IT
seems you can surf the Internet and check your e-mail from virtually
anywhere these days—in coffee shops, hotel lobbies, airport terminals
and airplane cabins.
More
places are making it easier to turn on your laptop or tablet computer
and connect to the Internet through free public Wi-Fi hot spots.
But much like leaving
your diary on a park bench, connecting to the Internet using a public
Wi-Fi allows anyone with the right software to see what you are doing.
Worse,
you risk being hit with malware and other virulent programs that can
turn your computer into botnets controlled by hackers to attack web
sites.
Here are some tips to protect your computer from digital eavesdroppers and malicious hackers:
Before leaving home:
• Enable SSL connections:
One of the most effective ways you can to protect your Web surfing is
to use secure connections. As you probably have noticed whenever you log
into your bank’s web site, your browser displays a lock icon or adjusts
the URL bar. This is your browser indicating that you are visiting the
web site over a Secure Sockets Layer, or SSL, connection. An SSL
connection encrypts the information exchanged between you and your bank,
keeping others out.
SSL
connections are usually enabled for bank web sites and other sites that
hold sensitive information, but they can be costly for large companies,
which is why many don’t have them turned on automatically. But you can
enable an SSL connection easily on many of your most used sites:
• Gmail:
Most people have a Gmail account nowadays for their e-mail, and it’s
always important to make sure your e-mail are safe. To enable an SSL
connection for your Gmail account, click on the gear icon at the top
right of the page, click Mail Settings, select Always Use HTTPS, and
save.
• Twitter: Go to your settings, scroll to the bottom of the Account tab, check the box for Always Use HTTPS and save.
• Facebook:
Some people stay logged on to Facebook throughout the day, so making
sure your connection is secure can go a long way. To switch on the SSL
connection, go to Account Settings and click the Security tab. Once
there, edit Secure Browsing and check the box that offers browsing on a
secure connection. Unfortunately for heavy Facebook app users, you will
have to disable this when you run programs such as “FarmVille.”
• Disable sharing:
People often enable sharing to connect with printers and other devices
wirelessly. As useful as this can be at home, leaving sharing on in
public areas is like leaving your door unlocked in a bad neighborhood.
Here’s how to turn it off:
For
Macs, launch your system preferences and click on the Sharing icon.
Uncheck all of the boxes to disable sharing. To turn them back on,
simply check whatever you’re going to use.
For
PCs, Windows will ask you if you are connecting to a home, work or
public network when you connect to a new Wi-Fi network. If you select
public, Windows will disable sharing for you. If you’d like to do this
yourself on Windows XP and 7, click the Start button and launch the
Control Panel.
Here
is where the method changes depending on your version of Windows. For
Windows XP, click on Network Connections and right-click Local Area
Connection. Click Properties and from there uncheck the box that offers
file and printer sharing and then click OK. Check it to enable file and
printer sharing again. For Windows 7, click Network and Sharing Center,
and select Change Advanced Sharing Settings on the left. Click on the
arrow of the network you’d like to disable sharing on, select Turn Off
File and Printer Sharing, and save.
• Turn off Wi-Fi:
One more precaution you can take is to turn off your Wi-Fi before
heading out to avoid having your computer latch on to an unsafe network
on its own.
For Macs, click the Wi-Fi icon on the top right corner called Airport. Select Turn Airport Off.
For PCs, right-click the wireless icon on the task bar and turn it off.
Once you’re there:
• Turn on Wi-Fi: Follow the same steps to turn your Wi-Fi on when you arrive at your destination and select the desired network.
• Log in using a VPN:
If you can log into a virtual private network, your online experience
will be that much safer. Most companies give employees with network
access at the office a way to log into the company VPN from outside.
Enabling the company VPN will encrypt your browsing and work as a
shield.
If you don’t work for a company or have access to the company VPN, you can buy a VPN account with a third party.
This will give you that same protection and encrypt your activity.
Once you leave:
• Turn off Wi-Fi: Should you go to another public spot, this will prevent the computer from automatically connecting to an unsecured network.
