      Endpoint Security Posture Assessment - Enterprise Use Cases
                      draft-ietf-sacm-use-cases-03

Abstract

   This memo documents a sampling of use cases for securely aggregating
   configuration and operational data and evaluating that data to
   determine an organization's security posture.  From these operational
   use cases, we can derive common functional capabilities and
   requirements to guide development of vendor-neutral, interoperable
   standards for aggregating and evaluating data relevant to security
   posture.
