Episode 80 — Maintain Software Inventory and Map to Hardware: Visibility That Enables Decisions

 This episode explains why software inventory in OT must be mapped to hardware reality, because risks often live in firmware versions, installed packages, configuration sets, and vendor toolchains that do not show up in a simple device list. You’ll learn what “software inventory” includes in OT contexts, such as operating systems, controller firmware, HMI applications, engineering suites, drivers, and middleware components, and why version visibility is essential for vulnerability response that does not break support agreements. Mapping software to hardware is taught as a dependency practice, connecting what is installed to where it runs, who owns it, what it supports, and what must be coordinated if changes are needed, especially when a single workstation supports multiple lines or sites. We also cover best practices for keeping software inventories current through change triggers, vendor advisories, periodic validation, and evidence capture that supports audits and incident forensics. Troubleshooting considerations focus on avoiding inaccurate assumptions, such as thinking all devices are on the same firmware because a project was “standardized,” and instead using validated records and controlled baselines to make safe, defensible decisions.
