With the release of the 10.1 update, Acrobat X for Windows provides a sandbox called Protected View. Protected View is another defense-in-depth feature that is tightly integrated with the existing Enhanced Security feature. Protected View in Acrobat leverages the successful sandbox implementation already in place for Adobe Reader while providing a user experience that should be familiar to Microsoft Office 2010 users.

Acrobat’s Protected View sandbox is similar to Reader’s Protected Mode sandbox and provides equal protection. Just like Reader, Acrobat strictly confines the execution environment of untrusted PDF files and the processes they invoke. Based on user preferences when Protected View is enabled, Acrobat assumes either all PDF files or just PDF files loading from untrusted locations are potentially malicious and confines processing to a restricted sandbox.
