This Document
The Open Group Trusted Technology Forum (OTTF or Forum) is a global initiative that invites
industry, government, and other interested participants to work together to evolve this Standard
and other OTTF deliverables.
This Standard is the Open Trusted Technology Provider Standard (O-TTPS). The Standard 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 Standard: the O-TTPF (Framework) and the O-TTPS (Standard).
The O-TTPF (Framework): The Framework is an evolving compendium of organizational
guidelines and best practices relating to the integrity of Commercial Off-the-Shelf (COTS)
Information and Communication Technology (ICT) products and the security of the supply chain
throughout the entire product life cycle. An early version of the Framework was published as a
White Paper in February 2011 (see Referenced Documents). The Framework serves as the basis
for this Standard, future updates, and additional standards. The content of the Framework is the
result of industry collaboration and research as to those commonly used commercially

reasonable practices that increase product integrity and supply chain security. The members of
the OTTF will continue to collaborate with industry and governments and update the Framework
as the threat landscape changes and industry practices evolve.
The O-TTPS (Standard): The O-TTPS is an open standard containing a set of guidelines that
when properly adhered to have been shown to enhance the security of the global supply chain
and the integrity of COTS ICT products. It provides a set of guidelines, requirements, and
recommendations that help assure against maliciously tainted and counterfeit products
throughout the COTS ICT product life cycle encompassing the following phases: design,
sourcing, build, fulfillment, distribution, sustainment, and disposal.
Using the guidelines documented in the Framework as a basis, the OTTF is taking a phased
approach and staging O-TTPS releases over time. This staging will consist of standards that
focus on mitigating specific COTS ICT risks from emerging threats. As threats change or market
needs evolve, the OTTF intends to update the O-TTPS (Standard) by releasing addenda to
address specific threats or market needs.
The Standard is aimed at enhancing the integrity of COTS ICT products and helping customers
to manage sourcing risk. The authors of this Standard recognize the value that it can bring to
governments and commercial customers worldwide, particularly those who adopt procurement
and sourcing strategies that reward those vendors who follow the O-TTPS best practice
requirements and recommendations.
Note: Any reference to “providers” is intended to refer to COTS ICT providers. The use of
the word “component” is intended to refer to either hardware or software components.
Intended Audience
This Standard is intended for organizations interested in helping the industry evolve to meet the
threats in the delivery of trustworthy COTS ICT products. It is intended to provide enough
context and information on business drivers to enable its audience to understand the value in
adopting the guidelines, requirements, and recommendations specified within. It also allows
providers, suppliers, and integrators to begin planning how to implement the Standard in their
organizations. Additionally, acquirers and customers can begin recommending the adoption of
the Standard to their providers and integrators.

1 Introduction
This chapter introduces this Standard – the Open Trusted Technology Provider Standard (O-
TTPS) – and the normative terminology that should be understood in relation to specific
requirements and recommendations found in Chapter 4 of this document.
1.1 Objectives
The Open Trusted Technology Provider Standard (O-TTPS) is a set of guidelines, requirements,
and recommendations that, when practically applied, create a business benefit in terms of
reduced risk of acquiring maliciously tainted or counterfeit products for the technology acquirer.
Documenting best practices that have been taken from the experience of mature industry
providers, rigorously reviewed through a consensus process, and established as requirements and
recommendations in this Standard, can provide significant advantage in establishing a basis to
reduce risk. A commitment by technology providers, large and small, suppliers of hardware and
software components, and integrators to adopt this Standard is a commitment to using specific
methodologies to assure the integrity of their hardware or software Commercial Off-the-Shelf
(COTS) Information and Communication Technology (ICT) products. This Standard is detailed
and prescriptive enough to be useful in raising the bar for all providers and lends itself to an
accreditation process to provide assurance that it is being followed in a meaningful and
repeatable manner.
1.2 Overview
This Standard (O-TTPS) is a set of guidelines, requirements, and recommendations that address
specific threats to the integrity of hardware and software COTS ICT products throughout the
product life cycle. This initial release of the Standard addresses threats related to maliciously
tainted and counterfeit products.
The provider’s product life cycle includes the work it does designing and developing products,
as well as the supply chain aspects of that life cycle, collectively extending through the
following phases: design, sourcing, build, fulfillment, distribution, sustainment, and disposal.
While this Standard cannot fully address threats that originate wholly outside any span of control
of the provider – for example, a counterfeiter producing a fake printed circuit board assembly
that has no original linkage to the Original Equipment Manufacturer (OEM) – the practices
detailed in the Standard will provide some level of mitigation. An example of such a practice
would be the use of security labeling techniques in legitimate products.
The two major threats that acquirers face today in their COTS ICT procurements, as addressed in
this Standard, are defined as:
1. Maliciously tainted product – the product is produced by the provider and is acquired
through a provider’s authorized channel, but has been tampered with maliciously.
™
Open Trusted Technology Provider Standard (O-TTPS), Version 1.1 1

