Security for industrial automation and control systems - Part 2-4: Security program requirements for IACS service providers (IEC 62443-2-4:2023)
IEC 62443-2:2023 specifies a comprehensive set of requirements for security-related processes that IACS service providers 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 document to prevent confusion with other uses of this term. Collectively, the security processes offered by an IACS service provider are referred to as its Security Program (SP) for IACS asset owners. 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 1 illustrates the integration and maintenance security processes of the asset owner, service provider(s), and product supplier(s) of an IACS and their relationships to each other and to the Automation Solution. Some of the requirements of this document relating to the safety program are associated with security requirements described in IEC 62443-3-3 and IEC 62443-4-2.
NOTE 3 The IACS is a combination of the Automation Solution and the organizational measures necessary for its design, deployment, operation, and maintenance.
NOTE 4 Maintenance of legacy system with insufficient security technical capabilities, implementation of policies, processes and procedures can be addressed through risk mitigation.

Zaščita industrijske avtomatizacije in nadzornih sistemov - 2-4. del: Zahteve za program zaščite za ponudnike storitev IACS (IEC 62443-2-4:2023)
Standard IEC 62443-2:2023 določa izčrpen sklop zahtev za procese v zvezi z zaščito, ki jih lahko ponudniki storitev IACS zagotavljajo lastniku sredstva 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 storitvah IACS.
OPOMBA 1: Izraz »rešitev avtomatizacije« se v tem dokumentu uporablja kot lastno ime (in je zato zapisan z veliko začetnico), da ga ni mogoče zamenjati z drugimi uporabami tega izraza. Skupaj se procesi zaščite, ki jih zagotavlja ponudnik storitev IACS, imenujejo njegov program zaščite (SP) za lastnike sredstev IACS. V povezani specifikaciji standard IEC 62443-2-1 opisuje zahteve za sistem upravljanja zaščite lastnika sredstva.
OPOMBA 2: Na splošno so te zmogljivosti zaščite povezane s politiko, postopki, prakso in osebjem. Slika 1 prikazuje procese zaščite, ki jih v okviru integracije in vzdrževanja izvajajo lastnik sredstva, ponudnik(-i) storitve in dobavitelj(-i) storitve IACS, ter njihova razmerja med seboj in do rešitve avtomatizacije. Nekatere zahteve v tem dokumentu, ki se navezujejo na program zaščite, so povezane z zahtevami glede zaščite iz standardov IEC 62443-3-3 in IEC 62443-4-2.
OPOMBA 3: IACS je kombinacija rešitve avtomatizacije in organizacijskih ukrepov, potrebnih za njeno načrtovanje, uvedbo, delovanje in vzdrževanje.
OPOMBA 4: K vzdrževanju starejšega sistema z nezadostno tehnično zmogljivostjo na področju zaščite ter izvajanju pravilnikov, procesov in postopkov je mogoče pristopiti z zmanjšanjem tveganja.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes 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, 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, wh
