Prevent user hacking while on your laptop

A Good Wednesday Morning all you fellow bloggers!!
I just caught a bit of Canada AM, as they were talking abut protecting  your information while your out there in the airports, train stations, bus stations, subway stations or just sitting at your local coffee shop.
They mentioned that it's important while accessing 'sensitive' information that you look for the secure  https at the beginning of the URL.
I wouldn't want anyone to get their sensitive information stolen by a hacker who happened to be near them. Anyway for what it's worth, here is the web site to today's show. The topic is near the top of the subject lists, in case you're interested.
Hope this information is helpful.
