The Internet of Things (IoT) refers to the growing network of devices that are connected to the internet. These devices can range from everyday household items (like a fridge!) to sophisticated industrial tools. As more devices connect to the internet, new security risks emerge.

Let’s look at some new ways to keep your IoT devices safe.

What are the security risks for IoT devices?

IoT devices are vulnerable to many types of threats. Some of the common risks include:

Poor Passwords

Many IoT devices come with default passwords, which users often fail to change. This makes them easy targets for hackers. Using weak or repeated passwords across multiple devices further increases the risk.

Outdated Software

Outdated software can contain vulnerabilities and bugs that cybercriminals exploit. Many IoT devices do not receive regular updates, leaving them unpatched and vulnerable to attacks.

Lack of Encryption

Some IoT devices transmit data without any form of encryption. This exposes sensitive information, allowing hackers to intercept and read the data easily.

How to enhance security in IoT devices?

Improving the security of IoT devices is crucial for protecting personal and business data. Here are some effective strategies:

Use Strong Passwords

Always change the default password provided with the device. Choose long and complex passwords, and avoid using the same password across multiple devices.

Keep Software Updated

Regularly check for software updates for your IoT devices. These updates often include security patches that fix vulnerabilities. Some devices can update automatically – enable this feature if available.

Enable Data Encryption

Where possible, activate data encryption on your IoT devices. This ensures that any transmitted data is scrambled and cannot be read by unauthorised users.

What New Technologies Help with IoT Security?

Advancements in technology are enhancing IoT security. The most notable innovations include:

Artificial Intelligence (AI)

AI can monitor devices for unusual behaviour and detect potential security threats. It learns and adapts over time, improving its ability to identify risks.

Blockchain

Blockchain technology can provide tamper-proof data records. It secures a complete history of actions performed by or on a device, ensuring data integrity.

Edge Computing

By processing data closer to the device itself, edge computing reduces the risk of data interception during transmission.

How Can Companies Improve the Security of IoT?

Businesses must take proactive steps to secure their IoT networks:

Develop a Security Policy

Implement comprehensive security policies for the use of IoT devices. Ensure that all employees receive proper training on these security guidelines.

Implement Network Segmentation

Separate IoT devices from other networks within the organisation. This limits the potential damage in case of a security breach.

What can Consumers do to Protect their IoT Devices?

Everyday users can also enhance the security of their IoT devices by:

Do your Homework Before Buying

Choose IoT devices from reputable companies known for prioritising security and providing regular software updates.

Secure your Home Network

Use a strong Wi-Fi password and enable network encryption to safeguard connected devices.

Limit Digital Connections

Only connect essential devices to your network and disconnect them when not in use to reduce security risks.

How will IoT Security Evolve in the Future?

IoT security is constantly evolving. Key trends to watch include:

Stricter Regulations

Governments are likely to introduce stricter regulations to enhance IoT security standards, compelling manufacturers to produce safer devices.

Built-in Security Features

Future IoT devices may come with improved security features out of the box, such as automatic data encryption.

Increased User Control

Manufacturers are likely to provide users with more control over their devices' security settings, including user-friendly security dashboards.
