The emerging need to connect the Department of Agriculture network to other government agencies, private companies and other organizations using Internet Protocol (IP) demands a coordinated and uniform approach to implementing secure IP connectivity.  A characteristic of an interconnected environment is the ability to easily share resources and information.  From a business perspective, this is a desirable feature, with hidden threats.  Unfortunately the inherent nature of an interconnected architecture also results in sharing risks.  A risk to one system becomes a risk to all systems.
