     21 <a name="secure" id="secure"></a><h2>Is Android secure?</h2>
     22 
     23 <p>The security and privacy of our users' data is of primary importance to the
     24 Android Open Source Project. We are dedicated to building and maintaining one
     25 of the most secure mobile platforms available while still fulfilling our goal
     26 of opening the mobile device space to innovation and competition.</p>
     27 
     28 <p> A comprehensive overview  of the <a
     29 href="http://source.android.com/tech/security/index.html">Android
     30 security model and Android security processes</a> is provided in the Android
     31 Open Source Project Website.</p>
     32 
     33 <p>Application developers play an important part in the security of Android.
     34 The Android Platform provides developers with a rich <a
     35 href="http://code.google.com/android/devel/security.html">security model</a>
     36 that to request the capabilities, or access, needed by their
     37 application and to define new capabilities that other applications can request.
     38 The Android user can choose to grant or deny an application's request for
     39 certain capabilities on the handset.</p>
     40 
     41 <p>We have made great efforts to secure the Android platform, but it is
     42 inevitable that security bugs will be found in any system of this complexity.
     43 Therefore, the Android team works hard to find new bugs internally and responds
     44 quickly and professionally to vulnerability reports from external researchers.

     48 <a name="issue" id="issue"></a><h2>I think I found a security flaw. How do I
     49 report it?</h2>
     50 
     51 <p>You can reach the Android security team at <a
     52 href="mailto:security (a] android.com">security (a] android.com</a>. If you like, you
     53 can protect your message using our <a
     54 href="http://code.google.com/android/security_at_android_dot_com.txt">PGP
     55 key</a>.</p>
     56 
     57 <p>We appreciate researchers practicing responsible disclosure by emailing us
     58 with a detailed summary of the issue and keeping the issue confidential while
     59 users are at risk. In return, we will make sure to keep the researcher informed
     60 of our progress in issuing a fix and will properly credit the reporter(s) when
     61 we provide the patch. We will always move swiftly to mitigate or fix an
     62 externally-reported flaw and provide updates to users. </p>

     65 <a name="informed" id="informed"></a><h2>How can I stay informed about Android security?</h2>
     66 
     67 <p>For general discussion of Android platform security, or how to use
     68 security features in your Android application, please subscribe to <a
     69 href="http://groups.google.com/group/android-security-discuss">android-security-discuss</a>.

     73 <a name="use" id="use"></a><h2>How do I securely use my Android phone?</h2>
     74 
     75 <p>Android was designed so that you can safely use your phone without making
     76 any changes to the device or installing any special software.  Android applications
     77 run in an Application Sandbox that limits access to sensitive information or data
     78 with the users permission.</p>
     79 
     80 <p>To fully benefit from the security protections in Android, it is important that
     81 users only download and install software from known sources.</p>
     82 
     83 <p>As an open platform, Android allows users to visit any website and load
     84 software from any developer onto a device. As with a home PC, the user must be
     85 aware of who is providing the software they are downloading and must decide
     86 whether they want to grant the application the capabilities it requests.
     87 This decision can be informed by the user's judgment of the software
     88 developer's trustworthiness, and where the software came from.</p>
     89

     91 <a name="malware" id="malware"></a><h2>I think I found malicious software being
     92 distributed for Android. How can I help?</h2>
     93 
     94 <p>Like any other platform, it will be possible for unethical developers
     95 to create malicious software, known as <a
     96 href="http://en.wikipedia.org/wiki/Malware">malware</a>, for Android. If you
     97 think somebody is trying to spread malware, please let us know at <a
     98 href="mailto:security (a] android.com">security (a] android.com</a>. Please include as
     99 much detail about the application as possible, with the location it is
    100 being distributed from and why you suspect it of being malicious software.</p>
    101 
    102 <p>The term <i>malicious software</i> is subjective, and we cannot make an
    103 exhaustive definition.  Some examples of what the Android Security Team believes
    104 to be malicious software is any application that:
    105 <ul>
    106     <li>uses a bug or security vulnerability to gain permissions that have not
    107     been granted by the user</li>
    108     <li>shows the user unsolicited messages (especially messages urging the
    109     user to buy something);</li>
    110     <li>resists (or attempts to resist) the user's effort to uninstall it;</li>
    111     <li>attempts to automatically spread itself to other devices;</li>
    112     <li>hides its files and/or processes;</li>
    113     <li>discloses the user's private information to a third party, without the
    114     user's knowledge and consent;</li>
    115     <li>destroys the user's data (or the device itself) without the user's
    116     knowledge and consent;</li>
    117     <li>impersonates the user (such as by sending email or buying things from a
    118     web store) without the user's knowledge and consent; or</li>
    119     <li>otherwise degrades the user's experience with the device.</li>
    120 </ul>
    121 </p>

    123 
    124 <a name="fixes" id="fixes"></a><h2>How do Android-powered devices receive security
    125 fixes?</h2>
    126 
    127 <p>The manufacturer of each device is responsible for distributing software
    128 upgrades for it, including security fixes. Many devices will update themselves
    129 automatically with software downloaded "over the air", while some devices
    130 require the user to upgrade them manually.</p>
    131 
    132 <p>Google provides software updates for a number of Android devices, including
    133 the <a href="http://www.google.com/nexus">Nexus</a>
    134 series of devices, using an "over the air" (OTA) update. These updates may include
    135 security fixes as well as new features.</p>
    136 
    137 <a name="directfix" id="directfix"></a><h2>Can I get a fix directly from the
    138 Android Platform Project?</h2>
    139 
    140 <p>Android is a mobile platform that is released as open source and
    141 available for free use by anybody. This means that there are many
    142 Android-based products available to consumers, and most of them are created
    143 without the knowledge or participation of the Android Open Source Project. Like
    144 the maintainers of other open source projects, we cannot build and release
    145 patches for the entire ecosystem of products using Android. Instead, we will
    146 work diligently to find and fix flaws as quickly as possible and to distribute
    147 those fixes to the manufacturers of the products through the open source project.</p>
