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 of technical activity. I

16、SO 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 technical committee, I

19、 All rights reserved vISO/IEC 27002:2013(E)0 Introduction0.1 Background and contextThis International Standard is designed for organizations to use as a reference for selecting controls within the process of implementing an Information Security Management System (ISMS) based on ISO/IEC 2700110or as

20、a guidance document for organizations implementing commonly accepted information security controls. This standard is also intended for use in developing industry- and organization-specific information security management guidelines, taking into consideration their specific information security risk

21、environment(s).Organizations of all types and sizes (including public and private sector, commercial and non-profit) collect, process, store and transmit information in many forms including electronic, physical and verbal (e.g. conversations and presentations).The value of information goes beyond th

22、e written words, numbers and images: knowledge, concepts, ideas and brands are examples of intangible forms of information. In an interconnected world, information and related processes, systems, networks and personnel involved in their operation, handling and protection are assets that, like other

23、important business assets, are valuable to an organizations business and consequently deserve or require protection against various hazards.Assets are subject to both deliberate and accidental threats while the related processes, systems, networks and people have inherent vulnerabilities. Changes to

24、 business processes and systems or other external changes (such as new laws and regulations) may create new information security risks. Therefore, given the multitude of ways in which threats could take advantage of vulnerabilities to harm the organization, information security risks are always pres

25、ent. Effective information security reduces these risks by protecting the organization against threats and vulnerabilities, and then reduces impacts to its assets.Information security is achieved by implementing a suitable set of controls, including policies, processes, procedures, organizational st

26、ructures and software and hardware functions. These controls need to be established, implemented, monitored, reviewed and improved, where necessary, to ensure that the specific security and business objectives of the organization are met. An ISMS such as that specified in ISO/IEC 2700110takes a holi

27、stic, coordinated view of the organizations information security risks in order to implement a comprehensive suite of information security controls under the overall framework of a coherent management system.Many information systems have not been designed to be secure in the sense of ISO/IEC 2700110

28、and this standard. The security that can be achieved through technical means is limited and should be supported by appropriate management and procedures. Identifying which controls should be in place requires careful planning and attention to detail. A successful ISMS requires support by all employe

29、es in the organization. It can also require participation from shareholders, suppliers or other external parties. Specialist advice from external parties can also be needed.In a more general sense, effective information security also assures management and other stakeholders that the organizations a

30、ssets are reasonably safe and protected against harm, thereby acting as a business enabler.0.2 Information security requirementsIt is essential that an organization identifies its security requirements. There are three main sources of security requirements:a) the assessment of risks to the organizat

31、ion, taking into account the organizations overall business strategy and objectives. Through a risk assessment, threats to assets are identified, vulnerability to and likelihood of occurrence is evaluated and potential impact is estimated;b) the legal, statutory, regulatory and contractual requireme

32、nts that an organization, its trading partners, contractors and service providers have to satisfy, and their socio-cultural environment;vi ISO/IEC 2013 All rights reservedISO/IEC 27002:2013(E)c) the set of principles, objectives and business requirements for information handling, processing, storing

33、, communicating and archiving that an organization has developed to support its operations.Resources employed in implementing controls need to be balanced against the business harm likely to result from security issues in the absence of those controls. The results of a risk assessment will help guid

34、e and determine the appropriate management action and priorities for managing information security risks and for implementing controls selected to protect against these risks.ISO/IEC 2700511provides information security risk management guidance, including advice on risk assessment, risk treatment, r

35、isk acceptance, risk communication, risk monitoring and risk review.0.3 Selecting controlsControls can be selected from this standard or from other control sets, or new controls can be designed to meet specific needs as appropriate.The selection of controls is dependent upon organizational decisions

36、 based on the criteria for risk acceptance, risk treatment options and the general risk management approach applied to the organization, and should also be subject to all relevant national and international legislation and regulations. Control selection also depends on the manner in which controls i

37、nteract to provide defence in depth.Some of the controls in this standard can be considered as guiding principles for information security management and applicable for most organizations. The controls are explained in more detail below along with implementation guidance. More information about sele

38、cting controls and other risk treatment options can be found in ISO/IEC 27005.110.4 Developing your own guidelinesThis International Standard may be regarded as a starting point for developing organization-specific guidelines. Not all of the controls and guidance in this code of practice may be appl

39、icable. Furthermore, additional controls and guidelines not included in this standard may be required. When documents are developed containing additional guidelines or controls, it may be useful to include cross-references to clauses in this standard where applicable to facilitate compliance checkin

40、g by auditors and business partners.0.5 Lifecycle considerationsInformation has a natural lifecycle, from creation and origination through storage, processing, use and transmission to its eventual destruction or decay. The value of, and risks to, assets may vary during their lifetime (e.g. unauthori

41、zed disclosure or theft of a companys financial accounts is far less significant after they have been formally published) but information security remains important to some extent at all stages.Information systems have lifecycles within which they are conceived, specified, designed, developed, teste

42、d, implemented, used, maintained and eventually retired from service and disposed of. Information security should be taken into account at every stage. New system developments and changes to existing systems present opportunities for organizations to update and improve security controls, taking actu

43、al incidents and current and projected information security risks into account.0.6 Related standardsWhile this standard offers guidance on a broad range of information security controls that are commonly applied in many different organizations, the remaining standards in the ISO/IEC 27000 family pro

44、vide complementary advice or requirements on other aspects of the overall process of managing information security.Refer to ISO/IEC 27000 for a general introduction to both ISMSs and the family of standards. ISO/IEC 27000 provides a glossary, formally defining most of the terms used throughout the I

45、SO/IEC 27000 family of standards, and describes the scope and objectives for each member of the family.
