EN IEC 62351-4:2018

Power systems management and associated information exchange - Data and communications security - Part 4: Profiles including MMS and derivatives

1.1 General This part of IEC 62351 extends the scope of IEC TS 62351-4:2007 [1]1 by specifying a compatibility mode that provides interoperation with implementation based on IEC TS 62351- 4:2007 and by specifying extended capabilities referred to as native mode. This part of IEC 62351 specifies security requirements both at the transport layer and at the application layer. While IEC TS 62351-4:2007 primarily provided some limited support at the application layer for authentication during handshake for the Manufacturing Message Specification (MMS) based applications, this document also provides support for extended integrity and authentication both for the handshake phase and for the data transfer phase. It provides for shared key management and data transfer encryption at the application layer and it provides security end-to-end (E2E) with zero or more intermediate entities. While IEC TS 62351-4:2007 only provides support for systems based on the MMS, i.e. systems using an Open Systems Interworking (OSI) protocol stack, this document also provides support for application protocols using other protocol stacks, e.g. an Internet protocol suite (see 4.1). This support is extended to protect application protocols using XML encoding. This extended security at the application layer is referred to as E2E-security. In addition to E2E security, this part of IEC 62351 also provides mapping to environmental protocols carrying the security related information. Only OSI and XMPP environments are currently considered. It is intended that this part of IEC 62351 be referenced as a normative part of standards that have a need for using application protocols, e.g., MMS, in a secure manner. It is anticipated that there are implementations, in particular Inter-Control Centre Communications Protocol (ICCP) implementations that are dependent on the IEC TS 62351- 4:2007 specifications of the T-profile and the A-security-profile. The specifications from IEC TS 62351-4:2007 are therefore included in this part of IEC 62351. Implementations supporting these specifications will interwork with implementation based on IEC TS 62351-4:2007. NOTE The A-security-profile is in the strict sense not a profile, but the term is here kept for historical reasons. This document represents a set of mandatory and optional security specifications to be implemented to protect application protocols. The initial audience for this document is the members of the working groups developing or making use of protocols. For the measures described in this part of IEC 62351 to take effect, they shall be accepted and referenced by the specifications for the protocols themselves. The subsequent audience for this document is the developers of products that implement these protocols and the end user that want to specify requirements for its own environment. Portions of this document may also be of use to managers and executives in order to understand the purpose and requirements of the work.

Energiemanagementsysteme und zugehöriger Datenaustausch - IT-Sicherheit für Daten und Kommunikation - Teil 4: Profile einschließlich MMS und Ableitungen

Gestion des systèmes de puissance et échanges d'informations associés - Sécurité des communications et des données - Partie 4 : Profils comprenant MMS

IEC 62351:2018 spécifie les exigences de sécurité concernant à la fois la couche transport et la couche application. Alors que l’IEC TS 62351-4:2007 apportait principalement une aide limitée concernant la couche application pour l’authentification lors de l’établissement de liaison des applications fondées sur la messagerie MMS (manufacturing message specification), le présent document fournit également une assistance quant à l’extension de l’intégrité et l’authentification lors des phases d’établissement de liaison et de transfert de données. Il pourvoit à la gestion essentielle partagée et au chiffrement de transfert de données pour la couche application et assure la sécurité bout-à-bout (E2E - end-to-end) avec zéro entité intermédiaire ou plus. Alors que l’IEC TS 62351-4:2007 apporte une assistance uniquement pour les systèmes fondés sur la MMS, c’est-à-dire les systèmes utilisant une pile de protocoles OSI (open systems interworking - interconnexion de systèmes ouverts), le présent document fournit également une assistance quant aux protocoles d’application utilisant d’autres piles de protocoles, par exemple une suite de protocoles Internet (voir 4.1). Cette assistance est étendue afin d’assurer la protection des protocoles d’application utilisant le codage XML. Cette sécurité étendue au niveau de la couche application est appelée sécurité E2E. En plus de la sécurité E2E, la présente partie de l’IEC 62351 présente également la mise en correspondance avec les protocoles environnementaux comportant les informations concernant la sécurité. Seuls les environnements OSI et XMPP sont actuellement pris en considération.

