Class java.awt.AWTPermission


public final class AWTPermission
extends BasicPermission
This class is for AWT permissions. An AWTPermission contains a target name but no actions list; you either have the named permission or you don't.

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 the system, as well as post bogus events which may purposefully cause the application or applet to misbehave in an insecure manner.
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.
