Dependency CPE Scoring for Precise Software Vulnerability Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting vulnerabilities in software projects using Structured Query Language (SQL) queries require significant manual effort and are prone to missing vulnerabilities, leading to potential security risks due to high false-positive rates and the need for substantial manual intervention.
Innovation Solution
A method involving a dependency file parser to generate a dependency common platform enumeration (CPE) and utilize a vulnerability database to create a condensed dataset of vulnerability CPEs, with a confidence score evaluation and machine learning model to filter results, reducing manual effort and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SQL queries are used for Software Composition_analysis to map vulnerabilities to software components, then vulnerability detection can be performed, but the process requires significant manual work and is time-consuming
Solution Approach 1:
The system automatically generates and executes SQL queries based on dependency information from package.json files, eliminating the need for manual query creation. The vulnerability matching process is fully automated, comparing dependency attributes with vulnerability database entries without human intervention, thus reducing both time consumption and manual effort while maintaining detection accuracy.
Solution Approach 2:
The system pre-processes dependency information by extracting and structuring data from package.json files before vulnerability matching occurs. Dependency attributes are organized and stored in a standardized format in advance, enabling rapid automated querying and comparison with vulnerability databases, thereby reducing the time required for the actual vulnerability detection process.
2Measurement precision
If manual SQL queries are implemented to handle edge-cases and reduce false-positives, then detection precision may improve, but the device complexity and difficulty of operation increase
Solution Approach 1:
The system uses a universal automated query generation mechanism that handles all edge-cases through standardized attribute comparison logic. Instead of requiring multiple specialized SQL queries for different scenarios, a single automated process adapts to various dependency types and vulnerability patterns, reducing system complexity while maintaining precision through consistent application of matching rules.
Solution Approach 2:
The system replaces manual mechanical query construction with an automated computational process. The automated system generates and executes SQL queries based on dependency attributes, eliminating the need for manual query writing and adjustment. This substitution reduces operational complexity and makes the system easier to operate while maintaining or improving detection precision through systematic attribute matching.
3Reliability
If comprehensive vulnerability monitoring is performed to reduce security risks, then reliability improves, but productivity decreases due to substantial man hours required
Solution Approach 1:
The system performs comprehensive vulnerability monitoring automatically without requiring manual intervention. The automated process extracts dependency information, generates queries, matches vulnerabilities, and produces results independently, eliminating the need for substantial man hours while maintaining comprehensive security coverage. This self-service approach preserves reliability through thorough monitoring while dramatically improving productivity.
Solution Approach 2:
The system replaces manual vulnerability monitoring processes with an automated computational system. The automated generation and execution of SQL queries, along with automatic vulnerability matching and reporting, substitutes human labor with machine processing. This substitution maintains comprehensive security monitoring for reliability while reducing the time and effort required, thereby improving overall productivity.
