A Review on Security and Privacy Issues in IoT Devices

Abstract

In everyday lives, the Internet of Things (IoT) has been used in everywhere. It is used for the monitoring and documentation of
environmental improvements, fire safety and even other useful roles in our homes, hospitals and the outdoors. IoT-enabled
devices that are linked to the internet transmit and receive a large amount of essential data over the network. This provides an
opportunity for attackers to infiltrate IoT networks and obtain sensitive data. However, the risk of a loss of privacy and security
could outweigh any of these benefits. Many tests have been carried out in order to solve these concerns and find a safer way to
minimize or remove the effect of IoT technologies on privacy and security practices in order to protect them. The issue with IoT
devices is that they have small output modules, making it impossible to adapt current protection methods to them. This
constraint necessitates the presentation of lightweight algorithms that enable IoT devices. In this article, investigated the context
and identify different safety, protection, and approaches for securing components of IoT-based ecosystems and systems, as well
as evolving security solutions. In addition, several proposed algorithms and authentication methods in IoT were discussed in
order to avoid various types of attacks while keeping the limitations of the IoT framework in mind. Also discuss some hardware
security in IoT devices.
