Chapter 1 What’s New for FortiOS 5.2.1 : Top Features : Unified Policy Management
  
Unified Policy Management
The different creation pages in the web-based manager for policy types and subtypes (user-identity, device identity, and VPN) have been merged into a single main policy creation page. New fields have been added for Source User(s) and Source Device Type that remove the need for multiple authentication rules in a single police. This allows for greater control and customization of policies, as a combination of these source types can be used in a single policy rather than having to pick one type.
