With Protected Mode enabled, all PDF file operations will run in a restricted manner inside a confined environment, the “sandbox”. It is similar to the Google Chrome sandbox and Microsoft Office 2010 Protected Viewing Mode. Protected Mode is a sandboxing technology based on Microsoft’s Practical Windows Sandboxing technique.
Adobe had announced the upcoming version of their Acrobat Family of Products last month with a new feature that provides better security via “Protected mode.” This feature is enabled by default in Adobe Reader X.
