35、his International Standard is concerned with providing assurance that the investigative process used is appropriate for the incident under investigation and the results which are required. It also describes, at an abstract level, the concept of breaking seemingly complex processes into a series of s

36、maller atomic parts, which should aid in the development of simple, yet robust, investigation methods. It should be considered by any person authorising, giving instruction for, managing, or conducting an investigation. It should be applied prior to any investigation, in the context of principles an

37、d processes (defined in ISO/IEC 27043:2015) and sound preparation and planning (defined in ISO/IEC 27035-21) to ensure the suitability of methods to be applied in the investigative processes described in ISO/IEC 27037:2012 and ISO/IEC 27042:2015.Relationship to other standardsThis International Stan

38、dard is intended to complement other standards and documents which give guidance on the investigation of, and preparation to investigate, information security incidents. It is not a comprehensive guide, but lays down certain fundamental principles which are intended to ensure that tools, techniques,

39、 and methods can be selected appropriately and shown to be fit for purpose should the need arise.This International Standard also intends to inform decision-makers that need to determine the reliability of digital evidence presented to them. It is applicable to organizations needing to protect, anal

40、yse, and present potential digital evidence. It is relevant to policy-making bodies that create and evaluate procedures relating to digital evidence, often as part of a larger body of evidence.This International Standard describes part of a comprehensive investigative process which includes, but is

41、not limited to, the following topic areas: incident management, including preparation and planning for investigations; handling of digital evidence; use of, and issues caused by, redaction; intrusion prevention and detection systems, including information which can be obtained from these systems; se

42、curity of storage, including sanitization of storage; ensuring that investigative methods are fit for purpose; carrying out analysis and interpretation of digital evidence; understanding principles and processes of digital evidence investigations; security incident event management, including deriva

43、tion of evidence from systems involved in security incident event management; relationship between electronic discovery and other investigative methods, as well as the use of electronic discovery techniques in other investigations; governance of investigations, including forensic investigations.Thes

44、e topic areas are addressed, in part, by the following ISO/IEC standards: ISO/IEC 27037:20121) To be published.
