Public Wi-Fi networks are ubiquitous — at cafes, airports, hotels, libraries, restaurants, and shopping malls. They offer handy ways to get online while you’re out and about, but they can also present serious dangers to your online safety. Good internet security habits are crucial when using public Wi-Fi to shield your personal information from hackers and cybercriminals. Here’s helpful advice on the dos and don’ts of staying safe on public Wi-Fi.
Staying Safe on Public Wi-Fi: Do’s
A Virtual Private Network (VPN) helps protect your online activity from prying eyes by keeping you anonymous on the web.
A VPN secures your internet connection, making it significantly more difficult for cybercriminals to siphon your data. If you’re trying to keep the internet safe while connected on a public Wi-Fi network, or a Japanese one, there aren’t many better ways out there than a VPN. You connect to VPN, which establishes a secure tunnel between your device and the VPN server, and your browsing and other activities are kept hidden.
Connect Only to Trusted Networks
Check whether the network is legitimate before you connect. Ask staff members for the official Wi-Fi name to prevent accidentally connecting to a dummy hotspot the hackers might have set up. Designed to siphon your data the instant you log in, these rogue networks are.
Enable Two-Factor Authentication (2FA)
Two-factor authentication gives your accounts an extra wall of protection by asking for an extra form of verification (like a text message code or authentication app). If a hacker steals your password on a public network, 2FA can stop them from accessing your accounts.
Keep Your Software Updated
Keep your operating system, browsers, and security software updated. And updates typically include patches for vulnerabilities that hackers could use, particularly when you’re connected to public networks, even for a short time.
Turn Off Sharing Settings
Keep file sharing, printer sharing, and network discovery turned off when on public Wi-Fi. This keeps your files or device away from everyone on the network.
Use Secure Websites
Always ensure that the websites you are visiting have HTTPS, not HTTP, in the addresses. The “S” here means the site encrypts your data. This is especially crucial when inputting login details or payment data.
No-Nos for Staying Safe on Public Wi-Fi
Don’t Log In To Sensitive Sites or Make Financial Transactions
Don’t log into banking websites, payment apps, or other accounts in which you have sensitive payment information when you are using public Wi-Fi. If you do, be sure to use a VPN and be on a site that is secure using HTTPS.
Turn Off Auto Sign-In If You Connect to Public Wi-Fi connections to public Wi-Fi.
Disable your device’s automatic Wi-Fi connection capabilities. Connecting automatically to open networks exposes you to the potential for connecting to fake hotspots without you realizing it.
Don’t Ignore Security Warnings
If your browser or antivirus software flags a website as suspicious or a connection as insecure, don’t proceed. Those alerts are there to protect your internet safety, and you would be wise to take them seriously.
Don’t Disable Your Firewall
It’s also a firewall for your device, keeping out any harmful traffic. Do not under any circumstances turn it off, not even when you are connected to public Wi-Fi: this feature prevents people from gaining unauthorized access to your devices.
Don’t Forget to Log Out
After you are done using a website or service on public Wi-Fi, remember to log out completely. Turning off the browser may leave your session open and permit the hijacking of your account.
Final Thoughts
Public Wi-Fi may be convenient, but it poses extreme risks that can threaten your personal information and online privacy. Good internet safety practices, such as the following do’s and don’ts, can effectively minimize your risk of cyberattack while using public Wi-Fi. Keep vigilant, use reliable means like VPN, and be aware of what the best security practices out there are.
