    Secure Automation and Continuous Monitoring (SACM) Architecture
                    draft-ietf-sacm-architecture-02

Abstract

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

1.  Introduction

   Several data models and protocols 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
