a firewall protects you and your computer from threats coming AT you.
a firewall does nothing to ensure your financial transaction is secure.
in order to connect to the internet via wifi, someone has to make a wireless access point available to you. some of those are unsecured/open hotspots, and some of them are secured and provided by the campground you may be visiting.
in either case, you are not directly connecting to your financial institution and its quite possible that the "man in the middle" who provides the hotspot is maliciously capturing your information.
what can you do to ensure you are safe? first of all, always make sure you are using an http
s:// connection to whatever site you are giving up financial information (or any kind of info you want to secure. even addresses and such)
an http
s:// connection, instead of plain old http:// means that at least your communication to/from the website is 'encrypted'... however...
"Encrypted" does NOT automatically mean "safe"!
Anyone can operate a site with SSL that provides an http
s connection to encrypt traffic to and from their server.
But the players that are operating that SSL server
may NOT be who you think it is .
Here's an excerpt from
an article worth reading :
what’s the difference between “encrypted” and “safe”? It turns out that it’s not actually that hard to set up a site that will get your browser to display a padlock. In fact, it’s easy enough that essentially anyone can do it, including bad guys who are just out to steal your credit card info, identity, and whatever else they can get. So the padlock means “encrypted” but doesn’t say anything about the validity of the domain, nor about the identity of the people at the other end of the encrypted connection.
Every bank in the world had better be able to validate themselves to the maximum level of scrutiny. when i want to connect to my bank of america account or my paypal account, i absolutely look for the "green" in my firefox browser to ensure i am connected to who i want to be.
FYI, 3Gstore is one of very few vendors who have gone through the extended validation process to achieve the highest level of security, similar to that of Paypal. In fact, to our knowledge, no other site that sells the products we do, has ever demonstrated the same level of security that 3Gstore maintains.
