SE Radio 668: Steve Summers on Securing Test and Measurement Equipment

·55 min·5 clips

A virus in a photo frame tester spread malware to homes worldwide, showing how test systems can become global attack vectors.

Security starts with measurement work. Sam Taggart opens by asking Steve Summers to define test and measurement equipment, then the conversation moves quickly into networked systems and the security mess they bring with them. Summers keeps it close to the work engineers already do: testing products, linking systems, sharing data, and trying to keep specialized gear understandable to the people who own the network. That is where the friction shows up. IT owns the network, but test engineers often run equipment and protocols IT may not know well. For a while, the answer was isolation. Test teams built internal networks, treated them as air gapped, and assumed that limited outside access made security less urgent. Summers makes the case that this comfort is getting old. AI tools, model access, and reporting back into corporate systems all pull those test networks outward. Once that happens, the test station is no longer someone else's little island. It is part of the attack surface. The episode works best when it gets specific. Devices have locations. Systems have connections. Visibility either exists or it does not. Modbus is the clean example: if a device speaks Modbus on a regular network, Wireshark can see that traffic. By the end, the topic feels less like a niche security specialty and more like network security finally meeting test system reality.

As heard by us

A clear look at how test and measurement systems become part of the security conversation.

Steve Summers and Sam Taggart start from a field that sounds narrow and show why it no longer stays that way. The episode moves from test stations as isolated gear to the messier reality of shared data, AI tools, and corporate connectivity, which pulls test systems into IT…
