Security for industrial automation and control systems - Part 4-1: Secure product development lifecycle requirements

IEC 62443-4:2018(E) specifies the process requirements for the secure development of products used in industrial automation and control systems. This specification is part of a series of standards that addresses the issue of security for industrial automation and control systems (IACS). IEC 62443-4 defines secure development life-cycle (SDL) requirements related to cyber security for products intended for use in the industrial automation and control systems environment and provides guidance on how to meet the requirements described for each element. The life-cycle description includes security requirements definition, secure design, secure implementation (including coding guidelines), verification and validation, defect management, patch management and product end-of-life. These requirements can be applied to new or existing processes for developing, maintaining and retiring hardware, software or firmware. Note that these requirements only apply to the developer and maintainer of the product, and are not applicable to the integrator or the user of the product. A summary list of the requirements is provided in Annex B.

IT-Sicherheit für industrielle Automatisierungssysteme - Teil 4-1: Anforderungen an den Lebenszyklus für eine sichere Produktentwicklung

Sécurité des automatismes industriels et des systèmes de commande - Partie 4-1 : Exigences applicables au cycle de vie de développement sécurisé des produits

L'IEC 62443-4:2018 spécifie les exigences relatives au processus de développement sécurisé des produits utilisés dans des systèmes d'automatisation et de commande industriels. Elle définit un cycle de développement sécurisé (SDL – secure development life-cycle) en vue de développer et d'assurer la sécurité des produits. Ce cycle inclut la définition des exigences de sécurité, la conception sécurisée, la mise en œuvre sécurisée (y compris les lignes directrices en matière de codage), la vérification et la validation, la gestion des défauts, la gestion des correctifs et la fin de vie du produit. Ces exigences peuvent être appliquées à des processus nouveaux ou existants pour le développement, la maintenance et le retrait des matériels, logiciels et micrologiciels destinés aux produits nouveaux ou existants. Elles s'appliquent au développeur et au chargé de maintenance du produit, mais pas à l'intégrateur ni à l'utilisateur du produit. Une liste récapitulative des exigences du présent document peut être consultée à l'Annexe B.

Zaščita industrijske avtomatizacije in nadzornih sistemov - 4-1. del: Zahteve za varnost izdelka v obdobju razvoja izdelka (IEC 62443-4-1:2018)

Ta del standarda IEC 62443 določa postopkovne zahteve za varnost izdelkov v obdobju razvoja, uporabljene pri industrijski avtomatizaciji in kontrolnih sistemih. Opredeljuje varnost izdelkov v obdobju razvoja (SDL) za razvoj in ohranjanje varnosti izdelkov. To obdobje vključuje opredelitev varnostnih zahtev, varno zasnovo, varno implementacijo (vključno s smernicami glede kodiranja), preverjanje in potrjevanje, upravljanje napak, upravljanje popravkov in ravnanje ob koncu življenjske dobe izdelka. Te zahteve veljajo za nove in obstoječe postopke za razvoj, vzdrževanje in umik strojne opreme, programske opreme ali vdelane programske opreme za nove ali obstoječe izdelke. Te zahteve veljajo za razvijalca ali vzdrževalca izdelka, ne pa tudi za integratorja ali uporabnika izdelka. Zbirni seznam zahtev v tem dokumentov je mogoče najti v dodatku B.
