Internet of Things (Io T) security deals with safeguarding the devices and communications of Io T systems, by implementing protective measures and avoiding procedures which can lead to intrusions and attacks. However, security was never the prime focus during the development of the Io T, hence vendors have sold Io T solutions without thorough preventive measures. The idea of incorporating networking appliances in Io T systems is relatively new, and hence Io T security has not always been considered in the product design. To improve security, an Io T device that needs to be directly accessible over the Internet should be segmented into its own network, and have general network access restricted. The network segment should be monitored to identify potential anomalous traffic, and action should be taken if a problem arises. This has generated an altogether new area of research, which seeks possible solutions for securing the devices, and communication amongst them.
