Using free public WiFi at a coffee shop or airport hot spot is great for convenience, but bad for security. Most free access points do not make use of encryption. This is done for convenience and ease of access. If every person had to ask the barista or gate attendant for the WiFi key, it would get unruly, and no actual work would get done.
Keep in mind that you are sharing those wireless airwaves with anyone that is within range of your wireless communications.
There is technology out there that allows you to view the wireless computer communications that are within range of your device. To the bad guys, this technology lets them see what you are doing, the data you are passing to websites, and your usernames and passwords.
Beware Free Wifi. VPN is your friend.
- You are on websites with ‘https’ … the little S is for secure. Its like speaking a language that only two people can understand (your computer, and the website).
- You are using VPN software to encrypt all your wireless communications
