Software Version Identification via Reference Library Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying the versions of software components on a computer system is challenging due to the lack of standardized formats and naming conventions, which complicates vulnerability assessment and compliance with licensing requirements.
Innovation Solution
A system that scans target files using a reference library to identify software components, determines their versions, and associates vulnerabilities and licensing schemes, employing file scanners, version detectors, vulnerability modules, and license modules to produce a comprehensive report.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a reference library with source code fragments is used to identify software component versions, then version identification accuracy is improved, but the complexity of the system increases due to multiple modules and databases
Solution Approach 1:
The system is divided into distinct functional modules: a file scanner module that reads target files, a version detector module that identifies versions using reference libraries, a vulnerability module that assesses security issues, and a license module that checks compliance. Each module performs a specific function, making the overall complex task manageable and maintainable while achieving accurate version identification.
Solution Approach 2:
A reference library serves as an intermediary database containing source code fragments and version information from multiple software components. This reference library acts as a mediator between the target files being scanned and the version detection process, enabling accurate identification without requiring direct integration with each software component's internal versioning system.
2Reliability
If comprehensive scanning of target files is performed to identify all software components, then completeness of vulnerability assessment is improved, but the time required for scanning increases
Solution Approach 1:
The reference library is pre-populated with source code fragments, version information, vulnerability data, and license information for numerous software components before the scanning process begins. This preliminary preparation allows the scanner to quickly match patterns in target files against known components without performing complex analysis during the actual scan, thus maintaining completeness while reducing scanning time.
3Manufacturing precision
If multiple databases (reference library, vulnerabilities database, licensing database) are maintained to provide comprehensive information, then the quality of security and compliance reporting is improved, but the complexity of data management increases
Solution Approach 1:
The system combines multiple specialized databases (reference library with version information, vulnerabilities database with security data, and licensing database with compliance information) into a unified scanning framework. The automated report generation module integrates data from all three databases to produce a single comprehensive report, managing the complexity of multiple data sources through a coordinated query and reporting system.
4Productivity
If automated report generation is implemented to provide comprehensive vulnerability and license information, then productivity in security assessment is improved, but the complexity of the system increases
Solution Approach 1:
The automated report generation module performs self-service by automatically querying the reference library, vulnerabilities database, and licensing database, then compiling and formatting the results into a comprehensive security and compliance report without requiring manual intervention. This automation significantly improves productivity in security assessment while the modular design keeps the added complexity manageable.
Data Source
AI summary
Target files in a search space are scanned to identify which versions of software components are present in the search space. A reference library is populated with indicia such as source code fragments of known versions of software components. A file scanner reads file data used to identify matches between the reference library content and target files, and a version detector determines which match candidates represent unique component versions. Once a component version is identified, a vulnerability module determines based on data in a vulnerabilities database what vulnerabilities are associated with the identified version, and a license module identifies which if any licensing schemes are applicable to the identified version. In one embodiment a report is automatically produced providing an indication of all matched files, their versions, vulnerabilities, and licensing schemes.
