16、al 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 technical committees established by the respective organization to deal with particular fields o
17、f 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 part in the work. In the field of information technology, ISO and IEC have established a joint
18、 technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of document should be noted. This document wa
19、s drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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
20、such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and

23、SO/IEC 27050-1:2016(E) Introduction This document provides an overview of electronic discovery and describes related terminology, concepts, and processes that are intended to be leveraged by other parts of ISO/IEC 27050. Electronic discovery often serves as a driver for investigations as well as evi
24、dence acquisition and handling activities (covered in ISO/IEC 27037). In addition, the sensitivity and criticality of the data sometimes necessitate protections like storage security to guard against data breaches (covered in ISO/IEC 27040). This document is not a reference or normative document for
25、 regulatory and legislative security requirements. Although it emphasizes the importance of these influences, it cannot state them specifically, since they are dependent on the country, the type of business, etc.vi ISO/IEC 2016 All rights reservedBS ISO/IEC 27050-1:2016Information technology Securit
26、y techniques Electronic discovery Part 1: Overview and concepts 1 Scope Electronic discovery is the process of discovering pertinent Electronically Stored Information (ESI) or data by one or more parties involved in an investigation or litigation, or similar proceeding. This document provides an ove
27、rview of electronic discovery. In addition, it defines related terms and describes the concepts, including, but not limited to, identification, preservation, collection, processing, review, analysis, and production of ESI. This document also identifies other relevant standards (e.g. ISO/IEC 27037) a
28、nd how they relate to, and interact with, electronic discovery activities. This document is relevant to both non-technical and technical personnel involved in some or all of the electronic discovery activities, and it is not intended to contradict or supersede local jurisdictional laws and regulatio
29、ns, so exercise care to ensure compliance with the prevailing jurisdictional requirements. 2 Normative references There are no normative references in this document. 3 T erms a nd definiti ons For the purposes of this document, the terms and definitions given in ISO/IEC 27000 and the following apply

33、 information held by another party or non-party concerning a matter Note 1 to entry: Discovery is applicable more broadly than to parties in adversarial disputes. Note 2 to entry: Discovery is also the disclosure of hardcopy documents, Electronically Stored Information (3.9) and tangible objects by
34、an adverse party. Note 3 to entry: In some jurisdictions, the term disclosure is used interchangeably with discovery. 3.5 disposition range of processes associated with implementing records retention, destruction or transfer decisions which are documented in disposition authorities (3.6) or other in
