## 4 Related Work  
A sizeable number of academic and industry research studies has been published on IoT security [14]. However, at the time of writing, no research study was found to exclusively focus on determining the current state of IoT security risk management strategies in organizations. Hence, given there are numerous research studies in the literature relevant to IoT security, this section encompasses the related work to our IoTSRM2-related survey study and covers the related works that meet the following three selection criteria and one condition:  
* **Selection criterion 1:** The related work is available in English;
* **Selection criterion 2:** The related work is focused on determining the current state of IoT security risk management strategy in organizations at least to a certain extent;
* **Selection criterion 3:** The related work employs an interview-, survey-, or experiment-based research method;
* **Condition 1:** The related works are research studies from both academia and industry. Thus, Table 9 lists the 12 selected related works for our evaluation, and it outlines the following details: the current row number (i.e., \"No.\"), the author/publisher of the related research study (i.e., \"Author/publisher\"), the title of the research work (i.e., \"Title\"), and the corresponding reference (i.e., \"Reference\"). Then, this section covers the analysis of the 12 selected related works. Thus, with respect to the analysis of the literature related to our IoTSRM2-based survey study, Table 10 shows the IoTSRM2-based survey study together with the 12 reviewed related works mapped against the proposed evaluation criteria and the extent of applicability to each evaluation criterion. With respect to the proposed evaluation criteria, seven evaluation criteria were formulated based on our proposed methodology for determining the current state of IoT security risk management strategies in the surveyed organizations relative to the IoTSRM2 (see Section 2.2). Moreover, with respect to the extent of applicability, three types of applicability were considered relevant to indicate differences and/or similarities between this IoTSRM2-based survey study and the in-scope research works for this evaluation. \begin{table}
