Table of Contents

1. Introduction

Our goal with this document is to improve our agreement on the terminology used in documents produced by the IETF Working Group for Security Automation and Continuous Monitoring. Agreeing on terminology should help reach consensus on which problems we're trying to solve, and propose solutions and decide which ones to use.

This document is expected to be a temporary work product, and will probably be incorporated into the architecture or other document.

2. Terms and Definitions

This section describes terms that have been defined by other RFC's and defines new ones. The predefined terms will reference the RFC and where appropriate will be annotated with the specific context by which the term is used in SACM.

2.1. Pre-defined Terms





Information Model


Posture Attributes

System Resource

2.2. New Terms and Definitions

This section defines terms that are not explictly defined in the IETF.

Asset characterization

Asset Management

Asset Targeting

Building Block

Collection Task

Evaluation Task

Endpoint Target

Endpoint Discovery

Evaluation Result

Expected Endpoint State

Security Automation

2.3. Requirements Language

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].

3. IANA Considerations

This memo includes no request to IANA.

4. Security Considerations

This memo documents terminology for security automation. While it is about security, it does not affect security.

6. Change Log

6.1. ietf-sacm-terminology-01- to -02-

Added simple list of terms extracted from UC draft -05. It is expected that comments will be received on this list of terms as to whether they should be kept in this document. Those that are kept will be appropriately defined or cited.

6.2. ietf-sacm-terminology-01- to -02-

Added Vulnerability, Vulnerability Management, xposure, Misconfiguration, and Software flaw.

6.3. ietf-sacm-terminology-02- to -03-

Removed Section 2.1. Cleaned up some editing nits; broke terms into 2 sections (predefined and newly defined terms). Added some of the relevant terms per the proposed list discussed in the IETF 89 meeting.
