The Internet of Things: Cyber Security Implications

Posted on: 25th July 2023

The Internet of Things (IoT) has rapidly become part of our everyday lives, from smart homes to connected cars. But with this increased connectivity and the opportunities it brings comes increased security risks.

In this piece our Chief Technology Officer, Andy Hunter, discusses the cyber security implications of IoT and offers some tips on how to protect your business.


The Threats

IoT poses several security risks, including:

  • Data breaches: IoT devices often collect and store sensitive data, such as personal information or financial data. If a hacker gains access to this data, it could be used for identity theft or other malicious purposes.
  • Malware attacks: IoT devices are vulnerable to malware attacks. With access to an IoT device, hackers can use it to spread malware to other devices or to launch denial-of-service attacks.
  • Physical damage: IoT devices can also be used to cause physical damage. For example, a hacker could use an IoT-connected thermostat to overheat a building or use an IoT-connected car to cause an accident.


How to Protect Your Business

There are a number of steps you can take to protect your business from IoT security threats, including:

  • Keep your devices up to date: IoT devices often have security vulnerabilities that can be exploited by hackers. Make sure you keep your devices up to date with the latest security patches.
  • Use strong passwords: Use strong, complex passwords for all your IoT devices. Avoid using default passwords or passwords that are easy to guess.
  • Enable multi-factor authentication (MFA): this adds an extra layer of security to your IoT devices. When you enable two-factor authentication, you will be asked to enter a code from your phone, in addition to your password, when you log in to your device.
  • Be careful what you connect to your network: Only connect trusted IoT devices to your network. Avoid connecting IoT devices that you have not bought from a reputable source.
  • Implement segmentation on your network, to make sure devices are only allowed to communicate as required.
  • Monitor your network for suspicious activity: Use a network monitoring tool to keep an eye on your network for anything that looks out of the ordinary. This will help you to identify security threats early, and respond to them quickly.


There’s no doubt that IoT is a powerful technology that is already improving our lives in many ways. But it’s also important to be aware of the security risks associated with IoT devices. By being cautious and taking the necessary precautions, you can help to protect your business from these risks.
