Industrial communication networks - Network and system security - Part 3-3: System security requirements and security levels

This part of the IEC 62443 series provides detailed technical control system requirements (SRs) associated with the seven foundational requirements (FRs) described in IEC 62443‑1‑1 including defining the requirements for control system capability security levels, SL-C(control system). These requirements would be used by various members of the industrial automation and control system (IACS) community along with the defined zones and conduits for the system under consideration (SuC) while developing the appropriate control system target SL, SL-T(control system), for a specific asset. As defined in IEC 62443‑1‑1 there are a total of seven FRs: a) Identification and authentication control (IAC), b) Use control (UC), c) System integrity (SI), d) Data confidentiality (DC), e) Restricted data flow (RDF), f) Timely response to events (TRE), and g) Resource availability (RA). These seven requirements are the foundation for control system capability SLs, SL-C (control system). Defining security capability at the control system level is the goal and objective of this standard as opposed to target SLs, SL-T, or achieved SLs, SL-A, which are out of scope. See IEC 62443‑2‑1 for an equivalent set of non-technical, program-related, capability SRs necessary for fully achieving a control system target SL.

Réseaux industriels de communication - Sécurité dans les réseaux et les systèmes - Partie-3: Exigences relatives à la sécurité dans les systèmes et niveaux de sécurité

IEC 62443-3-3:2013 fournit des exigences système (SR) de commande techniques détaillées associées aux sept exigences fondamentales (FR) décrites dans l’IEC 62443‑1‑1, y compris la définition des exigences des niveaux de sécurité de capacité du système de commande, SL C (système de commande). Ces exigences sont utilisées par plusieurs membres de la communauté des systèmes d’automatisation et de commande industrielles (IACS) ainsi que les zones et conduits définis pour le système à l'étude (SuC), tout en développant le SL cible du système de commande approprié, SL-T (système de commande) pour un actif spécifique. Le contenu du corrigendum d’avril 2014 est inclus dans la présente copie.

Industrijska komunikacijska omrežja - Zaščita omrežja in sistema - 3-3. del: Zahteve za zaščito in nivoje varnosti sistemov (IEC 62443-3-3:2013)

Ta del skupine standardov IEC 62443 podaja podrobne tehnične zahteve za nadzorne sisteme (SR), ki so povezane s sedmimi temeljnimi zahtevami (FR), opisanimi v standardu IEC 62443 1 1, vključno z določanjem zahtev za nivoje varnosti zmogljivosti nadzornega sistema, SL-C (nadzorni sistem). Te zahteve bodo uporabljali različni člani skupnosti industrijske avtomatizacije in nadzornih sistemov (IACS) poleg opredeljenih con in vodov za obravnavani sistem (SuC) pri razvijanju ustreznih ciljnih nivojev varnosti nadzornega sistema, SL-T (nadzorni sistem), za določeno dobrino.
Kot je opredeljeno v standardu IEC 62443 1 1, obstaja sedem temeljnih zahtev:
a) nadzor identifikacije in preverjanja pristnosti (IAC),
b) nadzor uporabe (UC),
c) celovitost sistema (SI),
d) zaupnost podatkov (DC),
e) omejen pretok podatkov (RDF),
f) pravočasen odziv na dogodke (TRE) in
g) razpoložljivost virov (RA).
Teh sedem zahtev so temelj za nivoje varnosti zmogljivosti nadzornega sistema, SL-C (nadzorni sistem). Opredelitev zmogljivosti zaščite na ravni nadzornega sistema je cilj tega standarda v nasprotju s ciljnimi nivoji varnosti, SL-T, ali doseženimi nivoji varnosti, SL-A, ki niso zajeti.
Glej standard IEC 62443 2 1 za enakovreden nabor netehničnih, s programom povezanih zahtev za sistem, ki so potrebne za v celoti dosežene ciljne nivoje varnosti nadzornega sistema.
