(Main)Security for industrial automation and control systems - Part 2-1: Security program requirements for IACS asset owners
Security for industrial automation and control systems - Part 2-1: Security program requirements for IACS asset owners
IEC 62443-2-1:2024 specifies asset owner security program (SP) policy and procedure requirements for an industrial automation and control system (IACS) in operation. This document uses the broad definition and scope of what constitutes an IACS as described in IEC TS 62443‑1‑1. In the context of this document, asset owner also includes the operator of the IACS. This document recognizes that the lifespan of an IACS can exceed twenty years, and that many legacy systems contain hardware and software that are no longer supported. Therefore, the SP for most legacy systems addresses only a subset of the requirements defined in this document. For example, if IACS or component software is no longer supported, security patching requirements cannot be met. Similarly, backup software for many older systems is not available for all components of the IACS. This document does not specify that an IACS has these technical requirements. This document states that the asset owner needs to have policies and procedures around these types of requirements. In the case where an asset owner has legacy systems that do not have the native technical capabilities, compensating security measures can be part of the policies and procedures specified in this document. This edition includes the following significant technical changes with respect to the previous edition: a) revised requirement structure into SP elements (SPEs), b) revised requirements to eliminate duplication of an information security management system (ISMS), and c) defined a maturity model for evaluating requirements.
IT-Sicherheit für industrielle Automatisierungssysteme - Teil 2-1: Anforderungen an ein IT-Sicherheitsprogramm für IACS-Betreiber
Sécurité des systèmes d’automatisation et de commande industrielles - Partie 2-1: Exigences de programme de sécurité pour les propriétaires d’actif IACS
IEC 62443-2-1:2024 spécifie les exigences de politiques et de procédures du programme de sécurité (SP) du propriétaire d’actif pour un système d’automatisation et de commande industrielle (IACS) opérationnel. Le présent document utilise, au sens large, la définition et le domaine d’application de ce qui constitue un IACS décrit dans l’IEC TS 62443‑1-1. Dans le contexte du présent document, le propriétaire d’actif inclut également l’opérateur de l’IACS. Le présent document reconnaît que la durée de vie d’un IACS peut dépasser vingt ans et que de nombreux systèmes patrimoniaux contiennent du matériel et du logiciel qui ne sont plus pris en charge. Par conséquent, le SP de la plupart des systèmes patrimoniaux ne concerne qu’un sous-ensemble des exigences définies dans le présent document. Les exigences en matière de correctifs de sécurité, par exemple, ne peuvent pas être satisfaites si l’IACS ou le logiciel composant n’est plus pris en charge. De même, le logiciel de sauvegarde de la plupart des systèmes plus anciens n’est pas disponible pour tous les composants de l’IACS. Le présent document ne précise pas qu'un IACS doit satisfaire à ces exigences techniques. Il indique qu’il est nécessaire que le propriétaire d’actif dispose de politiques et de procédures relatives à ces types d'exigences. Dans le cas où le propriétaire d'actif possède des systèmes patrimoniaux qui ne comportent pas des capacités techniques natives, des mesures de sécurité compensatoires peuvent faire partie des politiques et procédures spécifiées dans le présent document. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) la structure des exigences a été révisée en éléments SP (SPE – SP element); b) les exigences ont été révisées pour éliminer la répétition d'un système de management de la sécurité de l'information (SMSI); et c) un modèle de stabilisation a été défini pour l'évaluation des exigences.
