IoT and Connected Objects: Unlock the Power of a Secure Wi-Fi Network

In a world increasingly focused on connectivity, IoT and connected objects have become indispensable: smart thermostats, voice assistants, surveillance cameras. Practical and intuitive, they make life easier. But since these devices are connected to your Wi-Fi network, they can also represent a gateway for cybercriminals? That’s why computer security has never been so crucial to protecting your personal data and that of your loved ones.

Secure your home wifi network with a segment dedicated to IoT and connected objects

Think of your home Wi-Fi network as a small business: every connected device is an employee. To ensure the security and efficiency of your business, you wouldn’t let every employee have access to all your confidential information. Similarly, by creating a dedicated segment for connected objects, you isolate these devices from the rest of your wifi network.

Why isolate your connected objects from the rest of your home network?

• Damage limitation in the event of intrusion: if a connected object is compromised, damage will be limited to the dedicated segment. Devices in other segments remain safe.
• More efficient management: you can apply specific security rules for each segment, for example, blocking Internet access for certain connected objects.
• Optimized performance: by isolating connected objects, you reduce traffic on your Wi-Fi network, improving its overall performance.

Disable WPS and SSID visibility: Extra protection

Although WPS makes it easy to connect a device quickly, it is also a security vulnerability. Similarly, masking the SSID (Wi-Fi network name) prevents unauthorized persons from easily detecting your network.

What to do?

• Disable SSID broadcast: in your router settings, you can disable SSID broadcast. This means your network will no longer be visible to nearby devices.
• Use a strong password: even if your SSID is not visible, it’s essential to use a complex password to protect your network.

Other tips for securing your network and connected objects

• Use strong, unique passwords: avoid using the same password for all your devices, and prefer complex passwords combining capital letters, numbers andspecial characters. Tip: change your Wi-Fi network password regularly to maintain a high level of security.
• Activate WPA3, the latest security protocol: if your router allows it, opt for WPA3 instead of WPA2. This standard provides enhanced digital security and protection for your connected objects.
• Create a guest network: if you have visitors, set up a separate guest Wi-Fi network. This will prevent external devices from accessing your sensitive files or connected objects, reducing the risk of intrusion.
• Update the firmware of your router and connected objects: firmware updates correct security flaws and improve the performance of your devices and your wifi network in general. Be sure to check frequently for updates.
• Change default credentials: immediately replace the default passwords on your connected devices, as these can be easily found by hackers.

In the age of Wi-Fi networks and connected objects, digital security is more important than ever. By adopting effective security practices and segmenting your Wi-Fi network, you can significantly reduce the risk of intrusion and protect your privacy. Don’t forget that IT security is an ongoing process: it’s crucial to remain vigilant and regularly update your knowledge of the subject.
