Financial Friday: Wi-Fi Watchers
Not to sound paranoid, but strangers are watching you and, especially, what you’re doing online. Thieves know where the public Wi-Fi spots are and can use a sniffing device to see what’s happening on your network. You wouldn’t let them watch through your bedroom windows; stop them from looking at your personal online interactions with the tips below:
- Watch for nosy onlookers. They may be trying to steal information from your smartphone, tablet or laptop.
- Password protect your devices and sensitive apps.
- Body block or otherwise cover the keyboard when entering passwords.
- Use only trusted Wi-Fi networks (not public ones) to
- Access your financial information.
- Make purchases.
- Send sensitive emails.
- When using a website, check the address. A secure webpage will begin with “https:” not just “http:” Think of the extra “s” as meaning “secure.”
- Logout after each use.
It’s safer to turn off public Wi-Fi and enable your mobile carrier’s network or a personal Wi-Fi hotspot. You can get a personal Wi-Fi hotspot from your wireless provider, but it may cost extra.
- If you’re uncertain but you want to access a website anyway, use an alternative browser. Switch from Firefox to Chrome, for example, when using a site you’re not sure about. This tactic protects your browsing history and passwords.
- Create a portable router with a local SIM data card, which you can get at electronic stores and most airports.
To summarize, only use shared PCs and public Wi-Fi for low-risk activities that don’t require a login and password, like checking the news, weather or directions to your destination. Basically, only use free Wi-Fi if you don’t mind strangers watching what you are doing.
