The risks of smart devices: How to stay safe.

The unnecessary internet connection: Why your smart devices should keep to themselves

In today’s world of interconnected everything, it’s easy to get caught up in the excitement of smart devices. From refrigerators to thermostats, it seems like every appliance is now online. But is this really necessary? Should your fridge, stove, microwave, HVAC, and fans be connected to the internet? The answer is a resounding no.

Most new devices come with internet connectivity built-in, often enabled by default, with no option to turn it off. This eliminates choice and raises important questions about safety and security. Why do these devices need to be online? What benefits do they provide, and at what cost?

The truth is, many smart devices don’t require internet access to function. Your refrigerator doesn’t need to browse the web to keep your food cold. Your stove doesn’t need to connect to the internet to cook your meals. So, why are they connected? The answer lies in the world of data collection and marketing.

Companies are eager to collect data on your habits and preferences. By connecting your devices to the internet, they can gather information on your daily routines, from what you eat to how you heat your home. This data is then used to target you with advertisements and promotions. But at what cost?

The risks associated with connected devices are real. Hackers can exploit vulnerabilities in these devices to gain access to your home network, putting your personal data and security at risk. Malicious actors can also use these devices as entry points for larger-scale cyber-attacks.

So, what can you do to protect yourself? The solution is simple: create a separate network for your smart devices or restrict their internet access. By doing so, you can prevent these devices from communicating with the outside world while still allowing them to function locally.

Setting up a private network for smart devices

Setting up a private network for your smart devices is a straightforward process. Here’s a step-by-step guide:

1. Create a guest network: Most routers allow you to create a guest network. This network will be separate from your main network, and devices connected to it will not be able to access your main network.

2. Connect your smart devices to the guest network: Move your smart devices to the guest network. This will prevent them from accessing your main network and the internet.

3. Restrict internet access: If you’re concerned about specific devices accessing the internet, you can restrict their access using your router’s settings. Most routers allow you to block specific devices from accessing the internet.

Restricting internet access to smart devices

If setting up a private network is not feasible, you can restrict internet access to specific devices. Here’s how:

Access your router’s settings: Log in to your router’s settings using a web browser.

Find the device list: Look for a list of connected devices. This list may be labelled as “Attached Devices” or “Connected Devices”.

Block internet access: Find the device you want to restrict and look for an option to block internet access. This option may be labelled as “Block Internet Access” or “Restrict Internet Access”.

Buying devices that operate on standards

When purchasing smart devices, look for products that operate on standards such as Matter or Thread. These standards ensure that devices from different manufacturers can communicate with each other securely. Devices that operate on these standards are also less likely to have backdoors or other security vulnerabilities.

Not all smart devices need to be connected to the internet. By creating a private network or restricting internet access, you can protect yourself from potential security risks. When purchasing smart devices, look for products that operate on standards such as Matter or Thread. Remember, it’s always better to err on the side of caution when it comes to your personal security and data.

The risks of smart devices: What you need to know
