27、tee SC 40, IT Service Management and IT Governance.DIN EN ISO/IEC 30121:2016-12 EN ISO/IEC 30121:2016 (E)4 IntroductionOrganizations of any kind face both internal and external factors and influences that can lead to the occurrence of legal actions and placement of demands on the Information Technol

28、ogy (IT) and related Information Systems (IS) to disclose digital evidence. The occurrence of legal action may be the result of an uncertain, unplanned, or unexpected event or it may occur as a planned course of action against employees, competitors, or service suppliers. Whether a risk is significa

29、nt or not will depend on the level of risk and the organizations risk attitude. Its risk attitude will be reflected in its risk criteria. Because it is almost certain that digital evidence will be discovered and, therefore, be subject to legal disclosure, organizations should plan and develop capabi

30、lity to deal with such legal actions before they occur.This International Standard is about the prudent strategic preparation for digital investigation of an organization. Forensic readiness assures that an organization has made the appropriate and relevant strategic preparation for accepting potent

31、ial events of an evidential nature. Actions may occur as the result of inevitable security breaches, fraud, and reputation assertion. In every situation, IT should be strategically deployed to maximise the effectiveness of evidential availability, accessibility, and cost efficiency.The responsibilit

32、y of the Governing body is to provide strategic direction in all matters of relevance to the organization. The Governing body is informed by principles of best practice that provide general guidance on matters of certainty and compliance. These principles may come from legal mandates, standards, or

33、social and cultural imperatives. In this International Standard, the principles come from ISO/IEC 38500 for the guidance of best practice for the governance of IT (Clause 4).Principles require implementation. The tasks of governance are to evaluate proposals and plans, to monitor performance and con

34、formance, and to direct strategy and policies. The stakeholders of an organization may provide the mandate for governance and the Governing body has the ultimate ownership of risk. A framework for the governance of digital forensic risk is established by the owners of risk taking appropriate actions

35、 to assure the strategic direction of the organization. Hence, the strategic objective is to implement the principles and to assure adequate preparation for digital investigation (Clause 5).The framework requires strategic processes to deliver direction to executives and top managers. The strategic

36、processes are selected to assure adequate scope and are principally archival, discovery, disclosure, capability, and risk criteria compliance (Clause 6).The goals derived from the principles are measureable through Key Goal Indicators (KGIs), the strategic objectives derived from the strategies are

37、measurable through the Key Performance Indicators (KPIs), and the variation between the KGIs and the KPIs measures is an indication of the organizations business performance (KBIs) (Clause 7).This International Standard should be used in conjunction with the vocabulary contained in ISO Guide 73:2009

38、; ISO/IEC 35802, Information technology Governance of IT framework and model; and ISO/IEC 38500, Information technology Governance of IT for the organization.DIN EN ISO/IEC 30121:2016-12 EN ISO/IEC 30121:2016 (E) 5 1 ScopeThis International Standard provides a framework for Governing bodies of organ

39、izations (including owners, board members, directors, partners, senior executives, or similar) on the best way to prepare an organization for digital investigations before they occur. This International Standard applies to the development of strategic processes (and decisions) relating to the retent

40、ion, availability, access, and cost effectiveness of digital evidence disclosure. This International Standard is applicable to all types and sizes of organizations.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable fo

45、dence. Those with responsibility for investigations also have the skill, independence and authority to perform those actions.4.2 StrategyThe organizations strategy development takes into account the current and future retention, availability, access to and cost effectiveness of digital evidence; the
