Forensic Copying for Cloud Disk Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital forensics in cloud computing environments face challenges such as resource obstruction and unnecessary resource allocation during suspected breach investigations, as existing methods require direct access to disks for analysis, even if no breach has occurred.
Innovation Solution
The solution involves generating an inspectable disk from a resource's disk in the computing environment, mounting it on a forensic analyzer, and configuring the analyzer to perform forensic analysis without disrupting the original disk, allowing for targeted remediation actions only when a breach is confirmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If forensic analysis is performed directly on the original disk, then analysis accuracy is improved, but resource obstruction and disruption to normal operation occur
Solution Approach 1:
The patent creates a forensic copy (inspectable disk) of the original disk, allowing forensic analysis to be performed on the copy while the original disk continues to operate normally. This resolves the contradiction by enabling accurate forensic analysis without disrupting normal operations, as the analysis is performed on the copied data rather than the live disk.
Solution Approach 2:
The patent separates the forensic analysis function from the original disk operations by creating a distinct forensic copy. This segmentation allows the original disk to maintain its normal operations while the forensic copy handles analysis tasks, eliminating resource obstruction and ensuring operational continuity.
2Loss of time
If forensic analysis resources are allocated proactively, then response time to potential breaches is improved, but unnecessary resource allocation occurs when no breach exists
Solution Approach 1:
The patent prepares forensic copies and analysis resources in advance but only activates them when breach suspicion arises. The system can quickly generate forensic copies and deploy analysis resources when needed, providing rapid response to actual breaches while avoiding continuous resource allocation during normal operations.
Solution Approach 2:
The patent implements dynamic resource allocation where forensic analysis resources are activated only when breach suspicion is detected and deactivated when not needed. This dynamic approach optimizes resource usage by matching resource allocation to actual security needs, reducing waste while maintaining rapid response capability.
3Reliability
If disk access operations are devoted to forensic analysis, then detection capability is improved, but productivity of the original resource decreases
Solution Approach 1:
The patent creates a forensic copy of the disk that can be accessed and analyzed without affecting the original disk's productivity. The forensic copy captures the necessary data for breach detection while the original disk continues to serve its primary functions, thus maintaining both detection capability and resource productivity.
Solution Approach 2:
The forensic copy acts as an intermediary between the original disk and the forensic analysis process. It allows detection operations to be performed on the copy while the original disk remains unaffected, thereby maintaining productivity while improving breach detection capability through dedicated forensic access.
