How to Protect a Computer When Using Public Wireless Internet

Public wireless Internet spots are definitely convenient because they are everywhere--and because they are available practically anytime. The only problem is that there is no guarantee how secure the network is. Hackers and scammers can connect into unsecured connections and collect your personal information. You have to protect your computer when using public wireless Internet. Follow these steps to help keep your information secure.

Instructions

Difficulty: Easy

1. Use public wireless Internet spots only to surf the Web. Do not conduct your business or work on projects that contain proprietary information.
2. Hold off on doing your online banking or managing credit card accounts until you are able to use a secure connection. You run the risk of your account information being intercepted.
3. Do not do any online shopping or make transactions that require you to give out credit card or bank account information, including car insurance, hotel reservations and airline ticket purchases.
4. Disconnect any file sharing or networked computers when using a wireless Internet hotspot. Hackers could gain information from linked computers.
5. Use a firewall to give you better protection. Windows XP and Vista have service packs with built-in firewalls. If you are not using Windows XP or Vista visit the Microsoft website for information on how to set up a firewall on your computer.
6. Turn off your wireless network when you are in a public area that has a wireless Internet connection and you are not using yours. If your Wi-Fi card is external than you can take it off. If it is internal than right click on your connection and select "Disable."
