Enabling Enhanced Security - Adobe 22002486 User Manual

Acrobat 9 Family of Products
Security Feature User Guide
Enhanced Security interacts with the Trust Manager so that the most permissive setting takes

precedence. For example, if a document is signed with a certificate that's trusted for an action that
Enhanced Security would normally prevent, that action will be allowed.

9.1.1 Enabling Enhanced Security

This feature is only available to Acrobat users. Enhanced security is designed to limit document behaviors
in workflows where those behaviors are perceived as a vulnerability or security risk. In workflows where
security is critical, users can turn this feature on. Administrators can also configure the application for
enhanced security and lock down the setting so it can't be changed by the user.
Control of the following behaviors at the file, folder, and host level:

Cross-domain data access: Different origin data downloads (from where the current PDF resides)

to the PDF.
Data injection: Injection of the data into the document; most notably into form fields via JavaScript

or into the document and application via FDF files. Note that FDF files are used specifically to
transport data and that turning on enhanced security will impair FDF's ability to do that.
External streams access: Access to external XObjects; that is, references to objects such as images

that reside outside the PDF.
Script injection: Injection and execution of JavaScript.

Silent printing: Printing initiated by JavaScript or other document-based methods without user

interaction. This includes printing to a file on disk and is not restricted to hardware printers.
Weblink: Connecting to the web.

To turn on Enhanced Security and specify privileged locations, do the following:
1. Choose Edit > Preferences > Security (Enhanced).
2. Check the Enable Enhanced Security checkbox.
3. (Optional) Set a privileged location by selecting one or more of the following buttons:
Note:
Add File: Select this option if you only have one or two files from a location that you want to add. If

you have a large number of files you know you can trust, it can be more practical to place them into
one privileged folder.
Add Folder Path: If you have a large number of files that you trust, specify an entire directory.

Add Host: Enter the name of the root URL only. For example, enter www.adobe.com but not www.

adobe.com/products. To only allow higher privileges for files accessed from secure connections,
select the option for Secure Connections Only (https:).
4. Choose OK.
Privileged locations bypass Enhanced Security restrictions.
