My digital camera uses exif to convey a vast amount of contextual information and imprint it on each photo: date, time, the camera, shutter, aperture, flash. I have GPS in the camera so it can tell the location, elevation. The exif protocol also allows for vendor specific information and is extensible and customizable.
Unless and until we have an 'exif' for IoT its going to be lame and useless.
What is plugged in to that socket? A fan, a PC, a refrigerator, a charger for your cell phone? What's the rating of the device? How is it used? What functions other than on/off can be controlled?
Lame lame lame lame.
So I need to compile a list of ALL assets, information or otherwise,
That leads to tables and chairs and powerbars.
OK so you can't work without those, but that's not what I meant.
Physical assets are only relevant in so far as they part of information processing. You should not start from those, you should start from the information and look at how the business processes make use of it. Don't confuse you DR/BC plan with your core ISMS statements. ISO Standard 22301 addresses that.
This is, ultimately, about the business processes.
