'''IEC 62351''' is a standard developed by WG15 of [[International Electrotechnical Commission|IEC]] [[IEC TC 57|TC57]]. This is developed for handling the security of TC 57 series of protocols including [[IEC 60870-5]] series, [[IEC 60870-6]] series, [[IEC 61850]] series, [[IEC 61970]] series & [[IEC 61968]] series. The different security objectives include authentication of data transfer through [[digital signatures]], ensuring only authenticated access, prevention of [[eavesdropping]], prevention of playback and [[Spoofing attack|spoofing]], and [[Intrusion detection system|intrusion detection]].

==Standard details==
* ''IEC 62351-1'' — Introduction to the standard
* ''IEC 62351-2'' — Glossary of terms
* ''IEC 62351-3 Ed. 2'' — Security for any profiles including [[TCP/IP]]. Current edition was published 06/2023, replacing edition 1.2.
** [[Transport Layer Security|TLS]] Encryption
** Node Authentication by means of [[X.509|X.509 certificates]]
** Message Authentication
* ''IEC 62351-4'' — Security for any profiles including [[Manufacturing Message Specification|MMS]] (e.g., ICCP-based [[IEC 60870-6]], [[IEC 61850]], etc.).
** Authentication for MMS
** TLS (RFC 2246)is inserted between RFC 1006 & RFC 793 to provide transport layer security
* ''IEC 62351-5'' — Security for any profiles including [[IEC 60870-5]] (e.g., [[DNP3]] derivative)
** TLS for TCP/IP profiles and encryption for serial profiles.
* ''IEC 62351-6'' — Security for [[IEC 61850]] profiles.
** [[VLAN]] use is made as mandatory for [[GOOSE]]
** RFC 2030 to be used for SNTP
* ''IEC 62351-7'' — Security through network and system management.
** Defines [[Management Information Base]] (MIBs) that are specific for the power industry, to handle network and system management through [[SNMP]] based methods.
* ''IEC 62351-8'' — Role-based access control.
** Covers the access control of users and automated agents to data objects in power systems by means of role-based access control ([[RBAC]]).
* ''IEC 62351-9'' — Key Management
** Describes the correct and safe usage of safety-critical parameters, e.g. passwords, encryption keys.
** Covers the whole life cycle of cryptographic information (enrollment, creation, distribution, installation, usage, storage and removal).
** Methods for algorithms using asymmetric cryptography
*** Handling of [[Public_key_certificate|digital certificates ]] (public / private key)
*** Setup of the [[Public_key_infrastructure|PKI]] environment with [[X.509|X.509 certificates]]
*** Certificate enrollment by means of [[Simple_Certificate_Enrollment_Protocol|SCEP]] / [[Enrollment over Secure Transport|EST]], while allowing the use of other enrollment protocols
*** [[Certificate revocation]] by means of [[Revocation_list|CRL]] / [[Online_Certificate_Status_Protocol|OCSP]]
** A secure distribution mechanism based on [[Group_Domain_of_Interpretation|GDOI]] and the [[Internet_Key_Exchange|IKEv1]] protocol is presented for the usage of symmetric keys, e.g. session keys.
* ''IEC 62351-10'' — Security Architecture
** Explanation of security architectures for the entire IT infrastructure
** Identifying critical points of the communication architecture, e.g. substation control center, substation automation
** Appropriate mechanisms security requirements, e.g. data encryption, user authentication
** Applicability of well-proven standards from the IT domain, e.g. VPN tunnel, secure FTP, HTTPS
* ''IEC 62351-11'' — Security for XML Files
** Embedding of the original XML content into an XML container
** Date of issue and access control for XML data
** X.509 signature for authenticity of XML data
** Optional data encryption
