IoT network interconnects the heterogeneous devices having sensors with diverse functionalities, which are established the connection with either a private or a public network. Several widely used IoT application areas include smart agriculture, smart home, smart city, smart energy, smart healthcare, connected building, connected industry, connected car, and logistics. IoT devices generate and exchange a vast amount of safety-critical data and also, privacy-sensitive data, which provides opportunities for cyber attacks in the IoT environment. Due to the different characteristics and data types of IoT applications, designing the adaptive forensics methodology is significant for the corresponding smart applications.
