Abstract: A software bill of materials (SBOM) and vulnerability management system (“system”) disclosed herein extracts software component-related identifiers for Internet of Things (IoT) devices using deep packet inspection. The system filters the identifiers by removing identifiers that match a blacklist of identifiers known to not correspond to software components. The system then populates SBOM fields using a database storing the filtered identifiers with a schema that is uniform across SBOM file formats and queries a vulnerability database with software components indicated in the filtered identifiers to identify vulnerabilities for each IoT device for security risk assessment.
