Afterwards, this section presents the evaluation of this IoTSRM2-based survey study and the 12 reviewed related works for each evaluation criterion. **E1: The research study is focused on determining the current state of IoT security risk management strategies in organizations**  
None of the reviewed related works focused on determining the current state of IoT security risk management strategies in organizations. However, the 12 reviewed related works addressed this issue to a certain extent by focusing on determining the current state of IoT security in organizations (i.e., [15; 32; 33; 35; 36; 38; 40]), of Industrial IoT (IIoT) security in organizations (i.e., [37; 39]), of IoT security for consumers (i.e., [31; 34]) and of third party IoT risk management in organizations (i.e., [19]). With respect to the seven reviewed related works that focused on determining the current state of IoT security in organizations, these related works focused their studies on understanding IoT security challenges and opportunities, threats, risks, capabilities and enablers, and investment priorities. Thus, first, Palo Alto Networks [15] evaluated the state of the IoT threat landscape by using data from real deployments. Second, Arm Limited [32] focused their study on understanding the IoT security challenges and opportunities from the surveyed organizations. Third, [PERSON] and [PERSON] [33] investigated the attitudes and perceptions among interviewed industry actors on IoT security in critical societal services. Fourth, Forescout Technologies [35] provided the state of enterprise IoT network security of some of their customer deployments within and across industry verticals by looking at enterprise network threat and risk exposure. Then, Gemalto [36] provided the IoT security state in surveyed organizations by looking at the IoT security capabilities of and the use of blockchain technology to secure IoT data, services, and devices in surveyed organizations.
