Episode 79 — Capture Key Asset Attributes: Identity, Location, Ports, Ownership, Vendor, and Function
This episode teaches which asset attributes matter most for OT security decisions and why capturing the right details prevents wasted effort during audits, patch planning, and incident response. You’ll learn how to establish identity with stable identifiers, including hostnames, serial numbers, MAC addresses, and controller-specific identifiers, while avoiding the trap of treating any single attribute as infallible in isolation. Location is covered as more than a building name, emphasizing cabinet and line context that helps teams perform walkdowns, coordinate access, and understand environmental risks that affect reliability. Ports and interfaces are addressed with a security mindset, including exposed serial, USB, maintenance ports, and network services that define both attack surface and troubleshooting pathways. Ownership, vendor, and function are framed as governance essentials, because the ability to patch, change, or isolate a device depends on who has authority, what support contracts require, and what the device actually does in the process.
