    14 <p>The superior mobility and connectivity of mobile devices constitutes
       
    15 their greatest threat, and allows intruders to try different attack methods
       
    16 against the device. The figure below illustrates the most common methods of
       
    17 attack against mobile devices.</p>

    19 <p>Due to the nature of mobile devices, including the potential vulnerabilities
       
    20 mentioned above, you should consider the following points when designing your
       
    21 application:</p>
       
    22 <ul>
       
    23 <li><p>If a mobile device is lost or stolen, confidential information
       
    24 (for example, calendar and contacts) can be read even by those with little
       
    25 expertise.</p></li>
       
    26 <li><p>Users can access confidential information and files at any
       
    27 time, including reverse engineering of software and algorithms.</p></li>
       
    28 <li><p>Data can be transferred from and to the mobile device through
       
    29 different methods, even accidentally. </p></li>
       
    30 <li><p>Users may detach removable media or the battery at any time,
       
    31 which can cause data loss or corruption.</p></li>
       
    32 </ul>
       
    33 <p>When you handle confidential information in your application, remember
       
    34 that with sufficient motivation and resources there are always ways to extract
       
    35 information from a mobile device. As the level of software security improves
       
    36 and attacks become less practical, interest in hardware attacks may in turn
       
    37 increase.</p>
       
    38 <p>In the continuously evolving digital world, every application should
       
    39 have a certain level of robustness against a changing and hostile environment.
       
    40 Applications should be prepared for data corruption and alteration, network
       
    41 and storage blackouts, plug-ins and components that misbehave, malicious attackers,
       
    42 and, perhaps most importantly, user errors.</p>
