Practical Internet of Things Security - Second Edition

Install/update sensors

Sensors in the traditional IT sense may be host-based monitoring agents installed on enterprise computers (for example, ones that collect host logs for backend audit), or IDS/IPS-enabled network sensors. In the IoT, putting agents on the constrained edge things within a system is not straightforward, and in some cases may simply not be feasible.

That does not mean that you cannot instrument your IoT system, however. Let's examine an architectural fragment:

We can evaluate collected security-relevant data by considering an IoT architectural model of WSN endpoints transmitting data to a protocol gateway, then that gateway ...
