IoT in the Smart Home: Challenges and Solution

The Internet of Things was sweeping the world only five years ago, and people were speculating about a future in which 20 billion IoT devices would be online by 2020, according to the Vision 2020 initiative. Now, in 2019, we are getting closer to that reality, and the Internet of Things (IoT) is rapidly spreading into the atmosphere in a variety of fields. All of the major technology companies are now taking a look at the Internet of Things, which has a wide range of applications in smart homes, vehicular networks, healthcare, big data, and other areas.

According to a recent survey conducted in the United States, more than half of the population is willing to spend $500 on smart home devices and appliances. The Internet of Things is most commonly used in smart homes to automate a variety of household tasks. These smart home devices are transforming televisions, refrigerators, and doors, which makes life easier for the residents who live in them. This also enables businesses to provide their customers with Internet of Things devices and services.

Aspects of the smart home that are in danger IoT

While the Internet of Things (IoT) promises a great deal of convenience for end-users, as evidenced by smart homes, security and privacy concerns are growing as a result of the lack of progress in this area, particularly when it comes to security by design. As a result of the WannaCry incident, it is clear that Internet of Things devices provide an open window for hackers to launch widespread attacks and cause widespread damage. Many commercially available devices, such as the Belkin WeMo motion sensor, the Nest Smoke Alarms, and the Withings Smart Body Analyzer, lack security features that would protect them from malicious users. Security researchers conducted a thorough analysis of the devices and discovered that they were vulnerable to a variety of security threats. These devices communicate in plain text, which makes them vulnerable to being intercepted by a malicious entity. In addition to security concerns, privacy concerns have also been raised. As discovered by researchers in the widely used motion sensors, these sensors, which are used in large numbers, contain a great deal of personal information that an attacker can use to track a victim. These issues will continue to be present and will require continued attention and awareness on the part of technology innovators as well as consumers.


There is no single plug that you can turn on to secure your Internet of Things devices. However, there are some solutions that consumers can use to increase their security to the greatest extent possible. On the other hand, in order to improve device security, the research community, the technical community, and the business community must collaborate.

Consumers should follow these three common steps to keep their IoT devices in their homes safe.

1. Make certain that the devices are secured with a strong password. 2. Learn about the security features that your devices offer and how to activate them.

2. Double-check to see that the devices are set to receive automatic updates. Consumers frequently turn this feature off in order to make their device operate more quickly.

3. Your home router serves as the primary gateway to the insecure internet from the outside world. Check that your Wi-Fi settings, encryption settings, and non-default passwords are all in proper working order.

Long-term solutions that are novel

In the long run, emerging technologies have the potential to significantly improve the security and privacy of Internet of Things devices. Various studies are being conducted to determine whether SDN can be used to provide security as a service for smart home Internet of Things devices. Another approach is to use a blockchain-based architecture to improve the privacy and security of IoT devices by deploying a blockchain at a low scale and then scaling it up.

The Internet of Things (IoT) has a wide range of applications in next-generation evolution. As a result of the protective measures built into the technology, it will be able to meet the future challenges of security and privacy in the future.
