Class AWTPermission

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.

The following table lists all the possible AWTPermission target names, and for each provides a description of what the permission allows and a discussion of the risks of granting code the permission.

Permission Target Name	What the Permission Allows	Risks of Allowing this Permission
accessClipboard	Posting and retrieval of information to and from the AWT clipboard	This would allow malfeasant code to share potentially sensitive or confidential information.
accessEventQueue	Access to the AWT event queue	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.
accessSystemTray	Access to the AWT SystemTray instance	This would allow malicious code to add tray icons to the system tray. First, such an icon may look like the icon of some known application (such as a firewall or anti-virus) and order a user to do something unsafe (with help of balloon messages). Second, the system tray may be glutted with tray icons so that no one could add a tray icon anymore.
createRobot	Create java.awt.Robot objects	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.
fullScreenExclusive	Enter full-screen exclusive mode	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. Depending on the implementation, the security warning may not be shown for the windows used to enter the full-screen exclusive mode (assuming that the fullScreenExclusive permission has been granted to this application). Note that this behavior does not mean that the showWindowWithoutWarningBanner permission will be automatically granted to the application which has the fullScreenExclusive permission: non-full-screen windows will continue to be shown with the security warning.
listenToAllAWTEvents	Listen to all AWT events, system-wide	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.
readDisplayPixels	Readback of pixels from the display screen	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.
replaceKeyboardFocusManager	Sets the KeyboardFocusManager for a particular thread.	When SecurityManager is installed, the invoking thread must be granted this permission in order to replace the current KeyboardFocusManager. If permission is not granted, a SecurityException will be thrown.
setAppletStub	Setting the stub which implements Applet container services	Malicious code could set an applet's stub and result in unexpected behavior or denial of service to an applet.
setWindowAlwaysOnTop	Setting always-on-top property of the window: Window.setAlwaysOnTop(boolean)	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
showWindowWithoutWarningBanner	Display of a window without also displaying a banner warning that the window was created by an applet	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.
toolkitModality	Creating TOOLKIT_MODAL dialogs and setting the TOOLKIT_EXCLUDE window property.	When a toolkit-modal dialog is shown from an applet, it blocks all other applets in the browser. When launching applications from Java Web Start, its windows (such as the security dialog) may also be blocked by toolkit-modal dialogs, shown from these applications.
watchMousePointer	Getting the information about the mouse pointer position at any time	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.
