OK, here's what prompted me to raise this question in the first place.
It's a Q&A from the Wall Street Journal Mossburg column of May 3 at this
Here's the exact quote that has me concerned.
"Q I am concerned about security on my laptop when traveling and using
nonsecure Internet connections available at motels. Is there a way to be
secure when accessing my financial Web sites while using a motel's
A. You can install a good firewall, and sweep your laptop with security
software for spyware and other malicious software that might transmit
passwords. And you can make sure you are using antiphishing software.
Better yet, you could use a sort of private Internet tunnel, called a
Virtual Private Network, or a remote control service, like GoToMyPC, so
you are actually using your home PC --- remotely --- to contact the Web
But, the bottom line is that, unless you are on a network that you can
control and secure, such as a home or office network, I wouldn't advise
accessing financial accounts online, or performing financial
transactions. I wouldn't trust sensitive online transactions to any
public Internet connection, such as those at motels. There are too many
people, including other guests, the motel staff, and the people at the
company that provides the motel's Internet service, who could
potentially be watching what you are doing."
Is Mossburg just wrong when he says even https connections aren't safe
on public internets?
