Protect your data when using public WiFi networks

A good way to keep your information safe when using a public WiFi network is with VPN (Virtual Private Network) software.

Difficulty: Moderately Easy

Instructions

Step 1

VPNs integrate standards-based authentication and encryption technologies to secure data transmissions to and from devices and to protect networks from unauthorized users. A VPN is a private network that uses a public network to connect. A VPN uses "virtual" connections.
Step 2

When connecting to public WiFi, don't automatically accept the first available hotspot. Look for one that comes from a legitimate source.
Step 3

Make sure you've set up the wireless device on your computer with all the security features properly enabled.
Step 4

Run firewall software when using a public network. You have a built-in firewall with the newer Macs. Windows users can get a good firewall from Zone Alarm.

Step 1

Links to all the software mentioned will be found in the Resources section at the end of the article.

A popular free choice is Hamachi. Hamachi claims to work with zero configuration. This means it is easy to setup, and easy to pay for, since there is a free version. It runs on Windows, Mac, and Linux.
Step 2

VPN Labs has lots of links to free or trials versions of VPN software for all operating systems.