---------------------- Page: 13 ----------------------
ISO/IEC 20243:2015(E)
2. Counterfeit product – the product is produced other than by, or for, the provider, or is
supplied to the provider by other than a provider’s authorized channel and is presented as
being legitimate even though it is not.
Note: All instances, within this standard, of the use of the words: taint, tainted, tainting, refer
to maliciously taint, maliciously tainted, and maliciously tainting, respectively.
Trusted Technology Providers manage their product life cycle, including their extended supply
chains, through the application of defined, monitored, and validated best practices. The product’s
integrity is strengthened when providers and suppliers follow the requirements and
recommendations specified in this Standard. The industry consensus reflected here and in the
Open Trusted Technology Provider Framework (O-TTPF) draws from the following areas that
are integral to product integrity: product development/engineering, secure
development/engineering, and supply chain security. Additionally, product integrity and supply
chain security are enhanced by following practices among suppliers, trading partners, providers,
and, when appropriate, acquiring customers to preserve the product’s intended configuration.
This Standard is focused on the security of the supply chain versus the business management
aspects of the supply chain. This Standard takes a comprehensive view about what providers
should do in order to be considered a Trusted Technology Provider that “builds with integrity”.
This includes practices that providers incorporate in their own internal product life cycle
processes, that portion of product development that is “in-house” and over which they have more
direct operational control. Additionally, it includes the provider’s supply chain security practices
that need to be followed when incorporating third-party hardware or software components, or
when depending on external manufacturing and delivery or supportive services.
The Standard makes a distinction between provider and supplier. Suppliers are those upstream
vendors who supply components or solutions (software or hardware) to providers or integrators.
Providers are those vendors who supply COTS ICT products directly to the downstream
integrator or acquirer.
Ideally, the guidelines, requirements, and recommendations included in this Standard will be
widely adopted by providers and their suppliers regardless of size and will provide benefits
throughout the industry.
For this version of the Standard, the following elements are considered out of scope:
This Standard does not focus on guidelines, requirements, and recommendations for the
acquirer. The Forum is considering addressing this area in subsequent versions of the
Standard. In the meantime, an acquirer does have a role to play in assuring that the
products and components they procure are built with integrity. One of the ways that the
acquirer can do that is to require their providers, suppliers, and integrators to be Trusted
Technology Providers. Another way is to not knowingly support the “grey market”,
realizing that if an acquirer elects to receive hardware or software support from grey
market suppliers, it is at their own risk and generally outside of the influence of the
legitimate provider.
This Standard is not meant to be comprehensive as to all practices that a provider should
follow when building software or hardware. For a more comprehensive set of foundational

