A trash can, a credit card, & a trip to the computer store

“A trash can, credit card, and a trip to the computer store” is how Bruce Schneier recently described the software update process (patch management) for networked consumer devices, aka Internet of Things devices. This category of devices already include home/small business routers and cable modems and is quickly growing to include home energy management devices, home health devices and systems, and a plethora of automation devices and systems.

I believe he is spot on. There may be a few people who consistently download, reprogram, and reconfigure their devices but I would estimate that it’s well under 1%.

The problem of software updates/patch management for Internet of Things devices, both consumer and enterprise, is a significant issue onĀ its own. The bigger issue, though, is that we largely tend to think we’re going to manage these updates in a traditional way such as Microsoft’s famous Patch Tuesday. That simply won’t happen with the raw number of Internet of Things devices as well as the variability of types of devices.

The work before us then is twofold: 1) Are there automated patch management solutions that can be developed to detect outdated software and update/patch the same for at least a subset of all of the devices on the network, and 2) Find a way to formally acknowledge and document the risk of thatĀ larger group of devices that remain forever unpatched.

Option 1 has a cost. Option 2 has a cost. I think it will turn out that wrapping our heads around Option 2, the risk, will prove to be more difficult than creating some automated patching solutions.
