(Amendment)Security for industrial automation and control systems - Part 2-4: Security program requirements for IACS service providers (IEC 62443-2-4:2015/A1:2017)
Security for industrial automation and control systems - Part 2-4: Security program requirements for IACS service providers (IEC 62443-2-4:2015/A1:2017)
This part of IEC 62443 specifies a comprehensive set of requirements for security capabilities
for IACS service providers that they can offer to the asset owner during integration and
maintenance activities of an Automation Solution. Because not all requirements apply to all
industry groups and organizations, Subclause 4.1.4 provides for the development of Profiles
that allow for the subsetting of these requirements. Profiles are used to adapt this document
to specific environments, including environments not based on an IACS.
NOTE 1 The term “Automation Solution” is used as a proper noun (and therefore capitalized) in this part of
IEC 62443 to prevent confusion with other uses of this term.
Collectively, the security capabilities offered by an IACS service provider are referred to as its
Security Program. In a related specification, IEC 62443-2-1 describes requirements for the
Security Management System of the asset owner.
NOTE 2 In general, these security capabilities are policy, procedure, practice and personnel related.
Figure 2 illustrates how the integration and maintenance capabilities relate to the IACS and
the control system product that is integrated into the Automation Solution. Some of these
capabilities reference security measures defined in IEC 62443-3-3 that the service provider
must ensure are supported in the Automation Solution (either included in the control system
product or separately added to the Automation Solution).

Zaščita industrijske avtomatizacije in nadzornih sistemov - 2-4. del: Zahteve za program zaščite za ponudnike storitev IACS - Dopolnilo A1 (IEC 62443-2-4:2015/A1:2017)
Ta del standarda IEC 62443 določa izčrpen sklop zahtev za zmogljivosti zaščite
za ponudnike storitev IACS, ki jih lahko ponudijo lastniku dobrine med integracijo in
vzdrževanjem Rešitve avtomatizacije. Ker vse zahteve ne veljajo za vse
industrijske skupine in organizacije, podtočka 4.1.4 zagotavlja razvoj profilov, ki
omogočajo podnabor teh zahtev. Profili se uporabljajo za prilagoditev tega dokumenta
posebnim okoljem, vključno z okolji, ki ne temeljijo na skupnosti IACS.
OPOMBA 1: Izraz »Rešitev avtomatizacije« se v tem delu standarda IEC 62443 uporablja kot lastno ime (in je zato zapisan z veliko začetnico), da ga ni mogoče zamenjati z drugimi uporabami tega izraza.
Skupaj se zmogljivosti zaščite, ki jih ponuja ponudnik storitev IACS, imenujejo njegov
program varnosti zaščite. V povezani specifikaciji standard IEC 62443-2-1 opisuje zahteve za
sistem vodenja zaščite lastnika dobrine.
OPOMBA 2: Na splošno so te zmogljivosti zaščite povezane s politiko, postopki, prakso in osebjem.
Na sliki 2 je prikazano, kako so zmogljivosti integracije in vzdrževanja povezane s skupnostjo IACS in
izdelkom nadzornega sistema, ki je integriran v Rešitev avtomatizacije. Nekatere od teh
zmogljivosti se navezujejo na ukrepe za zaščito iz standarda IEC 62443-3-3, za katere mora ponudnik storitev
zagotoviti, da jih Rešitev avtomatizacije podpira (so vključeni v izdelku nadzornega
sistema ali pa so v Rešitev avtomatizacije dodani posebej).

_____________
1 Scope
Replace the first paragraph by the following new text:
This part of IEC 62443 specifies a comprehensive set of requirements for security capabilities
for IACS service providers that they can offer to the asset owner during integration and
maintenance activities of an Automation Solution. Because not all requirements apply to all
industry groups and organizations, Subclause 4.1.4 provides for the development of Profiles
that allow for the subsetting of these requirements. Profiles are used to adapt this document
to specific environments, including environments not based on an IACS.
Delete Note 4 and renumber Note 5 to "Note 4".
3.1.14
safety instrumented system
Add the following Note 2 to entry:
Note 2 to entry: Not all industry sectors use this term. This term is not restricted to any specific industry sector,
and it is used generically to refer to systems that enforce functional safety. Other equivalent terms include safety
systems and safety related systems.
4.1.4 Profiles
Replace the existing text with the following:
This document recognizes that not all of the requirements in Annex A apply to all industry
sectors/environments. To allow subsetting and adaptation of these requirements, this
document provides for the use of “Profiles”.
IEC 62443-2-4:2015/AMD 1:2017 – 3 –
© 2017
Profiles are written as IEC Technical Reports (TRs) by industry groups/sectors or other
organizations, including asset owners and service providers, to select/adapt Annex A
requirements that are most appropriate to their specific needs.
Each TR may define one or more profiles, and each profile identifies a subset of the
requirements defined in Annex A and specifies, where necessary, how specific requirements
are to be applied in the environment where they are to be used.
It is anticipated that asset owners will select these profiles to specify the requirements that
apply to their Automation Solutions.
4.2 Maturity model
Table 1 – Maturity levels
Replace, in the fourth column, row for Level 2, the second paragraph that begins with “At this
level, the service provider has…” by the following:
At this level, the service provider has the capability to manage the delivery and performance of the service
according to written policies (including objectives). The service provider also has evidence to show that personnel
who will perform the service have the expertise, are trained, and/or are capable of following written procedures to
perform the service.
5.1 Contents
Insert the following new paragraph between the first paragraph and the note:
Not all requirements apply to all service providers, and asset owners may request service
providers to perform only a subset of the required capabilities specified in Annex A. In
addition, industry sectors, service providers, and asset owners may define their own profiles
that contain a subset of these requirements (see 4.1.4).
5.3 IEC 62264-1 hierarchy model
Replace the first paragraph with the following:
Many of the requirements in Annex A refer to network or application levels in phrases such as
“a wireless handheld device is used in Level 2”. When capitalized, “Level” in this context
refers to the position in the IEC 62264-1 Hierarchy Model. The Level of a referenced object
(e.g. wireless handheld device) is represented by the lowest Level function that it executes.
The zones and conduits model described by IEC 62443-3-2 is referenced by requirements in
Annex A that address, independent of the IEC 62264-1 Hierarchy Model Level, trust
boundaries that subdivide the Automation Solution into partitions referred to as “zones” by
IEC 62443-3-2.
