28、ervedForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through t

29、echnical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take

30、 part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare I

31、nternational Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. In exceptional circumstances, when the joint

32、 technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art“, for example), it may decide to publish a Technical Report. A Technical Report is entirely informative in nature and shall be subject to review every fiv

33、e years in the same manner as an International Standard. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC TR 27019 was prepared by DIN

34、 Deutsches Institut fr Normung e. V. (as DIN SPEC 27009:2012-04 4) and was adopted, under a special “fast-track procedure“, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by the national bodies of ISO and IEC.

35、ll rights reserved viiIntroduction This Technical Report provides guiding principles based on ISO/IEC 27002 “Code of practice for information security management” for information security management applied to process control systems as used in the energy utility industry. The aim of this document i

36、s to extend the ISO/IEC 27000 standards to the domain of process control systems and automation technology, thus allowing the energy utility industry to implement a standardized information security management system (ISMS) in accordance with ISO/IEC 27001 that extends from the business to the proce

37、ss control level. At the focus of application of this document are the systems and networks for controlling and supervising the generation, transmission and distribution of electric power, gas and heat in combination with the control of facilitating processes. This includes control and automation sy

38、stems, protection and safety systems and measurement systems, including their associated communications and telecontrol applications. For purposes of simplification, these systems will be collectively referred to in the following as “process control systems”. In addition to the security objectives a

39、nd measures that are set forth in ISO/IEC 27002:2005, the process control systems used by energy utilities and energy suppliers are subject to further, special requirements. In comparison with conventional IT environments (e.g. office IT) there are fundamental and significant differences with respec

40、t to the development, operation, repair, maintenance and operating environment of process control systems. Furthermore, the process technology referred to in this document may represent integral components of critical infrastructures which means they are therefore essential for the secure and reliab

41、le operation of such infrastructures. These distinctions and characteristics need to be taken into due consideration by the management processes for process control systems and justify separate consideration within the ISO/IEC 27000 series of standards. In particular, the following fundamental diffe

42、rences exist compared with conventional IT systems: Security features In comparison with conventional IT systems, process control systems exhibit increased requirements with regard to their availability and integrity. In some operational environments failure of the process monitoring and control sys

43、tems cannot be tolerated. Also, the integrity of the data processed is frequently of crucial importance. Incorrect data can lead to incorrect control inputs, resulting in failure of protection or safety systems or trigger incorrect decisions by operating personnel, as a result of an erroneous repres

44、entation of current process conditions. These requirements therefore need to be taken into consideration during the system design stage as well as in normal operation. System architecture Besides the central IT installations within control centers for grid operation or conventional power plants ther

45、e are several systems which are typically distributed over larger areas, e.g.: process control and monitoring systems within substations and gas pressure regulating and metering stations; process control and monitoring systems for distributed generation, like wind-farms or photovoltaic generation un

46、its; digital metering and measurement devices. ISO/IEC TR 27019:2013(E) viii ISO/IEC 2013 All rights reservedOften, these remote systems cannot be physically protected at the same level as centrally located systems. Therefore, the system architecture needs to take these differences into consideratio

47、n and it may be necessary to provide additional safeguards at the interface between distributed and central systems. Also, the operating and management processes for distributed systems may vary in comparison with centralized IT architectures. It is for instance, not normal procedure to apply change

48、s to essential systems in critical substations or at other important sites via remote access, unless the corresponding field service personnel are present on-site. Furthermore, in many process control environments the architecture should allow for autonomous (local) operation of each distributed sit

49、e without network access to central installations. In case of outages it has to be possible to restart selected sites without an external energy source, e.g. for grid restoration (“black start capable” systems). Maintenance Process control systems are often designed for a service life of 20 or more years. If standard operating systems or software packages are used, special measures to handle outdated and no-longer supported software are needed. Frequent shutdowns of process control components, e.g. to install software pa
