Scenario 2: Here, we discuss a comprehensive scenario with a fine grained authorization policy as shown in Fig. 4.6. Sensor_1 is a light sensor that monitors light level of its surrounding environment and if light level is low (i.e., it is dark), then a message is published to turn on outdoor lights which are Light_1 and Light_2. As soon as the lights get turned on, home owner receives a text message notification about the state change of the lights. In this scenario, a more restrictive access control policy is defined for Sensor_1. The policy is based on Sensor_1 thing attributes specified as a Condition in the policy. Figure 4.6b shows the fine grained policy which includes two policy statements—first statement authorizes a client to connect to AWS IoT only if its client ID is Sensor_1, and second statement allows publish, subscribe, and receive operations on any resources if and only if the client requesting access has a thing attribute Belongs and its value is Home1. This policy employs thing attributes which represent the characteristics of IoT things/devices and allow to define more fine grained access control policy as shown in Fig. 4.6b.
