Tips for Mobile Security -- SmartPhone PDA

How can you be sure your smartphone or PDA is secure?

Wireless carriers offer fairly good encryption and authentication, but it's important for you to understand where the service provider stores your data, such as e-mails, contacts, and photos. With enterprise Blackberry systems, your corporate e-mail server stores the data, making it as safe as your IT department is capable. (continued...)

With personal service plans, however, your e-mail and contacts are probably on a central server within the service provider's facility. You can't depend on the service provider to protect your server-based data. In this case, you can take advantage of your account's auto-aging setting, which deletes your e-mail messages after a specific amount of time.

Change passwords periodically, and make them different than other accounts. I know that this is tough, but a smart hacker might observe you entering a username and password for a non-sensitive account, such as a club bulletin board, and then try that username and password on your bank account.
