Mac OS X: PDF Files Require User Password for Print Security

When adding document security features to an Adobe portable document format (PDF) document, always assign a user password to the document to ensure the effectiveness of the security.
Symptom

PDF documents designed to have additional security features, such as not allowing printing, but without a user password assigned to them are not necessarily secure.


Solution

Add a user password to all secure documents.

The only way to ensure a PDF document with security features is always secure and cannot be modified is to add a user password. Any PDF document without a user password should not be used in situations where the security features need to be enforced.
