In talking about PDF security, it is important to distinguish between these two concepts. Standard Acrobat security refers to the security measures that can be applied by Acrobat itself. These can either be applied directly from within the Acrobat interface, or with 3rd party applications or plug-ins. These features allow document authors to restrict access and editing of their PDF documents or forms, and are sufficient for many users.

If you need more control over your content, then you may need to implement a more advanced Digital Rights Management (DRM) solution. DRM systems help protect the copyright of materials by defining how the content can be used. The rights are determined by the publishers. For example, FileOpen Publisher allows publishers to lock documents to a hard disk or CD-ROM, limit printing or set them to expire after a preset time, while FileOpen WebPublisher adds the ability to manage user rights in real time.

Some documents must be further controlled by having sensitive content permanently removed in order to make them suitable for consumption. This process is known as "redaction" and can be accomplished with Appligent's Redax.
