Discovering And Accessing Software Bills of Materials
draft-ietf-opsawg-sbom-access-00
Abstract
Software bills of materials (SBOMs) are formal descriptions of what
pieces of software are included in a product. This memo specifies a
different means for SBOMs to be retrieved.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."

1. Introduction
Software bills of material (SBOMs) are descriptions of what software,
including versioning and dependencies, a device contains. There are
different SBOM formats such as Software Package Data Exchange [SPDX],
Software Identity Tags [SWID], or CycloneDX[CycloneDX12].
This memo specifies means by which SBOMs can be advertised and
retrieved.
The mechanisms specified in this document are meant to satisfy
several use cases:
o An application-layer management system retrieving an SBOM in order
to evaluate the posture of an application server of some form.
These application servers may themselves be containers or
hypervisors. Discovery of the topology of a server is beyond the
scope of this memo.
o A network-layer management system retrieving an SBOM from an IoT
device as part of its ongoing lifecycle. Such devices may or may
not have interfaces available to query SBOM information.
To satisfy these two key use cases, SBOMs may be found in one of
three ways:
