+<p>If you are developing an application with a user interface, consider
+the following issues:</p>
+<ul>
+<li><p>Other applications may have access to the information that
+the user inputs.</p></li>
+<li><p>A hostile application may lure the user to enter information
+that belongs to another application.</p></li>
+</ul>
+<p>Password dialogs in particular should be designed so that the user easily
+recognizes the currently running application.</p>
+<section id="GUID-836A84FD-44E9-4C3F-AA50-4BC36CBA2916"><title>User input</title>
+<p>It is possible for the user to unintentionally enter incorrect data
+that can interfere with the normal operation of the application. All input
+should be checked and validated before processing. A one-time check may not
+be enough because the content of data can change during processing, so it
+is therefore advisable to quickly check the data every time it is used.</p>
+<p>The following figure shows an example of input processing phases.</p>
