13、rds for management systems provide a model to follow in setting up and operating a management system. This model incorporates the features on which experts in the field have reached a consensus as being the international state of the art. ISO/IEC JTC 1 SC 27 maintains an expert committee dedicated t
14、o the development of international management systems standards for information security, otherwise known as the Information Security Management System (ISMS) family of standards. Through the use of the ISMS family of standards, organizations can develop and implement a framework for managing the se
15、curity of their information assets and prepare for an independent assessment of their ISMS applied to the protection of information, such as financial information, intellectual property, and employee details, or information entrusted to them by customers or third parties. 0.2 ISMS family of standard
16、s The ISMS family of standards1)is intended to assist organizations of all types and sizes to implement and operate an ISMS. The ISMS family of standards consists of the following International Standards, under the general title Information technology Security techniques: ISO/IEC 27000:2009, Informa

20、ommittee SC 27, IT Security techniques. 1) Standards identified throughout this subclause with no release year indicated are still under development. Information technology Security techniques Information security management systems Overview and vocabulary 4 DIN ISO/IEC 27000:2011-07 0.3 Purpose of
21、this International Standard This International Standard provides an overview of information security management systems, which form the subject of the ISMS family of standards, and defines related terms. NOTE Annex A provides clarification on how verbal forms are used to express requirements and/or
22、guidance in the ISMS family of standards. The ISMS family of standards includes standards that: a) define requirements for an ISMS and for those certifying such systems; b) provide direct support, detailed guidance and/or interpretation for the overall Plan-Do-Check-Act (PDCA) processes and requirem
23、ents; c) address sector-specific guidelines for ISMS; and d) address conformity assessment for ISMS. The terms and definitions provided in this International Standard: cover commonly used terms and definitions in the ISMS family of standards; will not cover all terms and definitions applied within t
24、he ISMS family of standards; and do not limit the ISMS family of standards in defining terms for own use. Standards addressing only the implementation of controls, as opposed to addressing all controls, from ISO/IEC 27002 are excluded from the ISMS family of standards. To reflect the changing status
25、 of the ISMS family of standards, this International Standard is expected to be continually updated on a more frequent basis than would normally be the case for other ISO/IEC standards. International Standards not under the same general title that are also part of the ISMS family of standards are as
26、 follows: ISO 27799:2008, Health informatics Information security management in health using ISO/IEC 27002 5 DIN ISO/IEC 27000:2011-07 1 Scope This International Standard provides: a) an overview of the ISMS family of standards; b) an introduction to information security management systems (ISMS); c
27、) a brief description of the Plan-Do-Check-Act (PDCA) process; and d) terms and definitions for use in the ISMS family of standards. This International Standard is applicable to all types of organization (e.g. commercial enterprises, government agencies, non-profit organizations). 2 Terms and defini
28、tions For the purposes of this document, the following terms and definitions apply. NOTE A term in a definition or note which is defined elsewhere in this clause is indicated by boldface followed by its entry number in parentheses. Such a boldface term can be replaced in the definition by its comple
29、te definition. For example: attack (2.4) is defined as “attempt to destroy, expose, alter, disable, steal or gain unauthorized access to or make unauthorized use of an asset (2.3)”; asset is defined as “anything that has value to the organization”. If the term “asset” is replaced by its definition:
30、attack then becomes “attempt to destroy, expose, alter, disable, steal or gain unauthorized access to or make unauthorized use of anything that has value to the organization”. 2.1 access control means to ensure that access to assets (2.3) is authorized and restricted based on business and security r
