How to Protect Bluetooth intrusions

Peer to peer (P2P) file sharing has become popular but not without a heightened amount of threats. Users often receive files from unknown senders which can lead to security problems, especially with music and media sharing. Like any personal computer, these files can be malware that infiltrate and cause havoc within your laptop. The entry points for intruders are the very same open ports that allow you to transfer files.

Make sure to only perform file transfers from trusted sources. Besides reducing the risk of downloaded files having malware, there’s an element of accountability. Hence you get a better response if there is a problem. Keep an anti-virus scanner handy when transferring files over Bluetooth or P2P. While it may slow down the transfers, it’s definitely much safer. Sometimes, after you discover an intrusion, you are left with no option but to format your hard drive and reinstall your operating system. Keep backups of important data so you can restore your important files quickly. Typical backup methods apply here, and just like before, keep your info in a secure location separate from your laptop to ensure it remains unaffected. Remember to turn off Bluetooth when you’re not using it.

To turn off Bluetooth on a Windows Pocket PC enabled device:
1. Click on the Windows icon in the top left corner of the screen and choose Settings.
2. In Settings, choose Connections and then Bluetooth.
3. If you see that Bluetooth is turned on, click on the Turn Off button.

You can also use the passkey option to eliminate unwanted connections. Only people who have a personal password can connect to your device. This way, you are notified if anybody tries to establish a connection with you.

To use passkey, click on the Bluetooth Manager and select Passkey. You can protect your mobile device by preventing other devices from finding you and connecting to you. This way, you can still connect to other devices, but they cannot connect to you first. This protects you from sneak attacks.

To disable discovery on a Windows Pocket PC-enabled device:
1. Click on the Windows icon in the top left corner of the screen and choose Settings.
2. In Settings, choose Connections and then Bluetooth.
3. Click on Accessibility to get to the screen shown in the figure below.
4. Uncheck the “Allow other devices to connect” and “Other devices can discover me” boxes.

Finally, make sure the public network you are accessing is secure. If a network does not ask you to identify yourself with a password, then beware. Just about anyone can log onto the same network as anonymously. It’s better to avoid unfamiliar networks than to risk any attacks.
