Safe Surfing Tips While On FREE Wi-Fi


Every place you go, every shop and gathering place you will probably see the “Free Wi-Fi,” sign but is it safe to check your email at the airport, library or Starbucks? There are risks to accessing private data while connected to an unsecured, community network. Here’s how to surf safely when you’re on public Wi-Fi.

When you access the Internet on a public network, your computer or Smartphone is at risk of being accessed by other users on the same network.  It’s surprisingly easy for the person sipping the Macchiato next to you to run simple programs to collect passwords and information entered by fellow patrons.  Most Wi-Fi “hotspots” are unencrypted since it’s a hassle to make every customer find out the day’s Wi-Fi password, meaning even if you’re alone in the store someone sitting in the parking lot could be connected to the network.

It may seem unlikely that your data will be hacked, and that’s probably true.  But just like you might be able to leave your car unlocked and never suffer a break-in, is it worth the risk?  Anyone who’s had their Facebook account hacked or banking password compromised can attest that it can take months or more to put your online identity back in order.

Luckily there are some easy steps you can take to protect yourself on public Wi-Fi.  Since logging on to a network gives other users on that network access to your shared folders, the first thing to do when you’re on a public network is to turn off sharing.  Windows users should navigate to the Control Panel, then Network and Internet.  Select the option to “Choose homegroup and sharing options” and then select “Change advanced sharing settings…” Turn off file and printer sharing and public folder sharing.  If you’re using a Mac, go to System Preferences and then Sharing.  Make sure all boxes are unchecked.

Consider also disabling network discovery as it prevents others from seeing your machine on the network.  You can re-enable it when you’re no longer logged on to a public network.

Next, enable your system’s internal firewall.  Windows users should go to Control Panel and then System and Security.  Select Windows Firewall and choose “Turn Windows Firewall on or off” from the list of options on the left.  Mac users can turn on their firewall via System Preferences.  Choose Security and then Firewall to activate.  This won’t keep out a skilled hacker, but it can deter a casual snooper.

Make sure that websites that contain private data (like your email or bank) have https:// preceding the web address.  This denotes a secure (i.e. encrypted) connection which makes it more difficult for someone who gets a hold of the data sent or received by your computer to decode it into usable material.  If you’re just catching up on your celebrity gossip, surfing http sites isn’t a big deal; just make sure to look for the https before entering any passwords.  If the web address changes from https to http while you’re navigating between pages, log out immediately and wait to check your bank balance when you’re on a secure network.

Instruct Gmail to automatically connect over https by logging into your email account and selecting the icon on the upper right that looks like a cog.  Choose settings, then General and under “Browser connection:” choose “Always use https.”

HTTPS Everywhere is a browser extension for Firefox or Chrome that encrypts your communication with sites like Google Search, Facebook, Twitter and more.  It can even redirect you to the secure version of a page you access via another person’s or site’s link.

Lastly, the best secure option is to get a VPN service: for a few dollars per month, you will ensure your data remains private and your computer and mobile devices secure. Through its technology, a VPN allows you to establish an encrypted VPN tunnel to a host (or server) on the Internet. After activating a VPN, your IP address is automatically replaced by an anonymous IP address in the country where your server is based. You can surf anonymously and without restriction: it is impossible for others to intercept your traffic because all the data you are sending is encrypted. This makes your Internet activity impossible to be monitored.
