Selecting Trusted Publishers and Locations
The
Trust Center security system continually checks for external
potentially unsafe content in your documents. Hackers can hide Web
beacons in external content—images, linked media, data connections and
templates—to gather information about you or cause problems. When the
Trust Center detects potentially harmful external content, the Message
Bar appears with a security alert and options to enable or block the
content. Trusted publishers are reputable developers who create
application extensions, such as a macro, ActiveX control, or add-in. The
Trust Center uses a set of criteria—valid and current digital
signature, and reputable certificate—to make sure publishers’ code and
source locations are safe and secure. If you are sure that the external
content is trustworthy, you can add the content publisher and location
to your trusted lists, which allows it to run without being checked by
the Trust Center.

Setting Document Related Security Options
The
Trust Center security system allows you to set file-related options to
check for potentially unsafe content in your documents (New!). In Trusted Documents (New!),
you can set options to open trusted documents without any security
prompts for macros, ActiveX controls and other types of active content
in the document. For a trusted document, you won’t be prompted the next
time you open the document even if new active content was added to the
document or changes were made to existing active content. You should
only trust documents if you trust the source. Protected view (New!)
provides a place to open potentially dangerous files, without any
security prompts, in a restricted mode to help minimize harm to your
computer. If you disable Protected view, you could expose your computer
to possible harmful threats. In File Block Settings (New!),
you can select the Open and Save check boxes to prevent each file type
from opening, or just opening in Protected view, and from saving.
