   Security Automation and Continuous Monitoring (SACM) Architecture
                        draft-ietf-sacm-arch-07

Abstract

   This document defines an architecture enabling a cooperative Security
   Automation and Continuous Monitoring (SACM) ecosystem.  This work is
   predicated upon information gleaned from SACM Use Cases and
   Requirements ([RFC7632] and [RFC8248] respectively), and terminology
   as found in [I-D.ietf-sacm-terminology].

   WORKING GROUP: The source for this draft is maintained in GitHub.
   Suggested changes should be submitted as pull requests at
   https://github.com/sacmwg/ietf-mandm-sacm-arch/.  Instructions are on
   that page as well.
