The Federal Trade Commission, the nation’s consumer protection agency, today released tips to help people protect their personal information while they use public wireless networks – Wi-Fi hotspots in coffee shops, libraries, airports, hotels, universities, and other public places. While convenient, public Wi-Fi networks often are not secure.
When using wireless networks, it’s best to send only personal information that is encrypted – either by an encrypted website or a secure network. Encryption scrambles information sent over the internet into a code so that it’s not accessed by others. An encrypted website protects only the information sent to and from that site. A secure wireless network encrypts all the information sent over it.
To determine if a website is encrypted, look for https at the beginning of the web address (the “s” is for secure), and a lock icon at the top or bottom of the browser window. Some websites use encryption only on the sign-in page, but if any part of the session isn’t encrypted, the entire account could be vulnerable. Look for https and the lock icon throughout the site, not just at sign in.
Most Wi-Fi hotspots don’t encrypt the information sent over the internet and are not secure. If a person uses an unsecured network to log in to an unencrypted site – or a site that uses encryption only on the sign-in page – other users on the network can see what is sent. New hacking tools – available for free online – make this easy, even for users with limited technical know-how. A Wi-Fi user’s personal information, private documents, contacts, family photos, and even login credentials could be up for grabs.
