15、 DATA AND COMMUNICATIONS SECURITY Part 13: Guidelines on security topics to be covered in standards and specifications FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Com

16、mittees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Avai

17、lable Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental o

18、rganizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technic

19、al matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC

20、National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformi

21、ty, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC

22、 itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure t

23、hat they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any n

24、ature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referen

25、ced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main

26、 task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a Technical Report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“.

27、 IEC TR 62351-13, which is a Technical Report, has been prepared by IEC technical committee 57: Power systems management and associated information exchange. PD IEC/TR 62351-13:2016IEC TR 62351-13:2016 IEC 2016 5 The text of this Technical Report is based on the following documents: Enquiry draft Re

28、port on voting 57/1678/DTR 57/1727/RVC Full information on the voting for the approval of this Technical Report can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62351

29、 series, published under the general title Power systems management and associated information exchange Data and communications security, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the I

30、EC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo o

32、nt provides guidelines on what security topics should be covered in standards and specifications (IEC or otherwise) that are to be used in the power industry. These guidelines cannot be prescriptive for every standard, since individual standards and specifications may legitimately have very differen

33、t focuses, but it should be expected that the combination of such standards and specifications used in any implementation should cover these security topics. These guidelines could therefore be used as a checklist for the combination of standards and specifications used in implementations of systems

34、. The security requirements for human users and software applications are different from the purely technical security requirements found in many communication and device standards. For user security standards, more emphasis should be on “policy and procedures” and “roles and authorization” rather t

35、han “bits and bytes” cryptographic technologies that should be included in Information and Communications Technology (ICT). In addition, engineering practices and system configurations should be taken into account, since no cryptography can compensate for poor design. Figure 1 illustrates the relati

36、onships between security requirements, threats, and attacks. This document is structured into four sections: Clause 5: Security requirements for standards and specifications which do not address specific cybersecurity technologies but where interactions between human users, software applications, an

37、d smart devices should be secured. Clause 6: Security requirements for standards and specifications that address information and communication technologies (ICT). Clause 7: Engineering design and configuration requirements that provide system reliability, defence in depth, and other security threat

38、mitigations. Clause 8: Security requirements related to the OSI reference model.
