Browser Extension for Real-Time Web Application Vulnerability Detection

The patent introduces a browser extension as an intermediary component that monitors HTTP requests and executes security vulnerability tests. This intermediary layer sits between the user's browser and the web application server, enabling real-time security monitoring without requiring modifications to the core application infrastructure. The extension captures request data, analyzes it for vulnerabilities, and reports findings, thereby resolving the complexity issue by distributing the monitoring function to a specialized intermediate component rather than embedding it throughout the entire system.

The security vulnerability assessment system is segmented into distinct functional modules: HTTP request monitoring, request analysis, vulnerability testing, and result reporting. Each module operates independently and can be implemented separately, allowing for easier maintenance and reduced overall system complexity. The browser extension itself is segmented into specific functions for capturing network traffic, parsing HTTP requests, identifying testable elements, and communicating with the vulnerability testing engine.

The system performs partial vulnerability testing by focusing only on specific testable elements identified within HTTP requests rather than analyzing every possible aspect of web traffic. The browser extension selectively monitors only the relevant portions of HTTP requests that contain potential vulnerability vectors, such as form submissions and parameter transmissions. This selective approach enables real-time detection while reducing unnecessary computational overhead by ignoring non-critical traffic patterns.

The vulnerability assessment operates in periodic cycles, monitoring HTTP requests at key moments during user interaction rather than continuously analyzing all traffic without interruption. The system activates monitoring when forms are submitted or when specific vulnerable patterns are detected, allowing for efficient resource utilization. This periodic action mode enables the system to maintain detection speed for critical events while conserving computational resources during normal browsing operations.
