Description
Internet Explorer allows scripts to programmatically open, resize, and reposition various types of windows. Often, disreputable Web sites will resize windows to either hide other windows or force you to interact with a window that contains malicious code. The Scripted Window Security Restrictions security feature restricts pop-up windows and prohibits scripts from displaying windows in which the title and status bars are not visible to the user or hide other windows’ title and status bars. If you enable the Scripted Window Security Restrictions\Internet Explorer Processes policy setting, pop-up windows and other restrictions apply for Windows Explorer and Internet Explorer processes. If you disable or do not configure this policy setting, scripts can continue to create pop-up windows and windows that hide other windows. This appendix recommends you configure this setting to Enabled to help prevent malicious Web sites from controlling your Internet Explorer windows or fooling users into clicking on the wrong window.
