Security Threats in IOT and Their Prevention

IoT is making our day-to-day life easy by connecting us to the web which in fact enhance the standard of living. IOT plays a crucial part in our daily life ranging from small devices to massive devices. However, IoT is also quite susceptible to several threats. Due to the increased likelihood and ease with which malicious individuals can target IoT devices in order to satisfy their evil ambitions, IoT safety and confidentiality protection are of the prime importance. User’s security gets compromised once an IoT layer is breached. Hackers might simply gain access through a compromised node. Moreover, viruses, hackers and malicious software may compromise information and data integrity, which will expose the entire IoT environment to information anxiety. Like the OSI layers, IoT layers are the best approach for understanding. This chapter describes different kinds of security issues pertaining each layer in IoT and discusses the means and methods to deal with these security threats.
