For one, if the iPad employs encryption the same way the iPhone does, sensitive personal data, including phone numbers and e-mail addresses, could be retrieved and viewed, says Daniel Hoffman, chief technology officer at SMobile Systems, which sells mobile security software.
"The problem with the iPhone security encryption is it is fundamentally worthless," he said. "It can be easily bypassed."
Secondly, if iPad users get their apps from the Apps Store, they are at risk of getting the occasional bad apple, Hoffman said, noting that there have been malicious apps found in the store.
In addition, the device is subject to man-in-the-middle attacks like any other device that uses unsecured Wi-Fi networks, he said.
