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.
