Specify privileged locations for trusted content
Enhanced security provides a way to specify locations for trusted content. These privileged locations can be single files,
folders, or host domains (root URLs). Content that resides in a privileged location is trusted. For example, enhanced
security normally blocks PDFs from loading data from unknown websites. If you add the data’s origin (its host
domain) to your list of privileged locations, Acrobat and Reader allow loading the data. For details, see the Enhanced
Security document at
www.adobe.com/go/learn_acr_appsecurity_en.
1 Select Edit > Preferences (Windows) or Acrobat/Adobe Reader > Preferences (Mac OS).
2 From the Categories on the left, select Security (Enhanced).
3 Select the Enable Enhanced Security option.
4 Specify a list of locations in the Privileged Locations section, and then click OK.
• To trust any sites you already trust in Internet Explorer, select Automatically Trust Sites From My Win OS Security
Zones.
• To add only one or two PDFs from a location, click Add File.
• To create a trusted folder for multiple PDFS, click Add Folder Path.
• To allow data to load from a website, enter the name of the root URL. For example, enter www.adobe.com, but not
www.adobe.com/products. To trust files from secure connections only, select Secure Connections Only (https:).
Protected View (Windows only)
Protected View provides an additional level of security. When Protected View in enabled, PDFs are displayed in a
restricted environment called a sandbox. This isolation of the PDFs reduces the risk of security breaches in areas
outside the sandbox. Adobe strongly recommends that you use Acrobat in Protected View if you are concerned about
security, or if you frequently interact with PDFs on the Internet.
Note: Adobe Reader includes a similar restricted environment called Protected Mode. For information about Reader
Protected Mode, see Reader Help.
When Protected View is enabled, only basic navigation is allowed. For example, you can open PDFs, scroll through
pages, and click links. You can enable Protected View in a PDF that you view in either stand-alone Acrobat or in a web
browser.
PDF in stand-alone Acrobat In Protected View, Acrobat displays a warning for a PDF that doesn’t originate from a
trusted location. The warning lets you decide whether to trust the document.
If you trust the PDF and where it came from, click Enable All Features. The PDF is added to your list of privileged locations and is trusted from
then on.
PDF in a web browser A PDF in Protected View functions the same in a browser as a Reader-extended PDF that is
viewed in Reader. The warning does not appear in the browser.
You can find out whether a PDF opened in a browser is in Protected View. Right-click the document in the browser
and choose Document Properties. Click the Advanced tab. When Protected View is enabled, the status says Protected
Mode: On.
