Answer yes if your organisation maintains an inventory of software, firmware, and other dependencies (e.g. an SBOM or equivalent) for the OT systems, products, or services you provide. Describe how dependencies are identified, maintained, and reviewed in the notes. Upload supporting documentation as evidence.
OT systems often run for many years with firmware and embedded software that isn't updated as frequently as standard IT, making it important to know exactly what's running so that vulnerabilities can be tracked as they're disclosed. This control checks for a maintained inventory of software and firmware dependencies, such as an SBOM, for the OT systems, products or services you provide.
Maintain an inventory of software, firmware, and other dependencies for your OT systems, an SBOM or equivalent, and review and update it as dependencies change.
