9、the International Electrotechnical Commission) form the specialized system for worldwide standardization. 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 part
10、icular fields of technical activity. ISO 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 esta
11、blished a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint techn
12、ical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

22、 BS ISO/IEC 27011:2016 ISO/IEC 27011:2016(E) ITU-T Rec. X.1051 (04/2016) vIntroduction This Recommendation | International Standard provides interpretation guidelines for the implementation and management of information security controls in telecommunications organizations based on ISO/IEC 27002. Te
23、lecommunications organizations provide telecommunications services by facilitating the communications of customers through their infrastructure. In order to provide telecommunications services, telecommunications organizations need to interconnect and/or share their services and facilities and/or us
24、e the services and facilities of other telecommunications organizations. Furthermore, the site location, such as radio sites, antenna locations, ground cables and utility provision (power, water), may be accessed not only by the organizations staff, but also by contractors and providers external to
25、the organization. Therefore, the management of information security in telecommunications organizations is complex, potentially: depending on external parties; having to cover all areas of network infrastructure, services applications and other facilities; including a range of telecommunications tec
26、hnologies (e.g., wired, wireless or broadband); supporting a wide range of operational scales, service areas and service types.In addition to the application of security objectives and controls described in ISO/IEC 27002, telecommunications organizations may need to implement extra controls to ensur
27、e confidentiality, integrity, availability and any other security property of telecommunications in order to manage security risk in an adequate fashion. 1) ConfidentialityProtecting confidentiality of information related to telecommunications from unauthorized disclosure. Thisimplies non-disclosure
28、 of communications in terms of the existence, the content, the source, the destinationand the date and time of communicated information.It is critical that telecommunications organizations ensure that the non-disclosure of communications beinghandled by them is not breached. This includes ensuring t
29、hat persons engaged by the telecommunicationsorganization maintain the confidentiality of any information regarding others that may have come to beknown during their work duties.NOTE The term “secrecy of communications“ is used in some countries in the context of “non-disclosure of communications“.
30、2) IntegrityProtecting the integrity of telecommunications information includes controlling the installation and use oftelecommunications facilities to ensure the authenticity, accuracy and completeness of informationtransmitted, relayed or received by wire, radio or any other method.3) Availability
31、Availability of telecommunications information includes ensuring that access to facilities and the mediumused for the provision of communication services is authorized, regardless of whether communications isprovided by wire, radio or any other method. Typically, telecommunications organizations giv
32、e priority toessential communications in case of emergencies, managing unavailability of less importantcommunications in compliance with regulatory requirements.Audience The audience of this Recommendation | International Standard consists of telecommunications organizations and those responsible fo
33、r information security; together with security vendors, auditors, telecommunications terminal vendors and application content providers. This Recommendation | International Standard provides a common set of general security control objectives based on ISO/IEC 27002, telecommunications sector-specifi
34、c controls and information security management guidelines allowing for the selection and implementation of such controls.
