Free public Wi-Fi could be extremely useful when you go to public places. But most of us may not be aware of the fact that connecting your device to these free unsecured Wi-Fi hotspots could be risky as your data could be intercepted. You are not the only one connected to the network, as it is a public network many people use it. It is easy for someone to intercept your data while using public Wi-Fi. Even if the public Wi-Fi is a secured hotspot then the attacker can intercept your data once they are connected to the hotspot.
Many of the networks give open access to Wi-Fi settings to anyone connected to the network. This can lead to “man-in-the-middle” attacks as anyone can get admin access in these types of networks. Pulling off the incoming and outgoing data in a public network is very easy, so anyone in the network can gain access to the information you send. This information may include your credit card details, passwords, bank details, etc.
How can you stay safe on Public Wi-Fi?
- If you are going to use a network of a public library or restaurant, confirm the network name from the staff before connecting your device.
- Use a virtual private network (VPN). VPN makes it difficult for intruders to steal your data.
- Check whether the website is HTTPS or not (In simple words check for the lock sign).
- Do not forget to click ‘Forget the Network’ after finishing using a public network.
- Do not use services that require sensitive information such as email/password, bank details etc. while using a public network.
- Switch off the sharing services in your device and use a firewall.
