Adobe Systems announced the availability of the Adobe LifeCycle Policy Server, which company officials say provides the strongest and most versatile security controls Adobe has ever delivered for determining who can open or modify PDF documents. The LifeCycle Policy Server is tightly integrated with Adobe Acrobat 7.0 and the Adobe Reader 7.0, which Adobe also officially released to the market this week. The LifeCycle Policy Server is a J2EE (Java 2 Enterprise Edition) application that runs on most widely used platforms, including Windows, Linux and the Macintosh.
