Endpoint Security Posture Assessment: Enterprise Use Cases
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.

RFC 7632 Enterprise Use Cases for Sec Assessment September 2015
1. Introduction
This document describes the core set of use cases for endpoint
posture assessment for enterprises. It provides a discussion of
these use cases and associated building-block capabilities. The
described use cases support:
o securely collecting and aggregating configuration and operational
data, and
o evaluating that data to determine the security posture of
individual endpoints.
Additionally, this document describes a set of usage scenarios that
provide examples for using the use cases and associated building
blocks to address a variety of operational functions.
These operational use cases and related usage scenarios cross many IT
security domains. The use cases enable the derivation of common:
o concepts that are expressed as building blocks in this document,
