Security for industrial automation and control systems - Part 2-4: Security program requirements for IACS service providers (IEC 62443-2-4:2015)

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).

Sécurité des automatismes industriels et des systèmes de commande – Partie 2-4: Exigences de programme de sécurité pour les fournisseurs de service IACS (IEC 62443-2-4:2015)

L'IEC 62443-2-4:2015 spécifie les exigences de capacités de sécurité pour les fournisseurs de service IACS qu'ils peuvent proposer au propriétaire d'actif pendant les activités d'intégration et de maintenance d'une Solution d'Automatisation.
Le contenu du corrigendum d'août 2015 a été pris en considération dans cet exemplaire.

Zaščita industrijske avtomatizacije in nadzornih sistemov - 2-4. del: Zahteve za program varnosti zaščite za ponudnike storitev IACS (IEC 62443-2-4:2015)

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).

SECURITY FOR INDUSTRIAL AUTOMATION
AND CONTROL SYSTEMS –
Part 2-4: Security program requirements
for IACS service providers
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62443-2-4 has been prepared by IEC technical committee 65:
Industrial-process measurement, control and automation.
This publication contains an attached file in the form of an Excel 97-2003 spreadsheet version

Part 2-4: Security program requirements
for IACS service providers
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62443-2-4 has been prepared by IEC technical committee 65:
Industrial-process measurement, control and automation.
This publication contains an attached file in the form of an Excel 97-2003 spreadsheet version
of Table A.1. This file is intended to be used as a complement and does not form an integral
part of the publication.
