9、Standardization) and IEC (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 orga
10、nization to deal with particular 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 technol
11、ogy, ISO and IEC have established 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
12、adopted by the joint technical 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.

X.1051 (04/2016) v Introduction This Recommendation | International Standard provides interpretation guidelines for the implementation and management of information security controls in telecommunications organizati
23、ons based on ISO/IEC 27002. Telecommunications 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 ser
24、vices and facilities and/or use 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 contract
25、ors and providers external to 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 r
26、ange of telecommunications technologies (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 im
27、plement extra controls to ensure confidentiality, integrity, availability and any other security property of telecommunications in order to manage security risk in an adequate fashion. 1) Confidentiality Protecting confidentiality of information related to telecommunications from unauthorized disclo
28、sure. This implies non-disclosure of communications in terms of the existence, the content, the source, the destination and the date and time of communicated information. It is critical that telecommunications organizations ensure that the non-disclosure of communications being handled by them is no
29、t breached. This includes ensuring that persons engaged by the telecommunications organization maintain the confidentiality of any information regarding others that may have come to be known during their work duties. NOTE The term “secrecy of communications“ is used in some countries in the context
30、of “non-disclosure of communications“. 2) Integrity Protecting the integrity of telecommunications information includes controlling the installation and use of telecommunications facilities to ensure the authenticity, accuracy and completeness of information transmitted, relayed or received by wire,
31、 radio or any other method. 3) Availability Availability of telecommunications information includes ensuring that access to facilities and the medium used for the provision of communication services is authorized, regardless of whether communications is provided by wire, radio or any other method. T
32、ypically, telecommunications organizations give priority to essential communications in case of emergencies, managing unavailability of less important communications in compliance with regulatory requirements. Audience The audience of this Recommendation | International Standard consists of telecomm
33、unications organizations and those responsible for 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
34、 ISO/IEC 27002, telecommunications sector-specific controls and information security management guidelines allowing for the selection and implementation of such controls.
