Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
Internet, digital services and technology are important enablers for smart manufacturing, which is one
part of internet of things (IoT) (see ISO/IEC 20924). For the manufacturing environment, the foundations
are vertical networking and horizontal integration across the entire value chain, convergence of
design, ordering, delivery and manufacturing capabilities. This results in the transformation of
conventional value chains and the emergence of new business models. Smart products based on smart
manufacturing know many details on how they were made, their performance and how they are being
used. The physical product is linked to its digital representation, and the digital content depends on
lifecycle phase. Implementing smart manufacturing creates an efficient and highly responsive package
by leveraging existing manufacturing systems, as well as technological and economic potential. Smart
manufacturing increases the vulnerabilities of machinery to IT-security threats.
Smart manufacturing leads to the emergence of dynamic, real-time optimized, self-organizing value
chains. An appropriate regulatory framework is therefore necessary, as well as standardized interfaces
and harmonized business processes. Smart manufacturing is characterized by:
a) increased product flexibility;
b) new intrinsic built-in product properties;
c) flexible work organization;
d) changed scale (up to a lot size 1) and location of manufacturing.
For smart manufacturing, the description of the network infrastructure needs to be further expanded
to enable privacy, self-configuration and ease of use. Therefore, there is a need for fast available, robust
and secure communication networks.
The primary purpose of this document is to address aspects on safety of machinery that can be
affected by IT-security attacks related to the direct or remote access to, and manipulation of, a safety-
related control system(s) by persons for intentional abuse (unintended uses). IT-security attacks are
increasingly becoming a potential threat to the safety of machinery. Although intentional abuse falls
outside the scope of ISO 12100 and the (safety-related) risk assessment process, it is reasonable also for
machinery manufacturers to consider such threats.
Current technologies enable machinery to be monitored and/or improved regarding their performance
remotely by adjusting parameters without having to be on site at the machine. This ability provides
considerable benefits as machinery can be kept operating without the downtime and associated costs
of a field service person making a service call.
However, this same capability to adjust machine parameters to improve performance lends itself to the
possibility for persons with nefarious or criminal intent to make adjustments that can put workers and
others at risk of harm. For example, speeds or forces can be adjusted to dangerous levels, temperatures
can be lowered below a kill step level resulting in food contamination, or error codes or messages c
