Protecting Your Smart Home:

A Guide to Securing Your IoT Devices

3 min readMar 27, 2023

The Internet of Things (IoT) is a term used to describe the growing network of devices connected to the internet, from smart home appliances to industrial equipment. While IoT devices have the potential to make our lives easier and more efficient, they also pose a significant security risk.

In this blog, we will discuss how common IoT devices are, how vulnerable they can be, and what people can do to make them more secure.

How common are IoT devices?

IoT devices are becoming increasingly common in both homes and businesses. Gartner’s report projected that the number of IoT devices would reach 25 billion by 2021.

Some common examples of IoT devices include: Smart home devices, such as thermostats, security cameras, and voice assistants, Wearables, like fitness trackers and smartwatches. Industrial IoT devices, such as sensors and controllers used in manufacturing and logistics. While these devices offer many benefits, they also come with their own set of security risks.

How vulnerable are IoT devices?

IoT devices are often designed with convenience and usability in mind, rather than security. Many IoT devices have weak or default passwords, are not updated regularly, and lack proper encryption. This makes them vulnerable to a range of attacks, including:

Malware infections: IoT devices can be infected with malware, which can be used to launch attacks on other devices or networks.
Botnet attacks: IoT devices can be recruited into botnets, which can be used to launch large-scale attacks, such as distributed denial-of-service (DDoS) attacks.
Data breaches: IoT devices can store sensitive data, such as personal information and financial data, which can be stolen in a data breach.

How can a common person make IoT devices more secure?

While IoT device manufacturers have a responsibility to design devices with security in mind, there are also steps that people can take to make their devices more secure. Here are some tips:

Change default passwords: Many IoT devices come with default usernames and passwords, which are easy for attackers to guess. Change these passwords to something strong and unique.
Update software regularly: IoT devices should be updated regularly to patch security vulnerabilities and improve functionality.
Use strong encryption: Make sure that any sensitive data transmitted by IoT devices is encrypted to protect it from interception by attackers.
Disable unnecessary features: Some IoT devices may have features that are not needed and can pose security risks. Disable these features if possible.
Use a separate network: Consider using a separate network for IoT devices to isolate them from other devices on your home or business network. This can help contain any potential security breaches.


IoT devices are becoming more common and present a significant security risk if not properly secured. By taking steps to improve security, such as changing default passwords, updating software regularly, and using strong encryption, common people can help make their IoT devices more secure and reduce the risk of security breaches. As the IoT continues to grow, it is important that we all take responsibility for securing our devices and networks.
