24、dies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental an

25、d non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,

26、 Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies cas

27、ting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 27799 was prepared by Technical Committee ISO/TC 215, Health informatics. Copyright

29、 organizations and other custodians of personal health information on how best to protect the confidentiality, integrity and availability of such information by implementing ISO/IEC 270021). Specifically, this International Standard addresses the special information security management needs of the

30、health sector and its unique operating environments. While the protection and security of personal information is important to all individuals, corporations, institutions and governments, there are special requirements in the health sector that need to be met to ensure the confidentiality, integrity

31、, auditability and availability of personal health information. This type of information is regarded by many as being among the most confidential of all types of personal information. Protecting this confidentiality is essential if the privacy of subjects of care is to be maintained. The integrity o

32、f health information must be protected to ensure patient safety, and an important component of that protection is ensuring that the informations entire life cycle be fully auditable. The availability of health information is also critical to effective healthcare delivery. Health informatics systems

33、must meet unique demands to remain operational in the face of natural disasters, system failures and denial-of-service attacks. Protecting the confidentiality, integrity and availability of health information therefore requires health-sector-specific expertise. The need for effective IT security man

34、agement in healthcare is made all the more urgent by the increasing use of wireless and Internet technologies in healthcare delivery. If not implemented properly, these complex technologies will increase the risks to the confidentiality, integrity and availability of health information. Regardless o

35、f size, location and model of service delivery, all healthcare organizations need to have stringent controls in place to protect the health information entrusted to them. Yet many health professionals work as solo health providers or in small clinics that lack the dedicated IT resources to manage in

36、formation security. Healthcare organizations must therefore have clear, concise and healthcare-specific guidance on the selection and implementation of such controls. This guidance must be adaptable to the wide range of sizes, locations, and models of service delivery found in healthcare. Finally, w

37、ith increasing electronic exchange of personal health information between health professionals, there is a clear benefit in adopting a common reference for information security management in healthcare. ISO/IEC 27002 is already being used extensively for health informatics IT security management thr

38、ough the agency of national or regional guidelines in Australia, Canada, France, the Netherlands, New Zealand, South Africa and the United Kingdom. Interest is growing in other countries as well. This International Standard (ISO 27799) draws upon the experience gained in these national endeavours in

39、 dealing with the security of personal health information and is intended as a companion document to ISO/IEC 27002. It is not intended to supplant ISO/IEC 27002 or ISO/IEC 27001. Rather, it is a complement to these more generic standards. This International Standard applies ISO/IEC 27002 to the heal

40、thcare domain in a way that carefully considers the appropriate application of security controls for the purposes of protecting personal health information. These considerations have, in some cases, led the authors to conclude that application of certain ISO/IEC 27002 control objectives is essential

41、 if personal health information is to be adequately protected. This International Standard therefore places constraints upon the application of certain security controls specified in ISO/IEC 27002. This in turn has led to the inclusion in Clause 7 of several normative statements stating that the app

42、lication of a given security control is mandatory. For example, 7.2.1 states that Organizations processing health information, including personal health information, shall have a written information security policy that is approved by management, published, and then communicated to all employees and

43、 relevant external parties. 1) This guideline is consistent with the revised version of ISO/IEC 27002:2005.

44、O 27799:2008(E) vi ISO 2008 All rights reservedIn the health domain, it is possible for an organization (a hospital, say) to be certified using ISO/IEC 27001 without requiring certification against, or even acknowledgement of, this International Standard. It is to be hoped, however, that as healthca

45、re organizations strive to improve the security of personal health information, conformance with this International Standard, as a stricter standard for healthcare, will also become widespread. All of the security control objectives described in ISO/IEC 27002 are relevant to health informatics but s

46、ome controls require additional explanations with regard to how they can be used best to protect the confidentiality, integrity and availability of health information. There are also additional health-sector-specific requirements. This International Standard provides additional guidance in a format

47、that persons responsible for health information security can readily understand and adopt. This International Standards authors do not intend to write a primer on computer security, nor to restate what has already been written in ISO/IEC 27002 or in ISO/IEC 27001. There are many security requirement

48、s that are common to all computer-related systems, whether used in financial services, manufacturing, industrial control, or indeed in any other organized endeavour. A concerted effort has been made to focus on security requirements necessitated by the unique challenges of delivering electronic heal

49、th information that supports the provision of care. Who should read this International Standard? This International Standard is intended for those responsible for overseeing health information security and for healthcare organizations and other custodians of health information seeking guidance on this topic, together with their security advisors, consultant
