- /**
- * This class is for AWT permissions.
- * An <code>AWTPermission</code> contains a target name but
- * no actions list; you either have the named permission
- * or you don't.
- *
- * <P>
- * The target name is the name of the AWT permission (see below). The naming
- * convention follows the hierarchical property naming convention.
- * Also, an asterisk could be used to represent all AWT permissions.
- *
- * <P>
- * The following table lists all the possible <code>AWTPermission</code>
- * target names, and for each provides a description of what the
- * permission allows and a discussion of the risks of granting code
- * the permission.
- * <P>
- *
- * <table border=1 cellpadding=5 summary="AWTPermission target names, descriptions, and associated risks.">
- * <tr>
- * <th>Permission Target Name</th>
- * <th>What the Permission Allows</th>
- * <th>Risks of Allowing this Permission</th>
- * </tr>
- *
- * <tr>
- * <td>accessClipboard</td>
- * <td>Posting and retrieval of information to and from the AWT clipboard</td>
- * <td>This would allow malfeasant code to share
- * potentially sensitive or confidential information.</td>
- * </tr>
- *
- * <tr>
- * <td>accessEventQueue</td>
- * <td>Access to the AWT event queue</td>
- * <td>After retrieving the AWT event queue,
- * malicious code may peek at and even remove existing events
- * from its event queue, as well as post bogus events which may purposefully
- * cause the application or applet to misbehave in an insecure manner.</td>
- * </tr>
- *
- * <tr>
- * <td>createRobot</td>
- * <td>Create java.awt.Robot objects</td>
- * <td>The java.awt.Robot object allows code to generate native-level
- * mouse and keyboard events as well as read the screen. It could allow
- * malicious code to control the system, run other programs, read the
- * display, and deny mouse and keyboard access to the user.</td>
- * </tr>
- *
- * <tr>
- * <td>fullScreenExclusive</td>
- * <td>Enter full-screen exclusive mode</td>
- * <td>Entering full-screen exclusive mode allows direct access to
- * low-level graphics card memory. This could be used to spoof the
- * system, since the program is in direct control of rendering.</td>
- * </tr>
- *
- * <tr>
- * <td>listenToAllAWTEvents</td>
- * <td>Listen to all AWT events, system-wide</td>
- * <td>After adding an AWT event listener,
- * malicious code may scan all AWT events dispatched in the system,
- * allowing it to read all user input (such as passwords). Each
- * AWT event listener is called from within the context of that
- * event queue's EventDispatchThread, so if the accessEventQueue
- * permission is also enabled, malicious code could modify the
- * contents of AWT event queues system-wide, causing the application
- * or applet to misbehave in an insecure manner.</td>
- * </tr>
- *
- * <tr>
- * <td>readDisplayPixels</td>
- * <td>Readback of pixels from the display screen</td>
- * <td>Interfaces such as the java.awt.Composite interface or the
- * java.awt.Robot class allow arbitrary code to examine pixels on the
- * display enable malicious code to snoop on the activities of the user.</td>
- * </tr>
- *
- * <tr>
- * <td>replaceKeyboardFocusManager</td>
- * <td>Sets the <code>KeyboardFocusManager</code> for
- * a particular thread.
- * <td>When <code>SecurityManager</code> is installed, the invoking
- * thread must be granted this permission in order to replace
- * the current <code>KeyboardFocusManager</code>. If permission
- * is not granted, a <code>SecurityException</code> will be thrown.
- * </tr>
- *
- * <tr>
- * <td>showWindowWithoutWarningBanner</td>
- * <td>Display of a window without also displaying a banner warning
- * that the window was created by an applet</td>
- * <td>Without this warning,
- * an applet may pop up windows without the user knowing that they
- * belong to an applet. Since users may make security-sensitive
- * decisions based on whether or not the window belongs to an applet
- * (entering a username and password into a dialog box, for example),
- * disabling this warning banner may allow applets to trick the user
- * into entering such information.</td>
- * </tr>
- *
- * <tr>
- * <td>watchMousePointer</td>
- * <td>Getting the information about the mouse pointer position at any
- * time</td>
- * <td>Constantly watching the mouse pointer,
- * an applet can make guesses about what the user is doing, i.e. moving
- * the mouse to the lower left corner of the screen most likely means that
- * the user is about to launch an application. If a virtual keypad is used
- * so that keyboard is emulated using the mouse, an applet may guess what
- * is being typed.</td>
- * </tr>
- *
- * <tr>
- * <td>setWindowAlwaysOnTop</td>
- * <td>Setting always-on-top property of the window: {@link Window#setAlwaysOnTop}</td>
- * <td>The malicious window might make itself look and behave like a real full desktop, so that
- * information entered by the unsuspecting user is captured and subsequently misused </td>
- * </tr>
- *
- * <tr>
- * <td>setAppletStub</td>
- * <td>Setting the stub which implements Applet container services</td>
- * <td>Malicious code could set an applet's stub and result in unexpected
- * behavior or denial of service to an applet.</td>
- * </tr>