Upravljanje elektroenergetskega sistema in pripadajoča izmenjava informacij - Varnost podatkov in komunikacij - 4. del: Profili, vključno z MMS in izpeljankami

Ta del standarda IEC 62351 razširja področje uporabe standarda IEC TS 62351-4:2007 [1]1, saj določa način združljivosti, ki zagotavlja interoperabilnost z izvajanjem na podlagi standarda IEC TS 62351-4:2007 in določa razširjene zmogljivosti, imenovane nativni način.
Ta del standarda IEC 62351 določa varnostne zahteve tako na transportni kot na aplikacijski plasti. Medtem ko je IEC TS 62351-4:2007 primarno zagotovil omejeno podporo na aplikacijski plasti za preverjanje pristnosti med rokovanjem z aplikacijami na osnovi MMS (Manufacturing Message Specification), pa ta dokument zagotavlja tudi podporo za razširjeno integriteto in preverjanje pristnosti tako za fazo rokovanja kot za fazo prenosa podatkov. Zagotavlja upravljanje s ključem v skupni rabi, šifriranje prenosa podatkov na aplikacijski plasti in celostno varnost (E2E) z nič ali več vmesnimi enotami. Medtem ko IEC TS 62351-4:2007 zagotavlja podporo samo za sisteme na osnovi MMS, tj. sisteme, ki uporabljajo sklad protokolov OSI (Open Systems Interworking), pa ta dokument zagotavlja tudi podporo za aplikacijske protokole, ki uporabljajo druge sklade protokolov, npr. zbirko internetnih protokolov (glej 4.1)
Ta podpora je razširjena za zaščito aplikacijskih protokolov s kodiranjem XML. Ta razširjena varnost na aplikacijski plasti se imenuje E2E-varnost.
Poleg E2E-varnosti zagotavlja ta del standarda IEC 62351 tudi preslikavo v okoljske protokole, ki vsebujejo informacije v zvezi z varnostjo. Trenutno so obravnavana samo okolja OSI in XMPP.
Ta del standarda IEC 62351 naj bi bil normativni del standardov, v katerih je zahtevana varna uporaba aplikacijskih protokolov, npr. MMS.
Predvidoma obstajajo izvedbe, zlasti izvedbe komunikacijskega protokola ICCP (Inter-Control Centre Communications Protocol), ki so odvisne od specifikacij T-profila in A-varnostnega profila iz standarda IEC TS 62351- 4:2007. Specifikacije iz standarda IEC TS 62351-4:2007 so zato vključene v ta del standarda IEC 62351. Izvedbe, ki podpirajo te specifikacije, se bodo lahko povezovale z izvedbami na podlagi standarda IEC TS 62351-4:2007.
OPOMBA: A-varnostni profil v strogem pomenu besede ni profil, ampak je izraz, ohranjen zaradi zgodovinskih razlogov.
Ta dokument predstavlja niz obveznih in neobveznih varnostnih specifikacij, ki jih je treba uporabiti za zaščito aplikacijskih protokolov.
Namembni uporabniki tega dokumenta so člani delovnih skupin, ki razvijajo ali uporabljajo protokole. Ukrepi, opisani v tem delu standarda IEC 62351, stopijo v veljavo, ko so sprejeti in sklicevani v samih specifikacijah protokolov.
Drugi uporabniki tega dokumenta so lahko tudi razvijalci izdelkov, ki uvajajo te protokole, in končni uporabnik, ki želi določiti zahteve za lastno okolje.
Deli tega dokumenta lahko pomagajo tudi direktorjem in vodjem pri razumevanju namena in zahtev dela.
