Internet of things (IoT) is referred to as smart devices connected to the internet. A smart device is an electronic device, which may connect to other devices or are part of a network such as Wi-Fi. The increase of IoT devices has helped with advancing technology in many areas of society. Application of IoT in 5G/B5G devices has provided many benefits such as providing new ideas that can become projects for tech companies, generating big data (large volume of data which can be used to reveal trends, patterns and associations) and providing various ways of communicating. This has also had an impact on how companies improve their business with the use of advanced technology. However, the rapid growth of IoT has introduced a new platform for cybercriminals to attack. There has been published security measures on IoT to help deal with such risks and vulnerabilities. This survey paper will explore IoT in relation to smart homes, smart cities, wearables and connected cars. The benefits, risks and vulnerabilities will be discussed that comes along with using such devices connected to the internet.
