Information technology — Open Trusted Technology ProviderTM Standard (O-TTPS) — Part 2: Assessment procedures for the O-TTPS
ISO/IEC 20243-2:2018 specifies the procedures to be utilized by an assessor when conducting a conformity assessment to the mandatory requirements in the Open Trusted Technology Provider? Standard (O-TTPS).1 These Assessment Procedures are intended to ensure the repeatability, reproducibility, and objectivity of assessments against the O-TTPS. Though the primary audience for this document is the assessor, an Information Technology (IT) provider who is undergoing assessment or preparing for assessment, may also find this document useful.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed
for the different types of document should be noted (see www.iso.org/directives or
www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had
not received notice of (a) patent(s) which may be required to implement this document. However,
implementers are cautioned that this may not represent the latest information, which may be obtained
from the patent database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall
not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the World
Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by The Open Group [as Open Trusted Technology Provider Standard
(O-TTPS) V1.2, Part 2: Assessment Procedures for the O-TTPS] and drafted in accordance with its
editorial rules. It was adopted, under the JTC 1 PAS procedure, by Joint Technical Committee
ISO/IEC JTC 1, Information technology.
This second edition cancels and replaces the first edition (ISO/IEC 20243-2:2018), which has been
technically revised.
The main changes are as follows:
— Wording has been changed throughout the document, including in introductory materials, attribute
definitions and requirements, as necessary to improve clarity and/or concision.
— The definition of “component” has been clarified to include both hardware and software.
— A definition for “security-critical” has been added.
— PD_DES.01 has become a mandatory requirement.
— PD_CFM.04 has become a mandatory requirement.
— The attribute definition of PD_QAT has been clarified.
— The attribute definition of PD_PSM has been clarified.

— The SE_VAR requirements have been largely reworked and reorganized, with a new mandatory
requirement being added and several existing requirements becoming mandatory.
— SE_PPR.02 has become a mandatory requirement.
— SE_PPR.04 has become a mandatory requirement.
— SC_RSM.05 has become a mandatory requirement.
— SC_ACC.04 has become a mandatory requirement.

The Open Group publishes a wide range of technical documentation, most of which is focused on
development of Standards and Guides, but which also includes white papers, technical studies,
certification and testing documentation, and business titles. Full details and a catalog are available at
www.opengroup.org/library.
This Document
The Open Group Open Trusted Technology Forum (OTTF) is a global initiative that invites industry,
government, and other interested participants to work together to evolve the O-TTPS and other OTTF
deliverables.
This document is Part 2 of the Open Trusted Technology Provider Standard (O-TTPS). It has been
developed by the OTTF and approved by The Open Group, through The Open Group Company Review
process. There are two distinct elements that should be understood with respect to this document: the
O-TTPF (Framework) and the O-TTPS (Standard).
The O-TTPF (Framework): The O-TTPF is an evolving compendium of organizational guidelines and
best practices relating to the integrity of Commercial Off-The-Shelf (COTS) Information and
Communications Technology (ICT) products and the security of the supply chain throughout the entire
product lifecycle.
An early version of the O-TTPF was published as a White Paper in February 2011, revised in November
2015, and has since been updated and published as a Guide in September 2021 (see Referenced
Documents). The O-TTPF serves as the basis for the O-TTPS, future updates, and additional standards.
