From 1d7a9debf241f9649a40ebc367204bac0a86a67e Mon Sep 17 00:00:00 2001 From: Maximilian Brune Date: Thu, 14 Apr 2022 14:54:16 +0200 Subject: Add SBOM (Software Bill of Materials) Generation Firmware is typically delivered as one large binary image that gets flashed. Since this final image consists of binaries and data from a vast number of different people and companies, it's hard to determine what all the small parts included in it are. The goal of the software bill of materials (SBOM) is to take a firmware image and make it easy to find out what it consists of and where those pieces came from. Basically, this answers the question, who supplied the code that's running on my system right now? For example, buyers of a system can use an SBOM to perform an automated vulnerability check or license analysis, both of which can be used to evaluate risk in a product. Furthermore, one can quickly check to see if the firmware is subject to a new vulnerability included in one of the software parts (with the specified version) of the firmware.
