Software Defined Perimeter

Overview
The Software Defined Perimeter (SDP) initiative by the Cloud Security Alliance aims to make "invisible networks" accessible to a wider range of government agencies and corporations. The initiative will foster development of an architecture for securing the Internet of Things by using the cloud to create highly secure end-to-end networks between any IP-addressable entities.
