Security
Last updated 1/14/2015
• You want an organization-wide security solution for PDFs. You can devise a solution specifically for a company
handling sensitive data. Some organizations use Adobe LiveCycle Rights Management ES to apply a policy to
documents. The policy contains the list of recipients and their individual set of permissions. Individuals can use a
policy to apply the same security settings to numerous documents. (See
Securing documents with Adobe LiveCycle
Rights Management ES .)
Security policies
A security policy enforces systematic constraints on information flow and exchange within an organization. You can
use Adobe LiveCycleRights Management ES to apply a policy to documents without the need for digital signatures and
certificates. If you often apply the same security settings to PDFs, consider creating a security policy to simplify your
workflow. Different policies are useful for accommodating different requirements.
Envelope policy You can secure multiple documents by embedding them in a PDF envelope. You can encrypt
envelopes to prevent unauthorized users from accessing the contents and certify them to provide proof of origin.
Authorized recipients can open the envelope and extract the files to view them.
LiveCycle Rights Management ES policy Adobe LiveCycleRights Management ES policies are stored on a server, and
users must have access to the server to use them. Creating these policies requires specifying the document recipients
from a list on Adobe LiveCycleRights Management ES.
Password and certificate policies Save your password or certificate settings and reuse them to encrypt PDFs without
setting up the password or certificate for each instance.
If you apply security settings to a PDF Portfolio in Acrobat Pro, including the component documents, you can automate
the steps by using Action Wizard (Choose File >Action Wizard).
