Cloud Storage Ransomware Protection via Time-Labeled Backups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antivirus solutions are ineffective in preventing ransomware attacks, particularly in cloud storage systems, as they require frequent updates to combat new types of ransomware and do not provide protection for data stored in the cloud, leading to significant data loss and restoration challenges.
Innovation Solution
A security system that automatically creates backups of files in cloud storage systems at predetermined intervals, detects ransomware applications, blocks their access, and quickly restores infected files with minimal data loss, while monitoring cloud applications and notifying users of security events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antivirus software is used to protect against ransomware, then local devices can be protected to some extent, but the protection becomes ineffective against new ransomware types without frequent updates and does not cover cloud storage data
Solution Approach 1:
The system performs preliminary actions by automatically creating time-labeled backups of cloud storage files before ransomware encryption occurs. The backup mechanism is pre-configured to capture file states at predetermined intervals, ensuring that when encryption attacks happen, restored files from previous backup time labels are immediately available without requiring detection or response time.
Solution Approach 2:
The patent implements copying by creating redundant copies of cloud storage files in a separate backup storage system. These copies are maintained independently and can be restored to their original state before encryption, effectively isolating the primary cloud storage from ransomware damage while preserving clean versions of the files.
2Productivity
If cloud storage systems automatically sync files without intervention, then data availability and accessibility are improved, but encrypted files overwrite previous versions and cause irreversible data loss
Solution Approach 1:
The backup system segments file storage by creating separate backup entries for different time periods. Each backup is associated with a specific time label, allowing the system to distinguish between current encrypted files and previous clean versions. This segmentation enables selective restoration of files from specific time points without affecting the sync operation of current files.
Solution Approach 2:
The system performs preliminary backup actions at predetermined time intervals before encryption occurs. By establishing these time-labeled backups in advance, the system ensures that when ransomware encrypts files during sync operations, the previous unencrypted versions are already preserved and can be restored immediately, preventing information loss.
3Reliability
If manual backup solutions are used, then data recovery options exist, but restoration requires tremendous time and effort
Solution Approach 1:
The system implements self-service by automatically detecting ransomware encryption events through monitoring of cloud storage changes. When encryption is detected, the system autonomously restores files from previous time-labeled backups without requiring user intervention or manual recovery procedures, significantly reducing restoration time and effort.
Solution Approach 2:
The system uses feedback mechanisms to monitor cloud storage file changes and detect encryption patterns. By continuously analyzing file modification events and comparing them against backup versions, the system identifies ransomware attacks in real-time and automatically initiates restoration processes, eliminating the need for manual backup recovery operations.
