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 temorary work product, and will
   probably be incorporated into the architecture or other document.

2.  Terms and Definitions

   assessment

      Defined in [RFC5209] as "the process of collecting posture for a
      set of capabilities on the endpoint (e.g., host-based firewall)
      such that the appropriate validators may evaluate the posture
      against compliance policy."

      Within this document the use of the term is expanded to support
      other uses of collected posture (e.g. reporting, network
      enforcement, vulnerability detection, license management).  The
      phrase "set of capabilities on the endpoint" includes: hardware
      and software installed on the endpoint."

   asset

      Defined in [RFC4949] as "a system resource that is (a) required to
      be protected by an information system's security policy, (b)
      intended to be protect by a countermeasure, or (c) required for a
      system's mission.

Internet-Draft     Terminology for Security Assessment       August 2013


   attribute

      Defined in [RFC5209] as "data element including any requisite
      meta-data describing an observed, expected, or the operational
      status of an endpoint feature (e.g., anti-virus software is
      currently in use)."

   endpoint

      Defined in [RFC5209] as "any computing device that can be
      connected to a network.  Such devices normally are associated with
      a particular link layer address before joining the network and
      potentially an IP address once on the network.  This includes:
      laptops, desktops, servers, cell phones, or any device that may
      have an IP address."

      Network infrastructure devices (e.g. switches, routers,
      firewalls), which fit the definition, are also considered to be
      endpoints within this document.

      Based on the previous definition of an asset, an endpoint is a
      type of asset.

   posture

      Defined in [RFC5209] as "configuration and/or status of hardware
      or software on an endpoint as it pertains to an organization's
      security policy."

      This term is used within the scope of this document to represent
      the state information that is collected from an endpoint (e.g.
      software/hardware inventory, configuration settings).

   posture attributes

      Defined in [RFC5209] as "attributes describing the configuration
      or status (posture) of a feature of the endpoint.  For example, a
      Posture Attribute might describe the version of the operating
      system installed on the system."

      Within this document this term represents a specific assertion
      about endpoint state (e.g. configuration setting, installed
      software, hardware).  The phrase "features of the endpoint" refers
      to installed software or software components.

   system resource

Internet-Draft     Terminology for Security Assessment       August 2013


      Defined in [RFC4949] as "data contained in an information system;
      or a service provided by a system; or a system capacity, such as
      processing power or communication bandwidth; or an item of system
      equipment (i.e., hardware, firmware, software, or documentation);
      or a facility that houses system operations and equipment.

2.1.  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.
