Instructions

Things You'll Need

• A wireless-capable computer

General Overview

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.

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

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

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.