ISO/IEC 20243:2015(E)
best practices that a provider could implement to produce good quality products, readers
can refer to the O-TTPF White Paper.
This version of the Standard does not apply to the operation or hosting infrastructure of
on-line services, but can apply to COTS ICT products in as far as they are utilized by
those services.
This Standard complements existing standards covering product security functionality and
product information assurance, such as ISO/IEC 15408 (Common Criteria).
1.3 Conformance
The OTTF intends to develop conformance criteria and create an Accreditation Policy and
Program for the Open Trusted Technology Provider Standard (O-TTPS) as a useful tool for all
constituents with an interest in supply chain security. Without the associated conformance
criteria and an Accreditation Program, there is no assurance that an organization has
implemented practices according to the O-TTPS.
Accreditation will provide formal recognition of conformance to the O-TTPS, which allows:
Providers and practitioners to make and substantiate clear claims of conformance to the
Standard
Acquirers to specify and successfully procure from providers who conform to the
Standard
Conformance assessment is the act of determining the conformance of an implementation to a
specification, or the adherence of a business operation to a best practice or process definition.
There are many techniques for assessing such conformance, including the use of a standardized
test method, quality assessment by industry experts or third-party test laboratories, and vendors’
claims of conformance made within a defined legal framework.
The O-TTPS accreditation process, conformance criteria, conformance assessment, policies,
parties, and their roles will be defined and approved after the publication of Version 1.0 of this
Standard.
1.4 Terminology
This section provides a set of terms and their definitions, which should be used when describing
and interpreting the Standard requirements and recommendations specified in Chapter 4 of this
Standard. These terms are aligned with ISO/IEC Directives, Part 2 (Annex H).
Shall Indicates an absolute, mandatory requirement of the Standard that has to be
implemented in order to conform to the Standard and from which no
deviation is permitted. Do not use “must” as an alternative for “shall”. (This
will avoid any confusion between the requirements of a document and
external statutory obligations.)

---------------------- Page: 15 ----------------------
ISO/IEC 20243:2015(E)
Shall not Indicates an absolute preclusion of the Standard, and if implemented would
represent a non-conformity with the Standard. Do not use “may not” instead
of “shall not” to express a prohibition.
Should Indicates a recommendation among several possibilities that is particularly
suitable, without mentioning or excluding others, or that a certain course of
action is preferred but not necessarily required.
Should not Indicates a practice explicitly recommended not to be implemented, or that a
certain possibility or course of action is deprecated but not prohibited. To
conform to the Standard, an acceptable justification must be presented if the
requirement is implemented.
May Indicates an optional requirement to be implemented at the discretion of the
practitioner. Do not use “can” instead of “may” in this context.
Can Used for statements of possibility and capability, whether material, physical,
or causal.
1.5 Future Directions
The OTTF intends to address possible additional threats and risks with best practice
requirements and recommendations in future Standard releases. The OTTF also intends to
provide conformance criteria and an O-TTPS Accreditation Program.

2 Business Context and Overview
This chapter describes the typical business environment, the business rationale, the context of
Commercial Off-the-Shelf (COTS) Information and Communication Technology (ICT), and an
overview of the Open Trusted Technology Provider Framework (O-TTPF) and this Open
Trusted Technology Provider Standard (O-TTPS).
2.1 Business Environment Summary
Globalization is inherent in the business environment. The rapid pace of globalization has
brought both benefits and risks to customers of COTS ICT products. Globalization is an
essential factor in the ability to build, deliver, and support feature-rich COTS ICT hardware and
software, and the economies of scale resulting from globalization are a significant benefit. In
fact, in today’s market COTS ICT products could not exist without global development – the
global production environment is essential to the technology industry.
As cyber attacks increase in sophistication, stealth, and severity, global governments and larger
enterprises have also begun to take a more comprehensive approach to risk management as it
applies to product integrity and supply chain security. In addition to enhancing information
security by improving security practices across the enterprise, governments and enterprises have
begun inquiring about the practices COTS ICT vendors use to protect the integrity of their
products and services as they are developed and moved through the global supply chain. First,
one needs to understand the extent of the global supply chain by looking at an operational
scenario.
