 For software you developed yourself, scan the source code to produce the SBOM regardless of the delivery form. Even when you deliver an executable, a binary, or firmware, scan the source code that produced it, not the finished artifact. Scanning a finished binary directly yields no package manager metadata, so PURLs are omitted, vulnerability matching fails entirely, and the SBOM is rejected.

 자체 개발 소프트웨어라면 납품 형태와 무관하게 자기가 개발한 소스코드를 스캔해 SBOM을 만듭니다. 실행 파일이나 바이너리, 펌웨어로 납품하더라도 완성된 산출물이 아니라 그것을 만든 소스코드를 스캔합니다. 완성된 바이너리를 그대로 스캔하면 패키지 매니저 메타데이터가 없어 purl이 누락되고, 취약점 매칭이 전량 실패해 반려됩니다.
