Question

【题目】Thanks to expensive data fees, you might be tempted to log onto that free public Wi-Fi service while you’re out and about. 【1】

“Think about the cost of being connected all the time. Nothing is free,” David Lee, a product manager for Norton, told CNBC. “【2】” The Harvard Business Review agrees: “You’re taking a risk every time you log on to a free network in a coffee shop, hotel lobby, or airport lounge.”

【3】 According to a survey by the company Symantic, 87 percent of U.S. consumers have used a public internet connection. And it was found that over 70 percent of them checked their personal email through public Wi-Fi, while 11 percent logged onto their online banking account.

No matter how safe the Wi-Fi connection seems to be, using it leaves your computer or smart phone easy to be attacked by hackers and data thieves. You don’t really know who owns and monitors that router, nor who has access to the data that posses through it. Not to mention, hackers have dozens of ways to compromise public Wi-Fi accounts, from creating a network that appears legal to creating pop-ups that trick the user into downloading malware (恶意软件) onto their computers.【4】

To protect yourself against hackers, experts say your best defense is a virtual private network (VPN), which encrypts (加密) your online activity. You can download your very own VPN through an app for Apple or Android devices, or by using the free encryption service CyberGhost.【5】 But before you even start browsing, use this website to make a password that keeps you safe from hackers.
