InPrivate Filtering
You probably know that the Web sites you visit can track your activity, but you may not be fully aware of
the degree to which additional Web sites and content providers can track you as well. Most Web sites
today are mosaics of content that come from many different sites. As a result, the sites you visit often pull
in content from third-party sites, which can track your activity even though you’re not aware of it. There
are many security risks inherent in this model—you can be exposed to potentially malicious content from
every third-party site that is referenced.
InPrivate Filtering in Internet Explorer 8 is designed
to protect your privacy by helping prevent infor-
mation about the Web sites that you visit from
automatically being shared with other sites. It works
by observing the Web sites you visit and building a
table of the unique calls for third-party content or
objects that are observed for each unique domain.
When InPrivate Filtering is active, it blocks third-
party content based on the default threshold of 10
unique such observances.
Data Execution Prevention
Some Internet-based threats—such as a virus disguised as a picture—exploit certain types of memory-
related vulnerabilities. Data Execution Prevention helps prevent code that resides in memory space
marked as nonexecutable from running. This security feature works silently in the background, helping to
protect against viruses and malware being installed on your PC without your knowledge.
Tab Isolation and Crash Recovery
Have you ever been in the middle of lling out a long form on a Web site when the browser crashed, forc-
ing you to start over? In Internet Explorer 8, if a tab does crash, it is automatically restored and reloaded,
and any information you may have already entered on the page (such as writing an e-mail or lling out
a form) is restored. Similarly, if the entire browser crashes or closes unexpectedly, Internet Explorer 8
restores the entire session (including all tabs).
InPrivate Filtering is designed
to protect your privacy.
