Web Thumbnail System for Anomaly Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprise networks face challenges in managing and identifying web-enabled systems, rogue websites, defaced websites, and unsecured content within their internal and external networks, making it difficult to maintain security and detect anomalies.
Innovation Solution
An automated web thumbnail system that captures and compares snapshots of web pages over time, enabling visual review and detection of anomalies, such as missing links, unsecured websites, and malware infections, while identifying approved and unapproved web services and content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated tools are used to discover and monitor web servers, then website security monitoring capability is improved, but system complexity increases
Solution Approach 1:
The system creates visual copies (thumbnails) of web pages instead of analyzing the full complex content. By capturing thumbnail images of web pages and comparing these visual representations across time periods, the system simplifies the monitoring process while maintaining security detection capability. This allows automated security monitoring without requiring complex analysis of complete web page content.
2Measurement precision
If visual review of web pages is enabled, then detection precision of anomalous content is improved, but time consumption increases
Solution Approach 1:
The system segments web page content into thumbnail representations, allowing reviewers to quickly scan visual summaries instead of examining complete web pages. By comparing thumbnails across different time periods, the system enables rapid identification of changes while maintaining detection precision for anomalous content.
Solution Approach 2:
The system captures and displays only the essential visual elements of web pages in thumbnail form, rather than requiring review of complete page content. This partial representation provides sufficient information for detecting anomalies and unauthorized changes while dramatically reducing the time required for security review.
3Reliability
If snapshots are captured and compared over time, then detection of unauthorized changes is improved, but data storage requirements increase
Solution Approach 1:
Instead of storing complete web page content for historical comparison, the system creates and stores simplified thumbnail copies. These visual representations capture the essential appearance of web pages at different times, enabling detection of unauthorized changes while requiring minimal storage space compared to storing full page content.
Data Source
AI summary
A method for locating and monitoring websites is provided that includes finding websites and contained hyperlinks, downloading a first snapshot of a web page taken at a first time, and downloading a second snapshot of the web page taken at a second time later than the first time. The method also includes enabling a comparison of the first snapshot and the second snapshot. A system for monitoring websites is provided. The system includes means for enabling a comparison of the first snapshot and the second snapshot visually or through the use of content data from that web site. A computer-readable recording medium having recorded thereon an executable program is provided. The program when executed causes a processor to perform a method for monitoring websites.
