Using non-secure Internet Wi-Fi or shared public computers that you can find in public libraries, hotel lobbies, car dealer waiting areas and other public spots sure can be convenient, but using them does come with some risks.
Free wireless Wi-Fi networks are not password protected and are not secure connections. You should be cautious when you are using them.
Since you are sharing these networks with others, it’s possible that someone could be snooping into what you are doing.
You should limit your exposure by keeping your usage to just casual Web browsing and not visiting important sites that require you to log in with a password.
And don’t access financial or serious sites, like your bank account, from one of these hotspots or public computers.
If you are prompted to update software while you’re on one of these public networks, don’t do it. Just wait until you get home to run any updates.
When you travel, it’s not a bad idea to ask the hotel front desk for the name of their Wi-Fi system. ID thieves have been know to put up fake networks while they are staying at a hotel and then try to trick other guests into logging into their network instead of the hotel’s network.
Shared public computers carry the added risk of containing malware or keystroke logging software that bad guys have installed on them.
You can certainly use these PCs for casual browsing, but just don’t log in to any website where you really want to keep your password a secret (just in case).
