    Secure Automation and Continuous Monitoring (SACM) Architecture
                    draft-ietf-sacm-architecture-04

Abstract

   This document defines an architecture for standardization of
   interfaces, protocols, and information models related to security
   automation and continuous monitoring.  It describes the basic
   architecture, components, and interfaces defined to enable the
   collection, acquisition, and verification of Posture and Posture
   Assessments.

1.  Introduction

   Several data models and protocols (including - but not limited to -
   NEA, TCG TNC, SCAP, SWIDs, XMPP, etc.) are in use today that allow
   different applications to perform the collection, acquisition, and
   assessment of posture.  These applications can vary from being
   focused on general system and security management to specialized
   configuration, compliance, and control systems.  With an existing
   varied set of applications, there is a strong desire to standardize
