NAS Malware Scan Status Data Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional malware scanning techniques in data storage systems, such as NAS platforms, are inefficient, particularly when dealing with large files and duplicates, leading to increased network bandwidth usage, computing resource consumption, and prolonged user wait times.
Innovation Solution
Implementing a scan status data structure that stores file identifiers and malware scan results, allowing the system to bypass redundant scans for duplicate files by referencing the scan status of previously scanned files, thereby reducing the need for duplicate malware scans and enhancing AVS throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional malware scanning techniques are used to scan all files, then malware protection is maintained, but network bandwidth usage and computing resource consumption increase significantly
Solution Approach 1:
The system performs preliminary actions by scanning files only once and storing the scan status in a data structure. Subsequent scans reference the stored status instead of performing full scans again, preventing redundant scanning operations and reducing network bandwidth and computing resource consumption while maintaining malware protection.
Solution Approach 2:
The system creates a copy of the scan status information and stores it in a data structure. When a file needs to be scanned again, the system references this copied status information rather than performing a complete scan, thereby reducing the computational and network resources required while maintaining security.
2Reliability
If duplicate files are scanned separately, then malware detection is ensured, but user wait times increase due to redundant scanning
Solution Approach 1:
The system performs the scan action once for each unique file and stores the result. When duplicate files are accessed, the system references the pre-stored scan status, eliminating redundant scanning operations and significantly reducing user wait times while ensuring malware detection through the stored results.
Solution Approach 2:
The system creates and stores a copy of the scan status for each file. When duplicate files are encountered, the system references this copied status information, avoiding redundant scanning and reducing user wait times while maintaining reliable malware detection through the stored scan results.
3Productivity
If a scan status data structure is implemented, then redundant scans are avoided and throughput increases, but device complexity increases
Solution Approach 1:
The system segments the scan status information into a dedicated data structure that stores file identifiers and scan results separately. This segmentation allows the main scanning process to remain simple while the data structure handles the complexity of tracking and referencing scan statuses, thereby increasing throughput without proportionally increasing overall system complexity.

AI summary
Malware scan status determination for network-attached storage systems is provided herein. A data storage system as described herein can include a memory that stores computer executable components and a processor that executes computer executable components stored in the memory. The computer executable components can include a data creation component that creates a scan status data structure associated with a network-attached storage (NAS) device, the scan status data structure comprising respective records that indicate a file identifier and a malware scan status for respective files stored on the NAS device, and a data update component that updates a record in the scan status data structure corresponding to a target file stored on the NAS device in response to receiving a malware scan result for the target file.
