Key Features:
- Syft Integration: Seamless integration with Syft CLI tool
- Comprehensive SBOM Models: Full SPDX/CycloneDX compatible data structures
- Advanced Analysis: Vulnerability detection, license compliance, risk scoring
- Multiple Report Formats: Console, Markdown, JSON reporting
- Spring Boot Integration: REST API and service layer
- Caching: Performance optimization for repeated analysis
- CI/CD Ready: Validation and integration for pipelines
- Extensible: Easy to extend with additional analyzers and reporters
This implementation provides a complete SBOM generation and analysis system that can be integrated into development workflows, CI/CD pipelines, and security scanning processes.
