Using Security Policies
Often, you find that you are repeating the same sequence of actions to apply consistent security settings to a
series of documents or projects. Rather than manually applying the certificate or password to the document,
create a security policy instead. You can build security policies for passwords, certificates, or Adobe Policy
Server; the discussion is limited to passwords and certificates.
Creating a Password Security Policy
Password protection is commonly used to prevent changes in documents distributed anonymously, such as
content intended for Web site use.
