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 contentimages, linked media, data connections and templatesto 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 criteriavalid and current digital signature, and reputable certificateto 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 ( New! ), which allows it to run without being checked by the Trust Center.

Setting Add-in Security Options

An add-in, such as smart tags, extends functionality to Microsoft Office programs ( New! ). An add-in can add buttons and custom commands to the Ribbon. When an add-in is installed, it appears on the Add-Ins tab of an Office program and includes a special ScreenTip that identifies the developer. Since add-ins are software code added to Microsoft Office programs, hackers can use them to do malicious harm, such as spreading a virus. The Trust Center uses a set of criteriavalid and current digital signature, reputable certificate and a trusted publisherto make sure add-ins are safe and secure. If it discovers a potentially unsafe add-in, it disables the code and notifies you in the Message Bar. If the add-in security options are not set to the level you need, you can change them in the Trust Center.
