A Study on IoT layered Attacks and Countermeasures
Smrithi Surendran, V Sarasvathi · 2022
The Internet of Things is the next era of communication. There are many types of IoT devices which are now used widely in different fields such as, home automation, agriculture, in factories or industries for manufacturing, transportation, in healthcare for patient monitoring etc. Types of IoT devices include Infrared sensors, laser scanner, home automation devices, RFID (Radio Frequency Identification Devices), location tracking sensors like GPS and gas-inductors. The current and future IoT technology is relatively assuring to increase all the facilities like comfort, efficiency, and automation for the users. As IoT devices become more and more advanced, they also gain the ability to collect more information and store in the cloud. There are some reasons why security becomes an important feature in IoT. Unauthorized devices weaken the entire network, IoT devices transmit data across multiple sectors, one weak link opens the entire network to cyber-attacks and other attacks and sensitive data theft is hard to notice in some devices as they continue storing larger amounts of data. In this regard, it is imperative to add security features in the IoT model to achieve a secure platform or environment. This paper discusses, few security-related challenges in different layers in IoT and sources of threat in the different layers pertaining to the model with countermeasures for few attacks.
