Assessment Title

Rule Text

Userdata persistence must be disallowed (Internet zone).

Description

Discussion Text

Userdata persistence must have level of protection based upon the site being accessed. It is possible for sites hosting malicious content to exploit this feature as part of an attack against visitors browsing the site. This policy setting allows you to manage the preservation of information in the browser's history, in favorites, in an XML store, or directly within a web page saved to disk. When a user returns to a persisted page, the state of the page can be restored if this policy setting is not appropriately configured.
