The best way to ensure your PlayBook is secure while browsing on a Wi-Fi network is to only employ networks secured with the latest Wi-Fi security standards, and by only surfing on networks you know and trust. Sometimes that means avoiding free, open networks in coffee shops, airports and hotels.

You're always better off using your own, secure Wi-Fi hotspot or home network where available, or at least paying for secure access to a locked network, but sometimes you don't have access to these wireless networks. If you do decide to employ an open or public network, beware that someone else could possibly access information stored on your tablet, and try to reduce the transfer of sensitive information, like passwords or financial details such as credit card numbers.

The BlackBerry PlayBook lets you employ Wi-Fi Protected Setup (WPS) so you can connect to compatible Wi-Fi networks via buttons or PIN numbers on a wireless router, therefore never having to send passwords or other potentially sensitive login information over the network. To employ the PlayBook's WPS options, click the PlayBook Settings icon in the top right corner of your tablet's home screen, but this time pick Wi-Fi from the list of options. Then tap the Use WPS option and follow the on-screen instructions.

Finally, you can reduce the risk of unauthorized access to your PlayBook via Bluetooth by ensuring that your tablet is not "discoverable" at all times. To modify your PlayBook Bluetooth settings, open the PlayBook Settings and pick Bluetooth. Next, make sure that the Discoverable option is set to either No or 2 Minutes.

You'll need to go into your PlayBook's Bluetooth settings and pick 2 Minutes every time you want to pair with another Bluetooth-enabled device, since this option will make your tablet detectable for only two minutes before making is "disappear." But unknown Bluetooth devices won't even be able to detect your tablet when it's not discoverable, let alone connect without your knowledge.
