I learned a few things about Wi-Fi Security in this explanation by Dave in Computoredge Magazine. It may help you too.
When you are using a Wi-Fi connection, or for that matter, anytime you are communicating over the Internet, the only time your information is secure is when you are using a secure (encrypted) connection. In Web browsing, an encrypted connection is accomplished through TLS (Transport Layer Security), previously SSL (Secure Socket Layer). Rather than using the standard port 80 for Web connections, TSL uses port 443. The browser knows this and looks for a valid Security Certificate from the Web site.
In most Web browsers, you can identify a secure TSL page by the “s” in https:// and the “closed padlock” icon on the end of the address field. See the figure below. Anytime you are sending private information over the Web, make sure that these appear. When you log on to the connection, it should be through a secure page. Also, any online business (purchases, banking, etc.) needs to be done through encrypted (TSL) Web pages. (Not all browser versions will display the “closed padlock” icon.)
Figure 2. See the https on the left and the “closed padlock” on the right for a secure (encrypted) Web site.
These browser indications (https and the icon) are not foolproof. If you want be sure that you are at the right Web site, then examine the Security Certificate. (Click on the “closed padlock” icon and select “View certificates.”) The URL, or address, should match the address line. Browsers will give warnings if a Security Certificate doesn’t look right.
You need to understand that most Internet communications are not encrypted and therefore not secure. E-mail is particularly vulnerable since it is rarely ever encrypted. As it bounces from e-mail server to e-mail server on its way to its destination, it can be intercepted. You should never put confidential information (credit card info, Social Security numbers, etc.) into an e-mail.
If you don’t know that you are using an encrypted connection, then you should always treat the Internet communication as vulnerable to public viewing. Plus, none of this protects you from the person looking over your shoulder at the coffee house.
