NIST had a Continuous Monitoring (CM) workshop several months ago to solicit feedback and discuss a technical reference model, as described in draft Internal Report (IR) 7756: An Enterprise Continuous Monitoring Technical Reference Architecture.
The outcome was for NIST to propose technical workflows, subsystems, interfaces, and bindings to SCAP (asset, configuration, and vulnerability management).
NIST has just announced that the requested content is ready for review. They have setup weekly meetings for Thursdays at 10 am Pacific, starting August 18th with a general model discussion. A specific workflow or subsystem will be the subject of each following meeting. Details for the meetings will be communicated to the Emerging Specification Development List. The results of these meetings will be presented at the 7th IT Security Automation Conference.
