Weblink Content Scanning With Sandbox Isolation for Real-Time Threat Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cyber security systems lack the capability for real-time analysis and monitoring of potentially malicious content accessed through weblinks in electronic communications, leading to potential unauthorized access and network harm.
Innovation Solution
A weblink content scanning system that isolates and scans content in a sandbox environment, generates hashes, and compares them to a data store for categorization as safe, malicious, or potentially malicious, modifying or blocking communications as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cyber security systems scan weblink content to identify malicious links, then security categorization can be performed, but real-time analysis and monitoring capability is lacking
Solution Approach 1:
The system performs preliminary scanning and hashing of weblink content when links are first encountered or added to the data store, preparing security categorizations in advance. This preliminary action enables rapid real-time comparison and detection without performing full analysis during critical monitoring moments, thus resolving the contradiction between detection accuracy and real-time capability.
Solution Approach 2:
The system changes the parameter of content representation from full content storage to hash value storage. By converting content to hash parameters, the system enables fast real-time comparison operations while maintaining the ability to accurately detect malicious content through hash matching, thus achieving both real-time analysis and reliable security detection.
2Measurement precision
If weblink content is accessed and analyzed in detail, then malicious content can be identified, but network security may be compromised during the analysis process
Solution Approach 1:
The system introduces an intermediary hashing mechanism between the original content and the analysis process. By converting content to hash values, the system enables precise malicious content detection through hash comparison while avoiding the security risks associated with accessing and analyzing original content, thus resolving the contradiction between detection accuracy and network security.
Solution Approach 2:
The system creates a copy of the content in the form of a hash value rather than working with the original content. This copying approach enables accurate malicious content identification through hash matching while eliminating the security vulnerabilities that would arise from directly accessing and analyzing the original potentially malicious content.
3Reliability
If feedback from user groups is collected and analyzed, then security categorization can be improved, but real-time response capability is reduced
Solution Approach 1:
The system performs preliminary hash computation and security categorization when content is first encountered, storing these results in advance. This preliminary action eliminates the need for real-time user feedback collection and analysis, as the security categorization is already determined through hash matching, thus resolving the contradiction between categorization accuracy and real-time response capability.

AI summary
An illustrative computing system for a weblink content scanning system scans an electronic message for the presence of one or more weblinks. The computing system accesses, in a sandbox computing environment, content linked to the one or more weblinks. The computing system generates a hash of the accessed content and/or content linked to weblinks accessible via the accessed content. The computing system scans the content accessed via the one or more weblinks for a presence of malicious content and categorizes the scanned content accessed via the one or more weblinks (e.g., safe, malicious, and the like), associates the categorization with each corresponding hash, and saves such information to a data store for future analysis. Based on a result of this analysis, the computing system allows delivery of the original electronic message or generates a modified electronic message for delivery to a recipient device.
