Connected devices – smart TVs, voice assistants, watches, cameras, fridges, vacuum cleaners, etc. – are now part of our everyday lives. They simplify our lives, keep us informed and entertained... but they can also pose a risk if they are not properly protected.
A connected device is a potential gateway to your private life. By following a few simple steps, you can reduce the risk of hacking without needing to be an expert.
What are the risks?
A poorly secured connected device can allow a hacker to:
- listen to or film you without your knowledge via a remotely activated camera or microphone,
- monitor your habits (e.g. when you are away, when you are asleep),
- control certain devices remotely (open a door, turn off the heating, etc.).
Six habits to secure your connected devices
1. Do your research before buying
Before splashing out on a new connected device, take the time to check:
- online reviews (stick to reliable websites or specialist comparison sites),
- whether the manufacturer regularly updates its products,
- whether support is available in case of problems.
Avoid very cheap products or those without a recognised brand name: they are often less secure.
2. Change the default passwords
Many devices come with a factory-set password that is known to everyone. Change it as soon as you install the device.
- Use a unique password that is difficult to guess (at least 14 characters, including numbers and symbols).
- Do not use the same password for multiple devices.
3. Install updates
Install updates as soon as they become available. These updates often fix security vulnerabilities.
- Enable the automatic update option if available.
- If this is not possible, set a monthly reminder to check.
4. Secure your Wi-Fi
Your internet connection is the link between your devices and the outside world. It must be well protected.
- Change the network name (SSID) and avoid including your name or address.
- Choose a strong Wi-Fi password.
- Limit the number of devices allowed to connect.
- Create a guest network for your visitors. This provides separate, isolated access.
- Restart your modem from time to time and remember to update it.
5. Disable unnecessary features
Some connected devices activate features you don't need by default (e.g. microphone, Bluetooth, geolocation).
- Review the settings on each device.
- Disable anything you don't use.
6. Monitor what is connected
Get into the habit of checking the devices connected to your network:
- Via your modem/router app or its web interface.
- Delete any unknown or unused devices.
What if you're unsure or think you've been hacked?
Think one of your devices has been hacked? Here's what to do:
- Immediately disconnect the device from the internet (unplug it or turn off Wi-Fi).
- Restore the factory settings if you can't secure it.
- Change all passwords linked to the device.
- Contact the manufacturer or an authorised technician for help.
- Report the incident to the police if you think there has been data theft or an attempt at fraud.
