module proactively sets restrictions on which security zones the application can access, preventing potential data leakage before it occurs. This is done by comparing the application's authority level with the security levels of available zones and pre-authorizing access only to appropriate zones.
Solution Approach 2:
The module continuously monitors and updates the restriction level of applications based on their current activities and previously accessed security zones. When an application accesses a security zone, the module provides feedback by updating the application's restriction level to reflect the highest security level accessed, thereby dynamically adjusting access permissions to prevent data leakage while allowing legitimate operations.
2Reliability
If the system implements strict access control to prevent data leakage, then data security is improved, but legitimate data processing operations between security zones are blocked
Solution Approach 1:
The system dynamically adjusts the restriction level of applications based on their current activities and access history. Instead of static access control, the module continuously updates restriction levels as applications access different security zones, allowing legitimate data processing operations while maintaining security. This dynamic approach enables applications to access multiple security zones appropriately without requiring manual reconfiguration.
Solution Approach 2:
The module changes the access parameters (restriction levels) of applications based on their authority levels and accessed security zones. By modifying the restriction level parameter dynamically, the system allows applications to perform useful data processing operations across appropriate security zones while preventing access to unauthorized zones, thus balancing security with operational flexibility.
3Reliability
If the system monitors and tracks all application access to security zones, then data leakage can be detected and prevented, but system complexity and processing overhead increase
Solution Approach 1:
The module implements local quality by applying different restriction levels to different applications based on their specific authority levels and access patterns. Instead of a blanket security approach, the system tailors access restrictions to each application's needs and security requirements, simplifying security management while maintaining effective monitoring and control.

AI summary
The disclosed subject matter includes a method. The method includes determining, by a module running on a computer platform in communication with non-transitory computer readable medium having a plurality of security zones, whether an application instance is in a foreground of a user interface for the computer platform. The method further includes determining, by the module, an alert level associated with the application instance in the foreground of the user interface, wherein the alert level includes at least one of a restriction level and an access level. The method also includes providing the alert level to a user of the computer platform using a visual cue displayed on the user interface.
