Avoid checking your email when you’re on public Internet. Yes, I know that when you’re waiting for an airplane to reach your gate, it can be tempting to whip out your smartphone or laptop and check for new messages. Unfortunately, public Wi-Fi can be extremely insecure.

There are programs out there called “network sniffers” that run passively in the background of some hacker’s device. The sniffer monitors all of the wireless data flowing through a particular network – and that data can be analyzed for important information. Like your username and password.

It’s strange that as the years go by, security grows tighter in some ways and we remain just as vulnerable as we’ve always been in other ways. Email security comes down to common sense and careful decisions. Don’t let laziness and convenience overshadow your desire for protection and peace.
