Free Wi-Fi is convenient to use but it’s not without its flaws. Beyond some occasional speed hiccups, the biggest concern is security. It can be a hacker’s playground. So before you jump on the strongest, open signal you see in your vicinity, always ensure that you’ve picked the legitimate network. Here’s what you should do to stay safe on public wi-fi!
3 essential tips to stay safe on public wi-fi when you connect
It’s unlikely that someone will be snooping on the public network you’re connected to directly but it only takes an instance to lead to identity theft, or other events of misfortune. So, you do need to exercise caution in how you use it.
1] Avoid auto-joining any public network
Places like hotels or shopping malls run networks that are often built favoring guest convenience over robust security practices. Cyber-criminals exploit this loophole.
Places like hotels and shopping malls often prioritize guest convenience over strong security measures, making them prime targets for cyber-criminals. They might set up their own malicious network with a similar name to the hotel’s network and with that same SSID through a capability built into Wi-Fi Pineapples, malicious routers designed to intercept traffic.
Guests may unknowingly connect to the rogue network, exposing their devices and potentially compromising their personal or business data. To protect yourself, set your devices to ask for permission before connecting to a network, so you can ensure it’s safe before joining.
As a precautionary measure, you can set most devices to ask for permission to connect to a network, instead of letting them to automatically latch onto the strongest open network signal, or a network you might have joined before. That way you get to decide whether it’s safe to connect or not.

2] Disable File sharing
You’re unknowingly giving other people on the network access to your files when you have the file sharing enabled. This means someone could view or download sensitive information, such as your financial records or personal photos.
Typically, for sharing services like printing or sending files you should be connected to a network. If it’s the ‘Public’ Wi-Fi network you connect through your PC, be it Windows or Mac, leaving the sharing option open at hotspot, you’re giving bad guys easy access. Make sure to turn off file sharing and mark the Wi-Fi connection as a public network.
