4 Tips to Use Public
Computers Safely
Hey Everyone!
We've all run into a situation when we have to use a public
computer at an internet café, library, or school to check out Facebook,
check banking information or to send an email. User beware! First, you
have no guarantee that the computer is protected; it might be riddled
with viruses, and, second, unless you're careful the next user might
learn a lot more than you'd like about your online session. Here are
some steps I recommend taking before you use that public computer.
1. Don't let the web browser store all of your secrets. Every
web browser on a computer keeps a history of sites you've visited and
downloads the files and information from that web site for faster
loading of sites you visited before. That's fine at home, but when
you're using a public computer, you don't want the browser storing your
history. Fortunately, modern browsers can protect your privacy.
You can right-click on the Firefox icon and choose "Enter private
browsing." For Firefox, pressing Ctrl+Shift+P during a normal browsing
session switches to private browsing. In Chrome, the private browsing
mode is called "Incognito mode." Be sure to shut down the browser when
you're done. Private browsing doesn't disable the Back button so you
don't want the next user backing into your Facebook session or email
account.
2. Don't forget to use private browsing. There's
always the possibility that you forgot to go private and you've already
checked your email or bank account. Erasing your activity is simple. In
Chrome or Firefox, you simply press Ctrl+Shift+Del to call up the
dialog for deleting your history. The details vary, but you'll want to
make sure you've selected all of the options for deletion. Chrome and
Firefox lets you specify how far back to delete, so just clear out all the history just to be on the safe side.
3. Only Visit Financial Sites On Your Own Computer. It's
possible that the computer you're using might be seriously compromised
security-wise. For example, a stealth keylogger application could
capture all passwords typed on the system. A hardware keylogger could do
the same, with no possibility of detection by security software.
Your
best bet is to simply refrain from sensitive transactions on a public
computer. If you absolutely must log in to an important secure site on a
suspect computer, here's one way to make password theft difficult:
bring up a page with lots of text in the browser and copy/paste
characters from that page into the password dialog. This "ransom note"
style is decidedly tedious, but even a spy program that captures
periodic screenshots can't snap all parts of your password.
4. Keep Your Web Site Visits to a Minimum. As
you can see, there's a whole range of precautions you can take to keep
any public computer session from turning into an identity theft
nightmare. If you're forced to use public computers for sensitive
communication, consider using ransom-note passwords and possibly a VPN.
Don't engage in any sensitive communication that you could just as well
do from your home or office. But even if you're doing nothing more than
checking Facebook and e-mailing your dear auntie, do take the minimal
precautions. Invoke the browser's privacy mode, or clear browsing data
if you forgot. Doing so just takes a second and can save hours of
aggravation.
