Its no secret that there are significant concerns with Internet of Things (IoT) security. Late last year, for example, attackers exploited a vulnerability in a brand of IoT cameras to launch a DDoS attack on the website of security expert Brian Krebs. The following month the GSM Association (GSMA) released its IoT Security Guidelines.

However, several OS types, mainly for embedded and IoT devices, are unmanaged or arent suitable to run an agent. There exist several protocols, from different network layers that can be used for OS fingerprinting. Figure 1 displays these protocols, based on the Open Systems Interconnection (OSI) model.
